Control mechanism of brushless DC motor

It is an open loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the motor speed, stop position only depends on the pulse signal frequency and pulse number, and is not affected by load changes, that is, to add a pulse signal to the motor, the motor is turned around a step Angle.

It is an open loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the motor speed and stop position only depend on the frequency and number of pulse signals, and is not affected by load changes, that is, to add a pulse signal to the motor, the servo motor will turn a step Angle. The existence of this linear relationship, coupled with the motor only periodic error without cumulative error and so on. The speed, position and other control areas with motor control becomes very simple.

The existence of this linear relationship, coupled with the motor only periodic error without cumulative error and so on. The speed, position and other control areas with motor control becomes very simple. Although the motor has been widely used, but the motor is not like ordinary DC motor.

When the driver receives a pulse signal, it drives the motor to rotate at a fixed Angle in a set direction. The angular displacement can be controlled by controlling the number of pulses so as to achieve the purpose of accurate positioning. At the same time, the speed and acceleration of motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation.
