HPM 3000 no load amps question

[Mayhem79]

Anyone have any no load amps data? Full throttle at 52 volts I'm showing 8-9 amps. Seems high to me.

thanks

Hi andto the forum.

According to the dynamometer data for the 3kW motor 8-9 amps sounds reasonable.

The lowest current shown in the above test figures at maximum rpm is almost 15 amps, but as the motor is still producing 0.7Nm of torque, there must be a slight load on the shaft (this would explain why the current is at least 50% higher than your test).
