- 2024-12-12Causes and solutions for the spot on the transformer housing
The transformer housing is charged mainly because there is a voltage difference between the housing and the ground, which causes a high potential on the housing. This voltage difference may be caused by insulation damage between the housing ...
- 2024-12-11Common faults of motor cores
1. Short circuit between silicon steel sheets caused by insulation damage; 2. Loose core caused by poor tightening and motor vibration; ...
- 2024-12-10Steps for modifying a single-phase series-excited motor
According to the selected modification plan, make corresponding modifications. For example, if you choose to increase the excitation resistance, you need to add a resistor to the motor winding; if you replace the rotor, you need to remove th ...
- 2024-12-06How to effectively avoid motor burnout?
The technical status of the motor starting equipment plays a decisive role in the normal starting of the motor. Practice has shown that the vast majority of burnt motors are caused by abnormal operation of the starting equipment ...
- 2024-12-05Common faults of explosion-proof motors
Explosion-proof motors, as the name implies, are motors that can be used in flammable and explosive places because they do not generate electric sparks when running. ...
- 2024-12-04Introduction of motor parts
The pole shoe in the motor connects the stator and rotor of the motor, so that the stator and rotor can rotate with each other. Without the pole shoe in the motor, the stator and rotor cannot be connected, and the motor cannot operate. ...
- 2024-12-03The difference between shunt excitation and separate of DC m
A DC motor is a motor that converts DC electrical energy into mechanical energy. According to the different excitation methods, DC motors can be divided into two categories: separately excited DC motors and shunt-excited DC motors. ...
- 2024-12-02Discuss the causes of AC motor running at low speed
Power supply problem can be one of the main reasons for AC motor running at low speed. If the power supply voltage is lower than the rated voltage of the motor, the motor will not work properly. If the power supply voltage is unstable or the ...
- 2024-11-29Motor temperature requirements and related precautions
A single-phase motor coil is a coil wound by wire. It is one of the main components of the motor and is mainly composed of a coil body, an insulation layer and a connecting wire. Coil body: A coil wound by wire, which directly participates ...
- 2024-11-28How to judge the quality of single-phase motor coil
1. Composition of single-phase motor coil A single-phase motor coil is a coil wound by wire. It is one of the main components of the motor and is mainly composed of a coil body, an insulation layer and a connecting wire. Coil body: A coil w ...
