Brushless dc motor controller is to direct current (dc) can be converted into mechanical energy or converting mechanical energy into direct current to the rotation of the motor controller, sometimes at the time of use, need speed, speed regulation method what then? 1. Change the armature loop resistance speed control of dc motor controller can be speed by changing the armature loop resistance, when the load must be as the series of the external resistance increases, the armature loop total resistance increases, motor speed is reduced. The change of the external resistance available contactor switch to implement or master. 2. Change the armature voltage regulating continuous armature voltage, can make the dc motor controller in a very wide range realize stepless speed regulation. Change the armature voltage method has two kinds, one kind is the generator controller -Electric power supply of the speed regulation system; Another is to use the thyristor inverter power supply control system. 3. Change the field current speed when the armature voltage constant, change the excitation current of dc motor controller can realize speed regulation. Mastery of the dc motor speed control method of the controller, the use of the product is good for the future, to know more about the knowledge of the motor controller at the same time, we later use, you can make it play a better effect.
