Answer：For small and medium-sized motors, there are two most common shaft extensions, namely cylindrical and conical. A careful observation reveals that motors used in lifting and metallurgy generally use conical shaft extensions, while most other load moto...
Answer：Phase loss is an electrical fault unique to three-phase motors. It may occur during the test phase of the motor or during the use phase of the motor. It may be a problem with the manufacturing quality of the motor or a problem with the use of the mot...
Answer：Compared with other mechanical equipment, motor products involve multiple engineering parameters such as mechanical, electrical and wind circuits, and are relatively complex mechanical products. From the perspective of the mechanical performance of t...
Answer：Any electrical product, including motor products, has specified rated voltage for normal operation. Any voltage deviation will have adverse consequences on the normal operation of the appliance.
Answer：The coil is the key to motor manufacturing. The quality of the coil depends on the quality of the electromagnetic wire on the one hand, and on the processing technology of the coil on the other hand, which mainly includes winding, molding and insulat...
Answer：Compared with industrial frequency motors, variable frequency motors are characterized by the change in speed. When the speed is adjusted, the motor's input voltage, current, torque, power and other parameters will also change. Some netizens hav...
Answer：Variable frequency and variable pole speed regulation are two completely . Variable pole speed regulation can only achieve multiple speed gears for the same motor, and the corresponding gears correspond to constant speeds; while variable frequency sp...
Answer：Insulation performance to ground is a performance requirement that any electrical product must have, and motor products are no exception. The live parts of the motor should be effectively isolated from other parts by the necessary insulating medium, ...
Answer：Low-resistance semi-conductive anti-corona paint is generally directly applied to the surface of the winding slot, or the glass ribbon is first dipped in anti-corona paint and then wrapped around the surface of the slot winding to improve the electri...
Answer：According to the material characteristics of the motor rotor slots, there are wound rotors, cast aluminum rotors and permanent magnet rotors. In comparison, cast aluminum rotors are the most widely used, of course, due to some cost and process advant...
