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...
Answer：For small-sized motors, sealed bearings are mostly used, which do not require special bearing covers. The end covers have shaft holes, and wave springs are placed at the bottom of the bearing chamber during assembly to meet and limit the axial displa...
Answer：The air gap is the space between the stator and rotor of the motor. During the operation of the motor, the stator does not rotate, but the rotor needs to rotate relative to the stator. The air gap is necessary for the operation of the motor; the size...
Answer：A motor factory has manufactured nearly 100 YKK high-voltage motors for customers, with frame sizes ranging from H450 to 710. The heat load was designed to be very low, and the design temperature rise was lower than 68K. However, within less than hal...
Answer：The rotor part of the motor product usually needs to be supported by two sets of bearings, and the rotor is radially and axially positioned relative to the stator. According to different usage requirements, such as load, required rotation accuracy, a...
