The Basic Structure Of The Micro DC Motor Of The Beauty Instrument
Leave a message
DC micro-motors are very common in beauty equipment. It can convert the electrical energy of DC motors into mechanical energy. It has excellent starting characteristics and speed regulation performance, large torque and high cost performance. Therefore, the application of DC micro-motors in beauty equipment is very widely. The structure of an ordinary motor consists of a stator, a rotor and an end cover. What is the structure of a DC micromotor for beauty instruments?
Motor stator:
1. The main magnetic pole is composed of the iron core of the main magnetic stage and the excitation winding. The excitation winding passes current and generates the main magnetic field. The lower part of the magnetic pole is called the pole palm. The function of the main magnetic pole is to generate magnetic flux in the air to make the excitation winding firmly fixed in the On the iron core, the magnetic poles on the surface are part of the magnetic circuit, which is made of laminated steel plates, and the excitation windings are wound with insulated copper wires.
2. Commutation pole: used to improve the commutation characteristics of the armature current, fixed at the center of the main magnetic pole of the stator with a screw
3. Brush device: the brush is installed on the stator and keeps sliding contact with the brush and the commutator, so that the armature winding is connected to the external current
4. Machine base: used to fix the main magnetic pole, commutator and end cover.
motor rotor
1. Armature core: Its main function is to provide armature windings and magnetic flux to reduce eddy current loss and hysteresis loss in the armature core when the motor is running.
2. Armature part: its main function is to convert electromagnetic torque and induced electromotive force energy (the armature winding is composed of many coils);
3. Commutator: Also known as commutator, the main function of the beauty instrument micro-motor is to convert the DC power from the brush into current to the armature winding.
