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...

Abstract

The invention provides a comprehensive protector for an intelligent motor, which comprises a monolithic processor, a power supply and an LED display. The comprehensive protector is characterized in that the monolithic processor is connected with the LED display, and the monolithic processor performs data processing by adopting an MSP430F149. The invention has the characteristics of rapid, accurate and reliable action.

Description

1. Technical field: [0001] The invention belongs to a motor transmission protection system. 2. Background technology: [0002] Similar products in the existing market are only protected from the current aspect, and cannot identify the motor no-load problem that occurs when the mechanical structure fails. Continued operation in this case often causes secondary damage to the driven machinery. 3. Contents of the invention: [0003] The object of the present invention is to provide an intelligent motor comprehensive protector to avoid the above disadvantages. [0004] The technical scheme of the present invention is: the intelligent motor comprehensive protector is composed of a single-chip microcomputer, a power supply and an LED display, and is characterized in that the single-chip microcomputer is connected with the LED display. [0005] The MSP430F149 is used for data processing. [0006] The beneficial effect of the invention is that the motor protector has the characte...
