SERVO SYSTEM OF PERMANENT MAGNETIC SYNCHRONOUS MOTORS SEPARATED POWER SUPPLIES

摘要

A servo system of PMSM(Permanent Magnetic Synchronous Motor) is provided to facilitate maintenance and repair of a servo drive by performing an overall variable monitoring of the servo drive through a CAN(Control Area Network) communication. A servo system(100) of PMSM includes a plurality of servo drives and a single power source module(140). The servo drive controls a PMSM(200) according to a signal of a high rank controller or a motion board. The power source module supplies a power source supplied from an external power supply part to the servo drive. The servo drive includes a signal input/output part, a sensing part, an A/D converter, and a controller. The signal input/output part performs a signal delivery of the high rank controller or the motion board. The sensing part senses a current and a voltage for controlling the PMSM. The A/D converter converts an analog signal inputted form the signal input/output part and the sensing part into a digital signal. The controller stores data required to a control of the PMSM, and outputs a control signal for controlling the PMSM.
