PURPOSE: To optimize a motor performance functionally with regard to current speed, a load, maximum acceleration, motor vibration, and the like, by monitoring a control unit through a monitor unit. CONSTITUTION: A three-phase inverter 1 comprises a six valves being controlled through inputs A+ -C- connected with the corresponding outputs of a control unit 2. The control unit 2 has inputs r, s, t being fed with a rotor position signal from a counter electromotive force detector 5 detecting zero crossing on a feeder line. The inverter 1 is fed with power from a battery 11 through a control unit 10 operating in conjunction with pulse modulation from the control unit 2. Function of the control unit 2 is monitored by a monitor unit 4. According to the system, motor performance can be optimized regard to current speed, the load, maximum acceleration, motor vibration, and the like. |
