The classification of motor parts can be classified according to the components of the motor, which can be divided into motor stator, motor rotor, stator winding, motor shell, end cover, motor fan blade, bearing and other parts.
The motor stator is an important part of the generator and starter motor. The stator is an important part of the motor. The stator consists of stator core, stator winding and a three part. The main function of the stator is to produce a rotating magnetic field, and the main function of the rotor is to cut the magnetic field line in the rotating magnetic field, and then to produce (output) current. Currently electrical accessories accessories market distribution along the southeast coast and the Yangtze River Delta in china. Especially Jiangsu Zhejiang Shanghai and Guangdong Guangdong area, the production of electrical accessories manufacturers is relatively large. There are some famous and powerful motor vehicle parts stamping drawing factory.
The motor rotor is: rotating parts of motor. The motor consists of two parts, rotor and stator, which is used to realize the conversion between electrical energy and mechanical energy, mechanical energy and electrical energy. The motor rotor consists of motor rotor and generator rotor.
The stator winding can be divided into two types: centralized and distributed according to the shape of the winding and the way of embedding and wiring. The winding and inlay of the centralized winding is relatively simple, but the efficiency is low and the operation performance is poor. AC motor stator current is mostly distributed windings, according to different models, models and process conditions around the coil block, each motor design using different winding type and specifications, technical parameters of the windings are not the same
The outer shell of motor shell generally refers to all electrical equipment. The motor shell is the protector of the motor, and the silicon steel sheet and other materials are made by stamping and drawing process. To protect the motor internal equipment good surface treatment and spray process with rust. Main functions: dustproof, anti noise and waterproof.
According to the material to points can be divided into: the shell metal casing, a plastic shell.
Purpose: according to the starter generator shell, shell, motor shell and other digital products
The end cover, a rear cover is installed in the back casing of the motor end cover, commonly known as "". Is mainly composed of a cover body, bearing, brush plate. The cover is good or bad, directly affect the quality of the motor. Therefore, we must first understand what is called, a cover of the quality standards. A good cover, it is mainly from the heart of the brush, it is driven by the rotation of the rotor, this part is the key part of it, how can we measure it good or bad? It mainly has the following several criteria:
1, not high.
2, not low.
3, not short.
4, no fork.
5, no bending.
6, not Qu.
The motor fan blade is usually at the tail of the motor, which is used as the ventilation and cooling of the motor, mainly Acting on the tail of the AC motor, or placed in the special ventilation pipe of the DC and high-voltage motor. The fan blade explosion-proof motor general plastic material.
According to the material classification: the motor fan blade can be divided into three kinds, and plastic wind blade, cast aluminum fan blade, cast iron fan blade.
Bearing (Bearing) is one of the most important parts in modern mechanical equipment. Its main function is to support the rotating body of the machine, reduce the friction coefficient in the process of movement, and ensure its rotation accuracy.
According to the friction property of the moving element, the bearing can be divided into two categories: rolling bearing and sliding bearing. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial size, vibration and noise are larger, and the price is higher.
Generally, the rolling bearing consists of four parts: outer ring, inner ring, rolling body and cage. It is composed of six parts: outer ring, inner ring, rolling body, cage, seal and lubricating oil. Mainly with the outer ring, inner ring and rolling element can be determined for rolling bearings. According to the shape of rolling, rolling bearing for ball bearings and roller bearings two categories.
