The classification of motor accessories can be roughly based on the components of the motor, including the motor stator, motor rotor, stator winding, motor housing, end cover, motor fan blades, bearings, and other parts
Motor stator:
The stator of a motor is an important component of motors such as generators and starters. The stator is an important part of an electric motor. The stator consists of three parts: the stator core, the stator winding, and the machine base. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic field lines in the rotating magnetic field and generate (output) current. At present, the market for motor parts and accessories in China is distributed along the southeast coast and the Yangtze River Delta region. Especially in the Jiangsu Zhejiang Shanghai and Guangdong Guangdong regions, there are relatively more manufacturers producing motor parts. Among them, there are some well-known and powerful automotive motor parts stamping and deep drawing manufacturers
Motor rotor:
Motor rotor: It is also a rotating component in the motor. An electric motor consists of a rotor and a stator, which are used to convert electrical energy into mechanical energy and mechanical energy into electrical energy. Motor rotors are divided into motor rotors and generator rotors
Stator winding:
The stator winding can be divided into centralized and distributed types according to the shape of the coil winding and the embedded wiring method. The winding and embedding of centralized windings are relatively simple, but their efficiency is low and their operational performance is poor. At present, the vast majority of AC motor stators use distributed windings. According to different models, models, and coil embedding process conditions, motors are designed with different winding types and specifications, so the technical parameters of their windings are also different
Motor casing:
The motor casing generally refers to the external casing of all electrical and motor equipment. The motor casing is a protective device for the motor, made of silicon steel sheets and other materials using stamping and deep drawing processes. Adding surface rust prevention and spray coating can effectively protect the internal equipment of the motor. Main functions: dustproof, noise proof, waterproof.
Classified by material: The shell can be divided into metal shell, plastic shell, etc
Classified by purpose: generator casing, starter casing, other digital product motor casing
Motor fan blades:
The fan blades of the motor are generally located at the tail of the motor, used for ventilation and cooling of the motor. They are mainly used at the tail of the AC motor or placed in the ventilation ducts specially designed for DC and high-voltage motors. The fan blades of explosion-proof motors are generally made of plastic material
According to material classification, motor blades can be divided into three types: plastic blades, cast aluminum blades, and cast iron blades
Bearing:
Bearing is an important component in contemporary mechanical equipment. Its main function is to support mechanical rotating bodies, reduce their friction coefficient during motion, and ensure their rotational accuracy
According to the different friction properties of moving components, bearings can be divided into two categories: rolling bearings and sliding bearings. Rolling bearings have been standardized and serialized, but compared to sliding bearings, they have larger radial dimensions, vibration, and noise, and are also more expensive
Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements, and cage. Strictly speaking, they consist of six major components: outer ring, inner ring, rolling elements, cage, seal, and lubricating oil. A rolling bearing can be defined as having an outer ring, an inner ring, and rolling elements. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings
