Prototyping and Engineering Tips from Robogears
Powering: While this motor runs at 3V, avoid connecting it directly to a microcontroller pin. Use a small NPN transistor (like a 2N2222) or a MOSFET (like an AO3400) to switch the power safely.
Inductive Kickback: Always place a flyback diode (e.g., 1N4148) in parallel with the motor (pointing toward the positive terminal) to prevent voltage spikes from damaging your control circuit.
Secure Mounting: Because this is a cylindrical motor, use a 6mm motor clip or a small dab of hot glue/epoxy to secure it to your project. Ensure the rotating eccentric weight is not touching any part of the housing, or the motor will stall.
Frequency Control: You can vary the intensity of the vibration by using PWM (Pulse Width Modulation) from your microcontroller. A higher duty cycle results in a higher vibration frequency.
