Why should a magnet be added to the reducer rotor?

Addtime:2022-08-16 14:42:20 Click:258

Structurally, both the brushed DC geared motor and the brushless DC geared motor have a rotor and a stator. I will not introduce too much about the difference between these two types today. There are many related introductions on the Internet. Today's content mainly talks about the reducer. Why do the rotors need magnets?


To make the reducer rotate, first the control unit needs to sense the current position of the motor rotor, and then according to the stator winding to determine the order of turning on the power transistors in the inverter, so that the current flows through the motor coil in sequence to generate a forward rotating magnetic field , and interacts with the magnet of the rotor, so that the motor can be rotated clockwise/counterclockwise. The performance of the DC gear motor is related to the number of permanent magnets, the magnetic flux intensity, and the input voltage, which is also very important to the control performance. relation.

Motor rotor magnet

For example, the brushless DC gear motor relies on changing the alternating frequency and waveform of the current wave input to the stator coil. A magnetic field that rotates around the geometric axis of the DC gear motor is formed around the winding coil, and the magnetic field drives the permanent magnet on the rotor to rotate. The DC motor starts to rotate, and the performance of the DC gear motor is related to the number of permanent magnets and the magnetic flux intensity.


Guess your concern: what is the material of the reducer magnet?

The common types of magnets for miniature geared motors are ferrite magnets and NdFeB magnets.


The above is the introduction of why magnets are added to the reducer rotor and the magnet material. If you need to purchase motor-related magnets, you can contact our company to provide you with samples and evaluate the price.
