Introduction to the choice of dc motor controller

Many users in the dc motor controller, will consider what kind of dc motor controller is efficient? Below small make up a simple. When the choice, can according to the requirement of load, considering its working conditions, load properties, production technology, the power supply situation and so on factors, the mechanical properties to meet it. Motor type to the mechanical characteristic of the dc motor controller and the mechanical properties of mechanical work, so should choose appropriate, to ensure its high speed, speed rate, steady speed, speed, speed, such as performance, to adapt to the working of mechanical operation requirements. Above all, you know how to choose the dc motor controller?
