6. Support duty cycle range: 0-100%

7. Mounting hole diameter: 3 mm.

8. Size: 49*39*14mm 9. Weight: 28g

10.Packing form: anti-static bag packaging

Precautions

01. The motor stops first and then reverses

When the motor is commutation, the motor needs to stop or brake. The recommended time is greater than 0.5 seconds, otherwise the instantaneous current of the immediate commutation may burn the module;

02. Do not reverse the positive and negative poles

Do not connect the positive and negative poles of the power supply in reverse, otherwise it will burn. Do not connect the power supply to the motor interface.

03. The frequency should not be too high

In order to improve the effective work efficiency, a small DC motor generally uses 400HZ. The maximum PWM frequency is recommended to be within 2KHZ. If the frequency is too high, the module will easily generate heat.
