DC brushless motor refers to the rotating motor that can convert electromagnetic energy into mechanical kinetic energy or mechanical kinetic energy into electromagnetic energy. When we are in application, we often speed the motor. What is the speed change method of the motor?
1. Change the resistor of the power supply circuit to start the speed change
All kinds of DC brushless motors can change speed according to the resistor of the control loop of the synchronous motor. When the load is constant, with the expansion of the external resistor in series, the total resistor of the control loop of the synchronous motor expands, and the speed ratio of the motor will decrease. Changes to the external resistor may be made by alternating current contactor or by switching the main switch.
2. Change the working voltage of the power supply circuit
Constantly change the working standard voltage of the power supply and distribution system of the brushless DC motor, which enables the brushless DC motor to speed stepless in a wide range. There are two ways to change the working standard voltage of the power supply and distribution system of brushless DC motor, one is to use the variable speed system software of the power supply and distribution system of generator set and motor set, the other is to use the variable speed system software of the power supply system of bidirectional thyristor converter.
3. Change the current of the power circuit to change the speed
When the working standard voltage of the brushless DC motor is certain, even if the total electric flow of the DC brushless DC motor can also be adjusted.
Masted DC brushless DC motor speed change method, the use of future goods is good, in addition to grasp more – some professional skills related to the motor, we in the second half of the use, can make full use of the greater effect of the motor.
