Mitsubishi servo motor is an AC permanent magnet servo motor developed by Mitsubishi Company. The following will introduce its working principle, classification, characteristics and application scenarios:
Working principle: Servo systems generally consist of servo amplifiers and servo motors. The rotor inside the servo motor is a permanent magnet. The U/V/W three-phase electricity controlled by the servo amplifier forms an electromagnetic field. The rotor rotates under the action of this magnetic field. At the same time, the encoder of the motor feeds back a signal to the driver. The driver adjusts the feedback value according to the feedback value. Compare with the target value and adjust the rotor rotation angle.
Classification
MR-J series: including MR-J, MR-J2, MR-J2S, MR-J3, MR-J4 and other sub-series. For example, the MR-J3 series has USB and RS-422 serial communication functions. The matching high-performance servo motor encoder has high resolution, fast speed loop frequency response, and high-speed/large torque characteristics.
MR-H series: usually has high performance and reliability, and is suitable for some occasions with higher requirements on motors.
MR-C series: It shows good adaptability in some specific application scenarios and can meet some more special control needs.
MR-E series: Developed on the basis of the MR-J2S series, it maintains high performance but limited functions. The control mode can be divided into position control mode and speed control mode, analog input speed control mode and torque. control mode, etc.
MR-ES series: The encoder used with the servo motor adopts an incremental position encoder with a resolution of 131072 pulses/rev.
