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...
Answer：For electric motor products, the whole machine involves processing datum and installation datum. The motor base foot surface and flange end cover installation plane are the most common installation datum planes. In the machining process of parts , an...
Answer：Whether it is a stator winding or a rotor winding, whether it is a soft winding or a hard winding, its ends must be bound during the manufacturing process; theoretically, the purpose of binding is to ensure that the relative positions of windings, wi...
Answer：Whether it is a motor inspection test or a type test, the motor will go through the motor starting process. Especially for the case of large motor power and small grid capacity, it will be very difficult to start the motor without load. The test proc...
Answer：Top 10 hot new technologies in the field of drive motors in 2024
Answer：Compared with low-voltage motors, local discharge usually occurs in the insulation structure of high-voltage motors, but the size, quantity and location of local discharge depend on the design, material, manufacturing process, quality, operating envi...
Answer：Compared with the motor stator, due to the special nature of the rotor part rotating, the rotor must have the performance of anti-deformation. For example, the rotor slot wedges and radial fixing of the winding ends of the wound rotor motor are to pr...
