I don't see where Stirling got 53 v from, it's not in the data provided afaics.
It's there, you just have to use ALL the data @golash provided. The label on the motor in one of the ebay pics gives you your google search for the data sheet etc. etc. which is exactly what I did and Gerry has confirmed.
So to drive that motor to max speed and torque you use 1.6A at 53 volts. Any less of either and you're driving the motor under it's potential speed and torque (which is fine if it's enough for your purposes), any more of either and you're abusing the motor.
Hi
So its a bipolar drive I believe.... so is that 1.6 x 2 phases =3.2 amps
No - set your drive to 1.6A
