New original 887 power high speed motor Super thick and high current compensated carbon brush Front and rear ball bearings 7 pole motor rotor Originally used in the brand 36V electric garden machinery tools above, power-driven high-power motor, power greater than 775 motor. The nominal voltage 36V of the motor is estimated by experience. The maximum power is about 300-400W. 12-36V can work in actual testing of motors. Low voltage, low power and low speed, even if the voltage is reduced to 12V, the torque is very good. The 7-pole rotor torque of the 887 is better than that of the 5-pole motor of the 885 motor. The short-circuit current of the 12V voltage is also more than 10A. It is more violent to use the 7-pole rotor torque of the 36V voltage to speed up to 1700 rpm. The motor speed tested at voltage 12V and 24V and 36V is as follows: 12V voltage, no load current 1A, no-load speed 5700rpm 24V voltage, no load current 1.2A, no-load speed 11000rpm 36V voltage, no load current 1.5A, no-load speed 17500rpm Motor weight: 445g Self-contained cooling fan for efficient heat dissipation
