Structural composition of discount 230v dc motor stator
DC motor is a kind of motor product that is widely used in daily life. In DC motor, there is a concept called stator. What is the stator of DC motor? What is the structure of the stator? Shenzhen Longhui Motor introduces you in detail:
The stator structure of the DC motor:
1. Brush device: The brush device of the DC motor is used to introduce or draw DC voltage and DC current. The brush device is composed of a brush, a brush holder, a brush bar and a brush bar holder.
2. Reversing pole: The function of the commutating pole is to improve the commutation and reduce the reversing spark that may be generated between the brush and the commutator during the running of the motor. Generally, it is installed between two adjacent main poles. The pole core and the commutating pole winding are formed, and the commutating pole winding is wound with an insulated wire, and is placed on the commutating pole core, and the number of commutating poles is equal to the main pole.
3. Base: The outer casing of the DC motor stator is called the machine base. The function of the base is two: one is to fix the main magnetic pole, the commutating pole and the end cover, and to support and fix the whole DC motor; It is the base itself that is also part of the magnetic circuit, whereby the magnetic path between the magnetic poles is formed, and the portion through which the magnetic flux passes is called a yoke.
4. Main magnetic pole: The main magnetic pole acts to generate an air gap magnetic field. The main magnetic pole is composed of a main magnetic pole core and a field winding.
