Classification of brushless motors

Brushless motor is a type of commutator that replaces electric brush motor with circuit drive, and has the advantages of long service life and convenient control. Widely used in high-end applications and automation control fields. So how to classify products? Let's take a look together.

1. According to the appearance of magnetic tiles, they can be divided into embedded and surface bonded types, each containing many different types, most of which are similar to rare earth permanent magnet motors.
2. According to the driving method, one type is the square wave brushless motor, in which the reverse potential difference of the motor itself is designed as a trapezoidal wave, and the inverter power supply outputs waveform current or operating voltage, which is related to the reverse potential difference of the motor and maintains a moderate phase difference, resulting in smoother electromagnetic induction torque.
3. According to the detection methods of motor rotor signals, they can be divided into two categories: position sensors and non position sensors. The former is limited in the application of brushless motors because some sensors are insufficient and susceptible to hazards such as temperature, dust, and vibration in office environments, while the latter eliminates the shortcomings of sensors and is therefore more widely used.
4. According to the characteristics of work, there are two types of brushless motors: one with DC motor characteristics and the other with communication and communication motor characteristics, both of which are powered by DC switching power supply systems. The difference is that the former relies on a position sensor to detect the position of the motor rotor, and uses the detected data signal to connect the opposite electronic device commutation power circuit, completing contactless commutation. The latter converts direct current into alternating current based on an inverter power supply, driving a general multi-threaded motor or electric motor.
The above is a classification explanation of brushless motors, which are usually used in the field of modeling due to their high control requirements and rapid development as a driving force. For more exciting content, you can visit other pages to continue viewing.
