- 2024-09-19What are the basic characteristics of high-efficiency motors
As the country's requirements for product energy saving continue to increase, it is a challenge for any motor manufacturer. One is the challenge from motor technology, and the other is the challenge from manufacturing costs. However, most mo ...
- 2024-09-18Why is differential protection used on large high-voltage mo
Compared with small and medium-sized motors, high-voltage motors are expensive and are used in critical and special applications. Whether it is the disposal of the motor body after a failure or other problems ...
- 2024-09-14What is the impact of heat dissipation medium on temperature
Temperature rise is a very critical performance indicator of motor products. When the temperature rise of the motor is high, on the one hand, it will affect the surrounding environment, and on the other hand, it is directly related to its ef ...
- 2024-09-13Key points of quality control in high-voltage motor manufact
The motor is a relatively simple machine. When the stator and rotor are put together and the two end covers are buckled, it is a complete motor. However, such a simple machine integrates electromechanical energy conversion and the essence of ...
- 2024-09-12Factors causing overheating and burning of motor windings
1. Motor winding short circuit When one phase of the motor winding is short circuited, or one of the parallel branches is short circuited, it will cause the three-phase current to be unbalanced, causing the motor to overheat. ...
- 2024-09-11Rotor problems in permanent magnet motor applications
Different motor products have different advantages and applicability. Due to different working conditions, the requirements for motor product parts are also different. For example, for heavy-load working conditions, there are special require ...
- 2024-09-10Motor shaft voltage test method
The purpose of measuring the motor shaft voltage is to understand the magnitude of the motor shaft current. When the motor shaft current reaches a certain level, it will cause the motor bearing to overheat, the bearing or bearing seat to hav ...
- 2024-09-09Why can't the voltage withstand test be repeated?
The withstand voltage test is a test of the insulation performance of the motor during the production and processing of the motor winding and the test of the whole machine product. The standard for qualification is whether the motor is not b ...
- 2024-09-06Is the number of poles of the motor rotor fixed?
The number of rotor poles of a motor refers to the number of magnetic poles on the motor rotor; the number of rotor poles of a motor affects the motor speed and torque. For cage-type motors ...
- 2024-09-05Necessity of safety upgrade of standard increased safety mot
1. Increased safety explosion-proof motors are widely used in flammable and explosive hazardous places, and their explosion-proof performance is closely related to safe production. At present, a large number of increased safety explosion-pro ...
