Can servo actuators control asynchronous motors?
If it is to control the speed, torque accuracy is relatively high places there will be no ordinary motor, including electric spindle, you said the best way is to use servo motor. The main shaft is a high-speed motor, which is controlled by a transducer.
Stepper motor is the electrical pulse signal into angular displacement or line displacement of the stepper motor open-loop control yuan, in the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor, set the direction of a fixed Angle, known as the "step Angle", its rotation is based on the Angle of the fixed step by step. Can be controlled by controlling the pulse number of angular displacement, so as to achieve the purpose of accurate positioning, as well as by controlling the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of high speed. Servo motor is also called the execution, in the automatic control system, is used as actuators, the received electrical signal into angular displacement or angular velocity output of motor shaft
Can't, Ac servo motor is also a brushless motor. It is divided into synchronous and asynchronous motors The inside of the servo motor rotor is a permanent magnets, three-phase electric drive control of U/V/W form the electromagnetic field, under the action of rotating rotor in this field, at the same time, motor with encoder feedback signal to drive, drive according to the feedback value compared with the target, adjust the Angle of the rotor rotation. The accuracy of the servo motor is determined by the accuracy of the encoder (line count).
