Description
This motor has a whining resonant sound when it runs at low speed. It will disappear when running at high speed above 24V. It is estimated that it will improve under running-in operation. Add some lubricant to the tail bearing of the new machine.
The nominal voltage of the motor is 36V. According to experience, the maximum power is estimated to be around 300-400W. The actual test of the motor can work at 12-36V. The voltage is low and the power is low. The test torque is still very good even if the voltage is reduced to 12V. The torque of the rotor is better than that of the 5-pole motor of the 885 motor. This is still neodymium magnet, and the locked-rotor current of 12V voltage is about 20A. It is more violent when it is used at 36V and the speed is more than 17000 rpm.
The motor is tested at 12V, 24V and 36V speed as follows:
12V voltage, no-load current 1.7A, no-load speed 5800 rpm.
24V voltage, no-load current 1.9A, no-load speed 11700 rpm.
36V voltage, no-load current 2.3A, no-load speed 17,600 rpm.
The motor weighs 505 grams.
