View Full Version : HPEVS encoder

Would one of you happen to know the brand and model encoder used on the HPEVS AC motors.

Mine needed to be replaced on an AC30 and although I figured out the manufacturer, the part was an OEM spec and thus not available (cheep) off the shelf... Hope that helps. Bill at HPEVs found me one off a junk motor or out of a drawer of parts. Check with them.

Let me know, I sell HPEVS equipment and parts and can get you one no problem.

Hi guys I appreciate the replies. I spoke to a guy at HPEVS whose name I think was Bill and he quoted a price of $50 for that encoder. That doesn't seem bad but it isn't for one of those motors. I've bought two induction motors. One is a lesson the other is a gm eassist motor. They'll be used with Sevcon espAC. The leeson motor has no encoder and the gm has a resolver to my understanding. The espAC and Gen4 mmanuals both spec either a constant current or open collector encoder.

You'll just need to follow the specs in the espAC controller manual. The encoder is programmable as far as the pulses per revolution. I think they're AB encoders, but you'd need to check. I doubt the encoder would be the same for you as with the HPEVS motors.

Why do you say that?
I figured if they were AB encoders then it would be a matter of configuring the parameters in DVT like thePPR. The manual mentions the same SKF or Thalheim eencoders as the Gen4 manual but those seem pricey.

Physically different I mean. The encoders they have are made to fit the HPEVS motors on the non-drive end bell, beneath the fan.

Here's a picture of the two motors

What would be a suitable encoder and where would it be bought. I looked on Mouser and digikey and found an HEDS 5500-S13

That's why I was trying to find data on the hpevs encoder to compare and contrast as that one is a know used item.
