The operation efficiency of the motor directly affect the efficiency of electricity and also influence the rise of temperature of the motor itself. It is one of the important indicators of quality of motor. Therefore, all kinds of motor rated runtime efficiency has specific provisions in the relevant technical conditions, and sometimes regulation efficiency of tolerance. When a motor is designed to ensure the efficiency of regulation. Due to the current application of brushless dc motor power are smaller, its energy consumption index is not very outstanding, in guarantee under the premise of other performance indicators, sometimes allowed to sacrifice some efficiency. for more details, please log on to http://www. hengdrive。 Com 2012 - motor controller co. , LTD9 -14 the Chinese first-class enterprise brushless dc motor controller, creating common, standard the full range of brushless dc motor controller the motor controller.
