Dc motor speed control method of sharing controller

by:Hoprio     2020-07-25
In dc motor controller in the process of running, sometimes the need for speed, then you know it has several speed regulating methods? 1. Armature resistance speed: different types of dc motor controller can be this way. When the load reaches a certain standard, due to resistance of the dc motor controller, the armature loop total resistance increases, thus reduce speed appears. 2. Change the armature voltage control: voltage there are two ways: one is to use change voltage; The second is to use the thyristor inverter power supply control system. 3. Change the field current speed: when the armature voltage constant, choose field current to achieve speed control. Above is the dc motor speed control method of the controller, hope to help you.
