Is it better to use brushless motor with hall or without hall?

Hall type is to judge the current state of motor movement through the signal sent by the hall element of the motor, and then the controller controls the output of the controller according to the signal collected by hall to supply power to the motor, so that the motor can continue to work normally. Hall sensor can detect the position of the rotor, and the motor starts smoothly.

The hall free type is a motor without Hall sensor. The controller judges the current motion state of the motor through current collection, and then controls the output of the controller to supply power to the motor, so that the motor can compete for production.

effect:

Hall type brushless motor and controller are stable in use, with large torque and no abnormal noise when starting.

Hall less brushless motor and controller are not very stable at present due to scientific and technological problems, especially in the initial stage, with poor stability and insufficient power.

Hall brushless motor is a relatively mature scheme at present, and its operation is more stable. However, the hall element is a burned out part of the container, so it is particularly important to select the appropriate manufacturer and qualified Hall element. In the market, there are often undesirable businesses that use class C or even class D Hall components to replace labels and pretend to be class B or class a Hall components, which ultimately affects the quality qualification rate; Therefore, it is particularly important to stabilize long-term cooperative Hall component suppliers, and do not change suppliers casually because of the low unit price. Brushless motor driven by hall less can be used in occasions where the requirements for motor operation pipeline are not high.
