Say to brushless dc gear motor controller everyone reaction is the price is higher, so why now most medium enterprises gradually from a choose motor controller into the brushless motor controller? High capital cost would do such a choice? Let's discuss brushless dc gear motor controller what are the advantages? 1, brushless dc motor speed controller is of high reliability due to the brushless dc motor controller is the evolution of the brush motor controller products, its working principle is to use electronic commutation to replace the brush brush commutation motor controller, so there is no due to mechanical commutation spark of problems, and can be high speed, because they don't need regular replacement of carbon brush, so that the reliability of the motor controller will be higher, protective performance is better, suitable for a variety of working conditions. 2, brushless dc gear motor, controller of the wide scope of speed control of dc brushless motor controller does not exist a low-speed large current problem of carbon brush pressure drop, and can be in normal operation, low speed high current speed can reach tens of thousands of r, than have a motor controller, the runtime to commutation spark, high speed limit is low, when running in low speed large current, brush pressure drop is bigger, not suitable for long time running. 3, brushless dc gear motor controller with high efficiency has a brush motor controller with and brush, increased the losses in the motor controller, motor controller with natural reduces the efficiency, but there is a rotor brushless motor controller on the magnetic steel to build motor controller main magnetic field, so that more save energy, the efficiency is high. 4, brushless dc gear motor, the power density of the controller is a collector ring brush brush motor controller, the effective volume occupies the motor controller, the controller of the power density is small, so the motor rotor brushless motor controller is current, the motor controller low fever, smaller volume can produce larger power, motor controller output per unit volume is big, big motor controller power density. 5, brushless dc gear motor, controller of low noise due to the brushless motor controller without brush, less friction force during operation, smooth running, will reduce a lot of noise. Brushless dc gear motor controller and the characteristics of wide use range, service life is long, can reach tens of thousands of hours, brushless motor controller is a digital frequency conversion control, strong controllability, from several to tens of thousands of revolutions per minute per minute can be implemented. Above these advantages is the reason why most manufacturers choose brushless motor controller, comprehensive above clearly choose brushless motor controller price will be higher than a brush motor controller, so you picked the right motor controller?
