Motors & Transformers
Two motors that weigh the same can be worth very different amounts, because what actually drives value is how much copper winding is inside, not the total kilograms on the scale. Here's what to know about motors, alternators, and transformers before you sell.
Fractional-horsepower motors from appliances and tools, lower total copper content but still genuinely worth sorting from general mixed scrap rather than binning whole.
Larger motors from pumps, compressors, and machinery carry significantly more copper winding relative to their size, the single biggest factor in what they're actually worth.
Automotive-specific units, smaller than industrial motors but generated in real, steady volume through vehicle servicing and end-of-life processing.
Copper or aluminium windings around a steel core, sized from small electronics transformers up to substantial industrial units. Very old transformers, pre-1980s, can contain PCB-treated oil requiring specialist handling, worth flagging honestly if you're dealing with genuinely old industrial stock.
An electric motor is essentially a steel or aluminium housing wrapped around copper windings, and it's the copper that carries most of the value, not the housing. A larger industrial motor generally packs proportionally more copper relative to its total weight than a small appliance motor does, which is why size and application matter more than raw kilograms when it comes to actual value.
Stripping the windings out yourself is possible but rarely worth it for a small amount, the labour involved in cleanly extracting copper windings takes real time, and the housing itself still has scrap value once separated. For genuine volume, it's worth checking directly with a buyer whether they prefer units stripped or intact, since preferences vary.
Worth flagging honestly rather than glossing over: very old industrial transformers, pre-1980s in particular, can contain PCB-treated insulating oil, a substance now tightly regulated because of its environmental and health risks. Modern transformers don't carry this issue, PCBs in this application have been phased out for decades, but genuinely old industrial stock is worth checking before disposal rather than assuming it's handled the same as a standard scrap motor. As for the platform side: motors and transformers aren't their own live-priced calculator category, value depends too much on the specific unit's copper content and condition. List them on the general marketplace with clear photos and any known rated size, then negotiate directly or post to the Wanted Board.
Motors and transformers follow industrial equipment turnover, vehicle servicing, and infrastructure upgrades. Newcastle and Wollongong both carry dense, genuine industrial and manufacturing bases where motors, pumps, and process equipment turn over regularly, generating real, ongoing volume of this material alongside their better-known heavy industry.
Neither city is a requirement. Electricians, mechanics, and industrial maintenance contractors generate this material anywhere in Australia, and ScrapTrade connects buyers and sellers nationally regardless of where a listing is posted from.
The copper inside a motor or transformer winding is chemically identical to any other clean copper once it's recovered, and the steel housing recycles fully too, this is genuinely a two-metal recovery opportunity in a single unit. That's exactly why a properly assessed motor or transformer, priced on its real copper content rather than a flat per-kilogram guess, is worth meaningfully more than treating it as generic mixed scrap.
The same logic scales down to smaller units too. Even a handful of appliance motors, household fans, pumps, power tools, add up to a genuine amount of recoverable copper once accumulated, worth keeping separate from general mixed metal rather than tossing them in with steel offcuts and other unrelated scrap as they come out of repairs or clean-outs.
A motor priced by weight alone, without anyone actually assessing its copper content, is exactly how sellers end up underpaid on this material. On ScrapTrade, you describe the unit properly, size and application included, then negotiate directly with an interested buyer or post it to the Wanted Board so someone who genuinely assesses motors and transformers can make you a real offer, negotiation is on by default on every listing. Every listing is GPS-video verified before it goes live, and payment sits in escrow from the moment a deal is confirmed until pickup or delivery is done, so neither side is exposed first. The full case for why that beats a single yard quote is on Why Choose ScrapTrade and Trust & Safety.
Copper winding content relative to overall weight, more than anything else. A large industrial motor with substantial copper windings is worth more per kilogram than a small appliance motor with a thin steel casing and comparatively little copper inside it, even though both are technically "electric motors."
Usually not for a small amount, extracting windings cleanly takes real time and the motor's outer casing (steel or aluminium) is worth something too, so an intact motor sold as-is often nets a similar or better outcome once labour is accounted for. For genuine volume, it's worth checking with a buyer whether they prefer stripped or intact units.
Similarly in principle, copper or aluminium winding content drives the value, but be aware that very old industrial transformers, pre-1980s in particular, can contain PCB-treated insulating oil that requires specialist, regulated handling rather than standard scrap processing. If you're dealing with genuinely old industrial equipment, checking this before disposal matters.
Not as their own calculator category, since value depends so much on the specific unit's copper content and condition. List them on the general marketplace with clear photos and, if known, the motor or transformer's rated size, then negotiate directly or post to the Wanted Board for a buyer who assesses this material regularly.
They can, but usually shouldn't if you want a fair price, mixing them into general steel or mixed-metal scrap means their real copper content gets averaged down rather than valued properly. Keeping them as their own category, even loosely sorted by size, tends to get more total value.
Worth keeping separate, even a handful of small motors accumulated over time adds up to genuine recoverable copper. They're rarely worth listing individually the moment you have one, but building up a small collection before listing is a reasonable approach for a household or a small workshop.
No, working condition is irrelevant for scrap purposes, a seized or burnt-out motor still has the same copper winding content as a working one. If it's genuinely broken and you're scrapping it rather than repairing it, its condition doesn't change what it's worth as scrap material, only its physical condition and copper content do.
Describe it properly, negotiate directly, or post it to the Wanted Board.
