Example Embodiment
[0009] Referring to the attached drawings, the intelligent motor comprehensive protector is composed of a single-chip microcomputer 1, a power supply 3, and an LED display 2. Its characteristic is that the single-chip microcomputer 1 and the LED display 2 are connected.
[0010] The one-chip computer 1 adopts MSP430F149 for data processing.
[0011] Real-time acquisition of the three-phase voltage and current parameters of the motor, relying on the high-speed data processing of the internal MSP430F149 single-chip microcomputer, quickly and comprehensively calculate and judge the running state of the motor. When a fault occurs, there is a corresponding indicator light, and a faulty coil acts. In addition to the traditional voltage and current protection of the motor, it has an outstanding protective effect especially when the mechanical structure is broken. Mainly can be realized: inverse time limit overload protection, phase failure protection, phase unbalance protection, gambling...
