Micro geared motor speed regulation failure how to solve?

Miniature geared motor is very widely used, in the application process sometimes need to speed control of the miniature geared motor, in the speed control process there will be inevitable failure, how to solve the speed control failure of the geared motor? The following will analyze for you

1. the power supply voltage is too low, use a voltmeter to measure the voltage at the input of the motor, and make the necessary adjustments.

2. If the delta connection of the motor winding is inadvertently connected to the star connection, this can be solved by switching to the delta connection.

3. If there is poor contact with the winding rotor brushes, check the contact parts of the brushes and the starting varistor.

4. Improperly wired or misdirected local coils on the stator and rotor windings, check the correct wiring of the faulty coils.

5. Too many turns of winding and rewinding, wind and rewind with appropriate number of turns.

6. When the winding rotor is out of phase, check with a calibration lamp or multimeter before repairing.

7. Poor contact between brush and collector ring can be improved by grinding the working surface of brush, adjusting the pressure of brush, twisting the surface of collector ring, etc.

The above is to introduce you how to solve the speed control fault of the gear motor, I hope it will help you, for more information, please feel free to consult Vshida micro motor
