Brushless dc motor controller is a kind of synchronous motor controller

brushless dc motor controller is a kind of synchronous motor controller, the rotor speed of the motor controller that is motor controller speed rotating magnetic field of the stator and rotor pole ( P) Effect: N = 120. f / P。 In case the number of rotor fixed, change the frequency of the stator rotating magnetic field can change the speed of the rotor. Brushless dc motor controller is the synchronous motor controller combined with electronic control ( Drive) , control the frequency of the stator rotating magnetic field and the motor controller of rotor speed feedback to the control center again, in order to achieve close to the brushless dc motor controller features. That is brushless dc motor controller can be within the rated load when the load changes can still maintain control motor controller rotor speed. Brushless dc drives including power department and control department as shown in figure ( 1) : power supply provides the three-phase power supply to the motor controller, control of the transformation input power frequency in accordance with the requirements. In case the number of rotor fixed, change the frequency of the stator rotating magnetic field can change the speed of the rotor. Brushless dc motor controller is the synchronous motor controller combined with electronic control ( Drive) , control the frequency of the stator rotating magnetic field and the motor controller of rotor speed feedback to the control center again, in order to approach to achieve dc motor controller features. That is brushless dc motor controller can be within the rated load when the load changes can still maintain control motor controller rotor speed. http://www。 tcmotor。 Com foshan electrical and mechanical equipment co. , LTD. , brushless motor controller, brushless dc motor controller, dc servo motor controller, planetary reducer, brushless drive, electrical and mechanical, foshan electrical and mechanical equipment co. , LTD
