What's the difference between a variable frequency motor and a servo motor?
Then it is servo motor, variable frequency motor and the main difference with the encoder, and then transmitted to the servo motor drive, and then using the control theory, such as gain, adjust time, simply say a servo motor is a closed-loop control system, and quick start, stop, load capacity a variable frequency motor, with these characteristics, also makes the speed, torque, third position control method for high requirement application. 1, servo motor and inverter and working principle of AC motor is basically the same, belong to the AC-DC-AC voltage type motor drive, but the technical requirements of big differences, so there are great differences in the aspects of motor and driver design.
