What are the motor accessories

Motor parts

　　Motor accessories refers to the motor manufacturer to assemble the motor parts for the original motor parts, due to improper use or wear caused by damage to the replacement parts called motor accessories. General accessories life is not as long as the original life.

　　What are the motor accessories

1, motor stator

　　Motor stator is an important part of the motor such as generator and starter. Stator is an important part of the motor. The stator is composed of stator core, stator winding and seat. The main role of the stator is to produce a rotating magnetic field, while the main role of the rotor is to be cut by the magnetic lines in the rotating magnetic field to produce (output) current.

　　2, motor rotor

　　Motor rotor is also the rotating part of 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.

　　3、Stator winding

　　Stator winding can be divided into centralized and distributed according to the shape of coil winding and embedded wiring. 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.

　　4、Housing of motor

　　Motor shell generally refers to the external casing of all electrical motor equipment. The motor shell is the protection device of the motor and is made of silicon steel and other materials with stamping and deep drawing process. Plus the surface of the anti-rust and plastic spraying and other technological processing can well protect the motor internal equipment. The main role: dustproof, noise-proof, waterproof.

　　5、End cover

　　End cover is installed in the motor and other housing behind a back cover, commonly known as "end cover", mainly by the cover body, bearings, brush piece. End cover is good or bad, directly affects the quality of the motor motor. 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.

　　6, motor air blade

　　Motor air blade is generally at the end of the motor, used for ventilation and cooling of the motor, mainly in the AC motor tail, or placed within the DC, high voltage motor special ventilation duct. Explosion-proof motor blades are generally made of plastic.

　　According to the material classification: motor airfoil can be divided into three, and plastic airfoil, cast aluminum airfoil, cast iron airfoil.

　　7、Bearing

　　Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce its friction coefficient in the process of movement, and to ensure its rotary accuracy.

　　Rolling bearing is 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.
