Brushless motor common four kinds of classification methods, you know it all

Brushless motors use circuit drive to replace the commutator of brushed motors, with a long service life, quiet, easy to control and other characteristics, often used in high-end automation control field. For the classification of brushless motor many friends still do not know very well, today to explain the classification of brushless motor it!

1. Distinguished by operating characteristics, they can be divided into DC brushless motors with DC motor characteristics and AC motor characteristics. Both are mainly powered by DC switching power supply. The main difference is that the former relies on position sensor to check a part of the motor rotor, while the latter converts DC power to AC power according to the inverter power supply.

2. Distinguished according to the drive method, they can be divided into square wave type DC brushless motors. The counter-electromotive force maintains a moderate phase difference correlation, resulting in a smoother electromagnetically induced torque.

3. Distinguished according to the motor rotor signal detection method, it can be divided into two types: position sensor and non-position sensor.

4. Distinguished by the appearance of the magnetic tile, it can be divided into two types: embedded and surface mounted, each containing many different types.

The above is the common classification of brushless motors, master these basic knowledge and content, in order to better understand the brushless motor.
