There are the main advantage of the brushless dc motor control is simple, mature technology. Ac motor controller are far superior to the control characteristics. On the early development of electric vehicles use dc motor more, even now, there are some electric cars still use dc motor to drive. But due to mechanical brush and commutator, not only limits the further improve motor overload capacity and speed controller, and if the long run, is bound to regular maintenance and replacement brush and commutator. In addition, due to the loss in the rotor, make it easier for heat dissipation, limit the torque motor controller for improving the mass ratio. In view of the dc motor defects above, in the new development of electric cars has been basically do not use dc motor. Brushless dc motor controller is a kind of high performance speed reducer. Its characteristic is the external characteristic of dc speed reducer without mechanical contact structure composed of brush. In addition, it USES permanent magnet rotor, no excitation loss: fever and installed on the outside of the stator, armature winding heat easily, therefore, no commutation spark, brushless dc motor controller without radio interference, long service life, reliable operation, easy maintenance. In addition, its speed is not affected by the limitation of mechanical commutation, if use air bearing or magnetic levitation bearing, can run at up to hundreds of thousands of revolutions per minute. Brushless dc motor controller machine system compared with higher energy density and higher efficiency, and has a good application prospect. The proud technology adhere to the customer demand as the center, continuous improvement, to provide economic and reliable power transmission scheme. Let science and technology into productivity, our purpose is to create value for society and enterprises. When you need for your system to choose a good driving scheme, please choose us, when you find your design ideas not embodied in this book, please contact our application engineer team, we are looking forward to your inquiry.
