Motor type detailed interpretation
the motor controller refers to according to the law of electromagnetic induction motor controller to realize energy conversion or transfer of an electromagnetic device. Motor is also commonly known as the motor) In the circuit with the letter 'M' ( The old standard with a 'D') Said. Its main function is to produce drive torque, as with all electrical or mechanical power. Generator controller in a circuit with the letter 'G'. Its main function is to use mechanical energy into electrical energy. According to the working power supply varieties division: can be divided into dc motor controller in ac motor controller. According to the working power supply varieties division: can be divided into dc motor controller and ac motor controller. Dc motor according to the principle of work can be divided into: brushless dc motor and brushless dc motor. Dc motor according to the principle of work can be divided into: brushless dc motor and brushless dc motor. The ac motor controller also can be divided into: single phase motor controller and the controller of three-phase motor ac motor controller also can be divided into: single phase motor controller and the controller of three-phase motor. According to the structure and working principle of the division: can be divided into dc motor, ac) Asynchronous motor, according to the structure and working principle of the division: can be divided into direct current motor, asynchronous motor, control motor divided again: stepping motor and servo motor, etc. Therefore, the linear displacement or angular displacement is proportional to the pulse number; According to the movement mode can be divided into rotary motion, such as straight line and plane motion; Asynchronous motor rotor speed is always less than synchronous speed of the rotating magnetic field. Synchronous motor rotor speed has nothing to do with the size of the load and always stay for the synchronous speed. Brushless dc motor 1. Brushless dc motor controller dc motor controller has the advantages of rapid response, large starting torque, rotating speed of from zero to rated speed can provide the rated torque performance, but the advantages of dc motor controller is also its drawback, because the dc motor controller to produce a constant torque under the rated load performance, the armature magnetic field maintain 90 ° with the rotor magnetic field to be constant, this is about to borrow from the carbon brush and commutator. Carbon brush and commutator motor controller rotational motion produced sparks, carbon powder, so besides can cause damage of components, its usage is restricted. Ac motor controller without carbon brush and commutator, free maintenance, strong, wide application, but if you want to achieve the equivalent of dc motor controller according to the characteristic of performance must use complex control technology to achieve. 2. Brushless dc motor controller the control structure of brushless dc motor controller is synchronous motor controller of a 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 dc motor controller, sexual way. That is to say, brushless dc motor controller can be within the rated load when the load changes can still control rotor motor controller to maintain a certain speed.
