Is the ac servo motor self internal speed control
A single servo motor can't work, but a servo controller can tune its own internal controls. General servo motor is the corresponding servo controller. Ac servo motor can be connected to the microcontroller, when the microcontroller will be sent to the motor speed value, servo motor will be done in its own internal speed, compare actual value with the given value and the rate of change in. A single servo motor can't work, and unlike the normal three-phase asynchronous motor, the power is turned. The servo controller is fitted with the servo motor system, the internal coder is a closed loop control, the speed is accurate, the torque is large and the resolution is high. The actuator input pulse, or the analog quantity, the serial port communication, can control the movement state of the servo motor. The frequency conversion is mainly the speed adjustment, while the servo is mainly position control.
Can be internal direct speed adjustment, use dot move speed pattern, normally use PLC to send the PLS pulse, also can use a single chip machine of course
Servo motor is not speed, is by the encoder, fanuc machine tool is done with the encoder is installed behind the bottom of the motor, removable, simple one, the other stator winding is your so-called exciting winding, three-phase electric have what problem, I don't understand
For example! The panasonic servo A4 series of electric motors has coders, encoders and motor positions. I didn't open it, I should have been an encoder! The encoder output is connected to the servo drive to control accuracy! When the encoder outputs the pulse signal! The servo actuator can be powered by a single unit and can also be powered by three.
