Newbie question:Other than Curtis and NetGain, are there any other brand of motors I should know about?
Silly question:Is it possible to buy a Yasa motor?
Thanks in advance.

There is a giant thread here in the motor subforum about repurposing forklift motors. Basically, any DC forklift would be fine. You can get them for free, to about $200 in scrap if you're polite. They have no value to anyone, forklifts get thrown away when their batteries are bad, motors last forever.

They'll be roughly identical to Netgain motors, for 2-5% the price.

That's not so silly. Most manufacturers of modern motors (not brushed DC motors) are not interested in selling individual motors to hobbyists, so you need to find a distributor, and even then they may not be available.

There are lots of motor manufacturers. There are several who make motors which are suitable for EVs, but most of them are either not available to individual purchasers, or are very expensive. The recent trend is to salvage motors from production EVs, most commonly (but not exclusively) Teslas and Nissan Leafs.

The YASA motors are unusual in design compared to most electric motors that might be used in an EV, and would normally be chosen only by someone who wants their specific characteristics... including the "pancake" shape.

By Curtis I meant the HPEVS AC motors
EV West put Curtis in as well
Sorry
That makes more sense. EV West and others bundle HPEVS motors with Curtis controllers, but there are other controllers which would work.

The HPEVS motors are the most common induction motors used in DIY EV conversions, although Siemens motors have been used in professional conversions and are sometimes found as used "new old stock" (mostly unused Siemens motors left over from the bankruptcy liquidation of Azure Dynamics), and there have been other brands. The Ford Ranger EV used a Siemens motor.

Until recently all Tesla Model S and X motors, and the front motor in the Model 3 and Y, are induction motors, but of course those are only available as used salvage.
