Golden Motor HPM-10KW motor 48V-144V 20kW peak

[Lock]

I couldn't find a mention on ES about these motors, so just throwing this up here...

Listed at $765...

Presumably performs well with their controller:

Model: HPC300A/HPC500A -- Brushless Motor Controller
Voltage Range:24V/36V/48V/72V
Current (Max):300A/500A
Weight:2.2Kgs/2.7kgs
Features: Fuse breaker, Regen Braking, Temperature sensoring, Nano-second high current sampling

300A $385
500A $466

Just sayin'

That controller looks interesting... I'd like to see one cracked open.

It looks awfully similar to the Sevcon Gen4...

You will notice its what I ran on my last bicycle.

The golden controller has a rep for randomly blowing up from control glitches, but I really like its layout and heavy bus design. Its only a 36fet though, I used a 108fet Sevcon size 6 on my bicycle.

That motor has a terrible thermal path from the coils to the case. This makes its continuous power pretty crappy. Great burst power though.

@Luke: Is that the air cooled motor your talking about ?
do you have a link to that sevcon ?

Anyone tried the LC version ?

Does anybody know what controller they have used for the 120V test?

Hello, i am looking at buying a 48v HPM-10KW for a EV motorbike convertion. however i can not find the stand-still torqe ( torqe at 0 rpm) anywere on their page. and in their grafs the max rpm i somwher around 4000?
do anyone have experiance with their motor? are they any good?

The stall torque depends on the phase current you're sending the motor. The exact amount of torque is the inverse of the motors kv, so if you choose the 50kv wind you will need half the phase current to generate the same torque as the 100kv wind, but you will be limited to half the RPM (impacting gearing choices and/or top speed etc).

Contrary to popular belief, the heat production at stall will be identical if the copper fill% is identical, regardless if you're sending it 100amps to a 50kv motor or 200amps to a 100kv motor to generate the same amount of torque. This is because while the heating increases at the square of current, the winding resistance also grows at the square of turns, so they balance.

i emaild them and askt what the torqe was for the 48V one at 0rpm, they said that it would be 85nm
and that the max rpm is 3900

Its a little silly of them to say that to you if you didn't specify a controller and it's phase current setting, but hopefully it puts you in the ball park.

Looking at the motors torque constant and the phase amps your planned controller outputs would be a much better way.

That motor makes a pretty good bicycle motor, but I ended up burning it up of course.
