Motors

The resistance values for the CR motor and the PF motor are given below, however, the values cannot be used to check the motors status since they are DC motor and the resistance between the electric poles varies. Visually check the motors for abnormal operation and if it is hard to judge, replace the motor.

Motor resistance and check point

Motor	Motor Type	Drive Voltage	Resistance
CR motor	DC motor with brush	DC 42 V ± 5%	22.7 Ω ± 10%
PF motor			21.2 Ω ±10%
