What Are The Reasons For The Failure Of DC Gear Motor Resistance?

Inevitably in the long-term use of DC geared motor in the process of resistance failure problems, so what are the causes of the failure of the geared motor resistance? The following will give you an introduction

1. winding fault aspects: including inter-turn short-circuit fault and multiple contacts between winding and housing, resulting in ground fault.

2. Aspect of winding connection: The connection wire, lead length or cross-sectional area of the wheel geared motor does not match the specifications. Check the law of winding element connection, and correct the wrongly connected element.

3. Wire breakage aspect: broken at the joint wire hum; broken wire at the circle lead or bend; broken wire in the winding wire or parallel branch circuit. Check with the meter, gently shake the wire, the meter pointer will swing with the wire break with a test light or insulation resistance table to check the more convenient, check out after re-welding good.

4. electromagnetic wire specifications: uneven thickness of the magnet wire, there are qualified and unqualified

5. rewinding coil process: reducer motor coil size is not standardized, the number of coil turns is not correct, the line tension is not uniform.

The above is the cause of the failure of the DC gear motor resistance, I hope you have a reference, more related information welcome to contact us at any time
