With the advancement of industrialization, more and more factories are started using brushless dc motor controller, as a kind of highly efficient machinery and equipment, it brought great convenience to the production and operation. From the point of current machinery market, brushless dc motor controller is widely used in many fields, plays an irreplaceable role. Especially 100 dc motor controller was loved by many manufacturers, it has great advantage in the function effect, there is also a leading character in use. Let below small make up to analyze the causes of it has been widely used. First of all, the brushless dc motor controller has more rich than the general motor controller utility, it not only has the normal operation of the motor controller performance, and on this basis, it also improved the function of ordinary motor controller failure, and have a good start. It also has a long service life, high reliability characteristics. In addition, it is usually used for the permanent magnet rotor, no excitation loss; Fever of armature winding and is usually served on the outside of the stator, in this way, the thermal resistance is small, heat easily. So no commutation spark, brushless dc motor controller without radio interference, easy maintenance. On the other hand, in the specific operation, brushless dc motor controller also has obvious advantage on the operation efficiency. It has a quick operation on the basis of also sped up the process of power supply, for the whole operation process provides a steady stream of power supply. Its speed is not restricted by the mechanical commutation, if use air bearing or magnetic suspension bearing, can run in the speed of up to hundreds of thousands of revolutions per minute. Because of the brushless dc motor controller has the above a series of advantages, therefore, its application far widely. To sum up, the brushless dc motor controller is used so widely, not only because of its excellent function, also is that it has more significant than ordinary motor controller of the production efficiency.
