Classification of motor parts


Classification of motor parts may be classified according to the components of the motor, can be divided into motor stator, motor rotor, stator winding, motor shell, end cover, motor fan blades, bearings and other components.

Electronic motor

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 stator's main function is to produce a rotating magnetic field, and the main function of the rotor is in a rotating magnetic field generated by magnetic lines cutting and current (output). China's current motor accessories market distribution in the southeast coast and the Yangtze River Delta region. Especially Jiangsu Zhejiang Shanghai and Guangdong Guangdong area, the production of electrical accessories manufacturers is relatively large. Some of them are well-known and have the strength of motor vehicle parts stamping drawing factory.

Motor rotor

Motor rotor: is also the rotating part of the motor. The motor is composed of two parts, the rotor and the stator, and the utility model is used for realizing the conversion device of the electric energy and the mechanical energy and the mechanical energy and the electric energy. The motor rotor is divided into motor rotor and generator rotor.

stator winding

The stator winding can be divided into two types: centralized and distributed according to the shape of coil winding and the way of embedded wiring. Centralized winding winding and embedding is relatively simple, but the efficiency is low, poor operating performance. 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

Motor housing

The outer shell of motor shell generally refers to all electrical equipment. The motor case is the protection device of the electric motor, which is made of silicon steel sheet and other materials. To protect the motor internal equipment good surface treatment and spray process with rust. Main functions: dustproof, anti noise, waterproof.

According to the material can be divided into: shell can be divided into metal shell, plastic shell, etc..

Purpose: according to the starter generator shell, shell, motor shell and other digital products

Motor end cover

End cover (Cover), is installed in the back of the motor, such as a rear cover, commonly known as "end cover". According to the [4] machine tool industry business model research report Internet plus 2015-2020 end cap

The end cover (Cover) is mainly composed of a cover body, a bearing and an electric brush sheet.

The end cover (Cover) is good or bad, directly affects the motor motor quality. Therefore, we must first understand what is called a good or bad end cover 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, is not high.

2, is not low.

3, not short.

4, no fork.

5, not bending.

6, no song.

Generator wind blade

The motor fan blade is usually in the tail of the motor, which is used for the cooling and cooling of the motor. It is mainly used in the tail of the AC motor, or in the special ventilation pipe of the DC motor and the high voltage motor. Explosion proof motor fan generally use plastic material.

According to the material classification: the motor fan can be divided into three types, and a plastic fan blade, aluminum, cast iron fan blades.

Bearing (Bearing) is one of the most important parts in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient in the process of movement, and to ensure its rotation accuracy.

According to the friction properties of the different components, bearings can be divided into two categories: rolling bearings and sliding bearings. Rolling bearing has been standardized, serialized, but compared with the sliding bearing radial size, vibration and noise, the price is higher.

Rolling bearing is generally composed of four parts: outer ring, inner ring, rolling body and cage. It is strictly composed of outer ring, inner ring, rolling body, cage, seal and lubricating oil. It is composed of six parts. Mainly with the outer ring, inner ring, rolling body can be defined as rolling bearings. According to the shape of the rolling body, rolling bearings are divided into two categories: ball bearings and roller bearings.
