Electric Motor Rewinders and Repairers

AG has a long history of working closely with a variety of electric motor, generator and electromagnet repairers and manufacturers spread across Australia and the Asia-Pacific. Our network of branches combined with our highly trained and experienced personnel and some of Australia’s largest electrical insulation stock holdings ensure we are uniquely positioned to offer the high levels of service and fast delivery demanded by an industry that measures lead times in days (if you’re lucky).

As an independent and wholly Australian owned company, AG is not locked to any particular brand which allows us to offer the very best material for your application. Though we have partnered with world-leading insulation manufacturers such as DuPont, Isovolta,, Haysite, Fiber-Tek and many more, AG will work with you to identify the best fit for your requirements, rather than sheparding you towards the product that best suits us.

By combining our comprehensive stock of raw materials with our extensive fabrication facilities, AG is also able to supply custom made insulation components on incredibly short lead times. The sections below provide more information on just some of the products commonly sought by companies in these industries. For more information on any single item, or to discuss how AG can assist you, please do not hesitate to contact your local AG branch.

Products for Electric Motor Rewinding

ELECTRICAL INSULATION TAPES

We are pleased to be able to offer a range of electrical insulation tapes to cover almost any conceivable application. This range is, in fact, so large (and continuing to grow) that we have split it into two sections, standard and specialised.

Our standard electrical insulation tape range features everyday styles like our those in our Woven Electrical Tape rage which includes Woven Glass, Varnished Glass, Woven Shrink, Woven Polyester and Woven Glass / Polyester. These are all stocked in a number of different sizes as are our Cotton Tapes (both Egyptian and Cotton Webbing).

Our Edge Restraint Tape (AKA HyperEdge) is also available in a huge selection of sizes and, since it is made in-house by Associated Gaskets, can be produced in a size to suit individual applications.

Our adhesive tape range is no less diverse. Oftentimes, we offer many different brands of a similar style so you can pick the one that offers the best features for the price. This is definitely true with our Adhesive Glass Tapes, Adhesive Polyester Tapes and Adhesive Polyimide (AKA Adhesive Kapton) tapes. We also stock a wide range of Adhesive PVC Tapes and Rubber Insulation Tapes like 3M Scotch 23, Scotch 70 and our specialised Arlon Silicone Self-Fusing Level Wrap Tape.

In addition to these electrical tapes, we also have those that are commonly used in and around electrical applications. We stock a number of different grades of masking tapes as well as Dunstone Hi-Shrink Polyester Tape which is designed specifically for compacting and securing coil insulation.

The vast, vast majority of our electrical insulation tapes are not only stocked by AG but are slit in-house. This enables us to provide you with the option of ordering in either standard or custom widths to suit the particular needs of a job. For more information on our slitting capabilities, or to discuss any of the tapes in our comprehensive insulation range, please don’t hesitate to contact your local Associated Gaskets branch.

SPECIALISED INSULATION TAPES

Complementing our range of standard electrical tapes, Associated Gaskets is proud to offer a full range of more specialised styles. This range has been developed over our years of working with motor rewinders and will continue to grow and expand as new options become available and new requirements are identified.

As of now, our range of specialised tapes includes high quality solutions from world-leading manufacturers like Isovolta, Arlon, DuPont, 3M, Fiber-Tek and more. Of these, the Isovolta range is perhaps the largest and includes everything needed for high voltage motor rewinding. Whether you need a mica tape for a resin rich or VPI system, a conductive coil tape, tapes for end-winding or overwrap tapes for insulation consolidation, the Isovolta range has you covered.

We are also proud to be the official Australian distributors for two US based manufacturers, Fiber-Tek and Arlon. Arlon manufactures the previously mentioned Silicone Level Wrap Tape and is also the manufacturer of our Silicone Fibreglass Reinforced (AKA Sil/Glass) range. Fiber-Tek produces both our Res-I-Flex Armor Tape and is also the manufacturer of our Banding Tape which is available in a number of different sizes and roll lengths to suit either manual or machine-assist coil banding techniques.

Another relationship that we are very proud of is our longstanding agreement with DuPont. This enables us to offer their full range of electrical insulation products headlined by Nomex and Kapton. We stock both in a wide range of tape thicknesses and widths and, thanks to our slitting facilities, are also able to produce custom sized Nomex and Kapton Tapes to suit the needs of your application when required.

Finally, we have our 3M Electrical Tapes. Many were mentioned under the standard insulation tapes category but some deserve their own mention here. These include our EMI Shielding Tape range which features many different types and styles of specialised aluminium, copper or tin-plated shielding tape. These are all slit in-house at AG and can be provided in custom width rolls or, if it suits your requirements better, die-cut components.

Like the rest of the types of insulation discussed on this page, we will continue to grow and expand our range of specialised insulation tapes. We are constantly on the look-out for new solutions and love to work with our customers to find products that work in new applications. If you would like assistance in choosing a insulation tape for one of your applications please do not hesitate to contact us.

CLEANERS AND DEGREASERS

Whether you need to clean heavily soiled motor casings, parts prior to bonding them or the workshop floor; Associated Gaskets’ range of industrial grade cleaning and degreasing solutions may be of interest. For this range, we’ve once again partnered with Weicon to offer German quality products that save time and money.

This range includes gentle cleaners like our Plastic Cleaner, Citrus Cleaner and Electro Contact Cleaner which are all able to be used on sensitive surfaces (like copper) without damaging the metal. For heavier duty cleaning we offer solutions like our Cleaner S, Parts and Assembly Cleaner and Sealant and Adhesive Remover which is designed specifically for removing old, caked-on labels and adhesive residues.

The aforementioned are really only a small subset of our full range; a range that includes our Workshop cleaner (which can be diluted with water to suit the job) and Surface Cleaner (all-round cleaning agent). Many more specialised products are also available.

The vast majority of products in our cleaning and degreasing range are available in both aerosol and bulk liquid form so you can choose the best option for your workshop. We’re also here to help and assist. If you would like to talk about the best ways to minimise time and labour spent cleaning parts used in a particular area, please don’t hesitate to contact us.

SPECIALISED FABRICATED SOLUTIONS

With over 50 years of experience in producing custom made electrical insulation components, you can count on Associated Gaskets to assist with the design, production and delivery of what you need to get the job done.

The range of parts and components produced for motors over the years includes everything from standard slot wedges and spacers (produced to tight tolerances and turnaround requirements by our slot wedge department) to fully machined coil supports, terminal blocks, formed conductors and arc chutes. The majority of the time, these have been made based on old samples, drawings or dimension lists and delivered to suit tight lead time requirements.

We combine large quantities of raw material stock with fully equipped production facilities to be able to deliver fabricated parts to suit the needs of your job. Perhaps the most important part of the process is our experience though. This means we understand that you often don’t know what you need until you get the motor apart, but that by that point the clock is already ticking on when you need the motor out the door.

If you do have a particularly hairy job, or would like to talk to us about the feasibility of getting a particular insulation component custom made, please do not hesitate to contact us. We’ve found through experience that doing so is not only oftentimes faster than sourcing from the OEM, it’s a lot cheaper too.

LUBRICANTS AND CORROSION PROTECTION

Here at Associated Gaskets we are pleased to offer a comprehensive range of lubricants and corrosion protection solutions. The full range is quite large but there are a few that have proven to be of particular use to motor rewinders so it is these we focus on here.

Our range of lubricants and corrosion protection can be broken down into a couple of sections. The first of which is our lubricating and multi-functional oils. This range includes our W44T Turbo Power Spray (which provides water resistance, corrosion protection, lubrication, cleaning, preservation and creep in one), AT-44 All-round Spray with PTFE, Silicone Spray, PTFE Spray and Top-Lub (used for permanently lubricating highly stressed mechanical parts). Many of these are available in both liquid and aerosol form so you can choose the type best suited to your workshop.

Next in this range is our selection of Anti-Seize products. Once again, we are proud to have partnered with Weicon to offer very high quality solutions at excellent prices. Our range of Anti-Seize includes our Anti-Seize standard, copper paste and the specialised Anti-Seize High Tech which is completely metal-free with good electrical properties. All three types of Anti-Seize are available in a huge selection of container types and sizes to suit various requirements.

Fairly new to Associated Gaskets is our range of All-Round Lubricants. These quality greases have been designed to perform in demanding industrial situations and are each available in a selection of sizes and cartridges. These are used to lubricate different types of bearings, joints, guides, spindles, shafts, springs, gears and cables and combine good performance with long re-greasing intervals. The five types available cover different temperature ranges, applications and special requirements.

Finally, we have our range of corrosion protection products. Though not widely used by the motor rewinding industry for their work, we mention them because we have had experience with them being of use for protecting parts and equipment in the workshop. This range includes a number of metallic sprays (such as our Zinc Spray, Copper Spray and Zinc-Alu Spray) which are used to protect exposed metal parts and cover exposed welds.

In addition, we are also pleased to present our Corro-Protection Spray and Fluid. This forms a transparent, protective layer that has been proven to protect parts from corrosion in even the most demanding of applications. It’s perfect for ensuring that seldom used part stored out the back of the shed doesn’t rust and is very easy to remove when the time comes (a little Cleaner S does the job).

ACCESSORIES AND OTHER ELECTRICAL PRODUCTS

Over the course of decades spent working with our customers in the rewinding industry, we’ve been asked to help in sourcing and supplying a pretty large range of products and parts. Through this experience, we’ve built up and continue to carry large stock quantities of many different types of accessories and electrical insulation products often used for rewinding.

Our range includes Plastic Motor Fans, Preformed Slot Wedges made from Wood, DMD and Nomex, capacitors, anti-condensate heater cables and Microtherms. We also carry stock of numerous sizes of plastic terminal blocks (in addition to the higher voltage ones we can manufacture), stand-off insulators and more specialised products like mica dust and Nomex wool and felt.
