permanent magnet brushed dc motor

RK 520 DC Motor is a miniature brushed motor, output power: 2w; using brush commutation, the load torque can reach 1.23 mn.m, and it can be used at 1.5V-24V voltage. The specific rated voltage can be based on customer requirements Come for customized design, fine workmanship, stable welding, long service life, large torque, stable operation and high temperature resistance. The rotor uses pure copper windings and high-density molecular coating to effectively isolate dust. It is made of steel and has sufficient power and silent low speed. Product weight is about 41 g/1.45 ounces Product dimensions (length, width, height): 33*22.8*22.8mm/1.30*1.26*1.26 inches.

This is a small DC motor mainly used in toys, home appliances, vehicle equipment and other fields. Its working principle is based on the phenomenon of electromagnetic induction, which drives the motor to rotate through the interaction force generated by current in the magnetic field. Specifically, the motor is composed of permanent magnets and coils. The permanent magnets provide a static magnetic field, and the coils generate a dynamic magnetic field. When an external power source is applied to the coil, currents are generated inside the coil, and these currents create a magnetic field. Since the magnetic field in the coil and the magnetic field of the permanent magnet are in different directions, the two interact to cause the motor to rotate.

The 3V RF 520 motor has many great features. It is made of high-strength metal materials for durability and stability, and can withstand harsh conditions such as high temperature and pressure. This kind of motor also has the characteristics of high speed and high torque, which can complete high-intensity work tasks in a short time and improve production efficiency. In addition, it also has the advantages of low noise and low power consumption, will not cause interference to the working environment, and can save power costs.

The rotor of a small dc RK 520 motor mainly consists of an armature, brushes and collector rings. Among them, the armature is composed of windings and iron cores, and DC current is passed through the windings. When the armature is energized, it generates a magnetic field that interacts with the magnetic field of the permanent magnet to turn the motor. The brush rubs on the armature, causing the armature to continuously reverse. The collector ring is connected to the armature via brushes and carries the current back to the power source.

1. Raw material procurement: The main materials of mini DC motor include iron core, copper wire, magnet, etc. These materials need to be purchased from suppliers.

2. Processing and manufacturing: After the materials are purchased, they need to be processed and manufactured. The first is the processing of the iron core, which requires stamping, galvanizing, etc.; then the processing of the copper wire, which needs to be wound around the iron core to form the rotor and stator; and finally the processing of the magnet, which requires the magnet to be Installed on the motor.

3. Assembly test: After processing and manufacturing, the various components of the 520 DC motor can be assembled. After the assembly is completed, testing is required to ensure that the various indicators of the motor meet production requirements.
