Frequently asked questions
What supply voltage should I use?
The listing states a 3 V motor voltage, but the speed and current figures are given at 6 V. Choose a supply that matches the performance you need, and make sure your driver can handle the 200 mA stall current listed at 6 V.
How do I reverse the motor and protect the driver?
Reverse the direction by swapping the polarity of the supply. Drive the motor through a transistor, MOSFET or motor driver, and place a flyback diode across the motor terminals to protect the switching device.
