Answer：The current module system of new energy vehicles is composed of many parts, such as battery, VCU, BSM, motor, etc., but these are relatively mature products. The internal emphasis is on the motor drive part, which is the core component of the motor d...
Answer：As an important choice for future travel, new energy vehicles rely on advanced technology to achieve efficient energy conversion and environmental performance. Nowadays, more and more consumers have begun to choose new energy vehicles. As the disadva...
Answer：For a three-phase asynchronous motor, the stator windings (with sinusoidal spatial distribution and p-poles) are connected to a three-phase symmetrical voltage supply to generate a rotating magnetic field. The rotor winding is usually a squirrel-cage...
Answer：Once the permanent magnet motor loses its magnetism, basically you can only choose to replace the motor, and the maintenance cost is a lot. How to judge the loss of magnetism of the permanent magnet motor, let's look down.
Answer：A DC motor consists of a stator, a rotor and other components.
Answer：This should be considered from three aspects, that is, the design and manufacturing price range, and how to create a motor with greater power . On the basis of the existing finished motor, how to increase the power? Divided into two major measures, t...
Answer：Motor introduction: It is a device that converts electrical energy into mechanical energy . It uses energized coils (that is, stator windings) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminu...
Answer：What is slot fill rate? That is, the ratio of the cross-sectional area of the conductor in the iron core slot to the total area of the iron core slot, the higher the motor slot full rate means "the more copper wires are filled in the iron core
Answer：In wound-type induction motors and brushed DC motors, the carbon brush is a very critical electrical component, that is, through a good dynamic connection, it solves the circuit composition during the operation of the motor. However, the function of ...
Answer：Induction motors can generally be divided into cage type motors and wound type motors according to the structure of the rotor winding. Most of the cage-type rotor windings use cast aluminum rotors, that is, molten aluminum is cast in rotor core slots...
