Process of high voltage ac motor
Stator
The fixed part of a motor called the stator on which a pair of stationary main poles for DC excitation are installed Stator windings can be divided into two types: centralized and distributed according to the winding shape and embedded wiring These windings generate magnetic fields when they are energized to provide the necessary electromagnetism for the operation of the motor. Stator punching sheet adopts high-speed multi-slot punching stator core adopts external pressing process winding is manufactured by special equipment manual off-line vacuum impregnation electrical insulation test.
Rotor
The rotating part is called rotor. It is equipped with an armature winding that generates induced electromotive force to act as a rotating magnetic field after being electrified The rotor rotates because the magnetic field generated by the stator interacts with the current in the rotor to produce electromagnetic torque to drive the rotor to rotate. The rotor punching sheet adopts high-speed multi-groove punching rotor core adopts centrifugal casting aluminum process.
Frame
The main function of the motor base is to fix the stator core and the front and rear end covers to support the rotor and play a role in protection and heat dissipation The motor base is an important part of the motor, and its functions include: Fixed stator core: The machine base is used to fix the stator core to ensure that it is stable and does not move or vibrate during the operation of the motor Support the rotor: The base supports the rotor through the front and rear end covers to ensure that the rotor can rotate smoothly without deviation or Protection and heat dissipation: The frame also plays a certain protective role to protect the internal structure of the motor from external influence At the same time, it also helps the motor to dissipate heat through the surface of the base to help the normal working temperature of the motor The frame plays an indispensable role in the working principle of the motor It is the basic part of the motor structure to ensure that the motor can run stably and efficiently In addition, the design and material selection of the machine base also have an important influence on the performance and life of the motor. Working procedures such as punching the end face of the inner hole of the milling foot lathe.
Final Assembly
Firstly, the iron core is fixed into the stator slot and an insulating material is injected to fix the iron core inside the stator slot. Then, the electromagnetic coil is wound on the stator slot and connected with the iron core. Then, install the rotor and rotor bearings, and finally install the end cover bracket and other components to complete the final assembly of the motor. This series of steps together constitute the basic production process of motor final assembly to ensure that the final product meets the design requirements.
