I am having trouble running this gearmotor at low speed. Even with nothing connected to the output shaft, I see the following behavior. Note that for testing I am using my benchtop power supply directly connected to the motor:
- As I raise the voltage from 0V, the motor does not start turing until I’ve reached a voltage of 1.8V. Current rises to 1.68A until the motor starts turning and then drops down to 0.22A.
- Once the motor is turning, I can decrease the voltage down to 0.5V before the motor stops turning.
Is this normal behavior?
