Fifth, bearings and shaft tiles.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
The insulation sleeve of the motor accessories is complete without cracks and no loose phenomenon. Lead wire connection should be solid, insulation resistance value should not be less than 0.5MΩ at working temperature 75℃. in brush device, the lower edge of the brush box is required to be 2~4mm away from the surface of the motor accessories, the distance is too large will cause the brush to jump in the brush box, if it is hard brush, it is likely to break.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
Brush in the brush box should slide flexible, brush box hole surface smooth, brush box hole diameter to size tolerance of H10, axial size tolerance of H8. brush width and thickness size tolerance d11. brush and brush box wall clearance should be 0.1 ~ 0.2mm, gap is too large, brush in the brush box tangential oscillation, affecting the normal work of the motor accessories; gap is too small, so that the brush stuck in the brush box, resulting in similar The arc of welding burns the surface of copper ring.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/

Inspection of the motor parts should be carried out carefully: whether the working surface of the motor parts type is smooth, and whether there are defects such as burn marks and strip marks. The working surface is required to be smooth, and there should be no rust and grease. Motor accessories insulation external binding should be correct and well coated. If not well handled, synthetic resin-impregnated weft-free glass ribbon can be used to tie the motor to prevent the external leakage of mica flakes from flying apart when the motor is running. Motor parts and shaft fit and each ring and insulation sleeve fit should be solid, with a small hammer lightly knock the copper ring and set of copper fit, there should be metal sound.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/

Brush and ring contact should be close. The pressure difference between the brushes should not exceed 20% of its average value. There is a brush lifting device winding rotor asynchronous motor, short circuit ring on the contact with the motor accessories on the blade even contact, contact area of 60% or more, to avoid causing the rotor single-phase operation or contact overheating loss of flexibility. For the motor accessories surface slight burn marks, pockmarks, brush marks and other defects, available oil stone, fine file grinding, and finally use zero zero zero abrasive cloth to beat light. In general, should not be easy to turn the motor parts, because turning once will reduce a lot of life.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
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 blade, bearing and other parts.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/

Motor stator.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
The motor stator is an important part of motors such as generators and starters. The stator is an important part of the motor. The stator is composed of stator core, stator winding and seat. The main function of the stator is to produce a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic lines in the rotating magnetic field to produce (output) current. China's current motor parts market is distributed in the southeast coast and the Yangtze River Delta region. In particular, there are relatively more manufacturers producing motor parts in Jiangsu, Zhejiang, Shanghai and Guangdong Province. Among them, there is no lack of some well-known and strong auto motor parts stamping and drawing manufacturers.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/

Motor rotor.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
Motor rotor: It is also the rotating part in the motor. The motor is composed of two parts: rotor and stator, which is used to realize the conversion device of electric energy and mechanical energy and mechanical energy and electric energy. Motor rotor is divided into motor rotor and generator rotor.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/

Stator winding.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
The stator winding can be divided into two categories: centralized and distributed, depending on the shape of the coil winding and the embedded wiring method. Centralized winding is simpler in winding and mounting, but the efficiency is lower and the running performance is poor. At present, most of the AC motor stators are applied with distributed winding. According to different models, types and coil winding process conditions, the motors are designed with different winding types and specifications, so the technical parameters of the windings are different.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
Motor housing.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/

Motor housing generally refers to the external housing of all electrical motor equipment. The motor housing is the protection device of the motor, which is made of silicon steel and other materials by stamping and deep drawing process. Plus the surface of the anti-rust and plastic spraying and other processes can be a good protection of the motor internal equipment. The main role: dust-proof, noise-proof, waterproof.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/

End coverSourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
End cover (Cover), is a back cover installed in the back of the motor and other housings, commonly known as "end cover". According to the 2015-2020 Internet + end cover processing machine industry operation mode research and consulting reportSourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
Cover is mainly composed of cover body, bearing and brush piece.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
End cover (Cover) is good or bad, directly affects the quality of the motor motor. Therefore, we first need to understand what is meant by a good or bad standard of end cover. A good end cover, mainly from its heart - brush piece, its role is to drive the rotation of the rotor, this part is the most critical part, then how do we measure its good or bad? It mainly has the following criteria.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/

Bearings.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
Bearing (Bearing) is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotary accuracy.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
According to the different frictional properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings its radial size, vibration and noise are larger, and the price is also higher.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
Rolling bearings are generally composed of outer ring, inner ring, rolling body and cage four parts, strictly speaking by the outer ring, inner ring, rolling body, cage, seal, lubricant six major components. 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.SourceRare earth magnet-https://www.rare-earthmagnet.com/motor-accessories-classification/
