DC brushless geared motor is the integrated body of geared motor and DC brushless motor (motor). Usually by the professional motor production plant, integrated and assembled, and the motor as a whole set of supply.
According to the actual needs of customers' products, we can provide miniature reducer, worm gear reducer and other products. To provide customers with a full set of DC brushless geared motor solutions, products with low noise, small size, high efficiency, low energy consumption and other characteristics. Among them, what are the control methods of DC brushless geared motor, the following is a brief introduction for you.
1、Speed control
DC brushless geared motor speed control can be achieved by changing the size of the voltage, there are two commonly used methods: one is to keep each phase conduction time unchanged. Change the magnitude of the voltage added to the coil when each phase is on to achieve speed regulation, the other is to keep the voltage magnitude constant, change the length of each phase on time to achieve speed regulation.
2、Microcomputer control
DC brushless gear motor is created and developed along with digital control technology, so the digital control of DC brushless motor by microcomputer is the main control means.
3、Forward and reverse control
Because the DC brushless geared motor is very different from DC motor in structure. So it can't use the method of changing the power supply nature to change the steering, but can only change the rotation direction by changing the relative relationship between the stator winding magnetic potential and the rotor magnetic field. The control method is to use two mutually differing harness signals in phase to control the corresponding winding conduction, so as to achieve forward and reverse rotation. Electronic circuits can also be used to perform certain logic processing to obtain a positive and a negative signal.
