A motor power supply is electrically connected with a singlechip; a motor winding is provided with a temperature sensor; a clutch of the motor is connected with a Hall sensor; and electric signals output by the temperature sensor and the Hall sensor are processed by the singlechip to output a motor power supply work instruction so as to drive the motor to run in different time periods. The set multifunctional electric controller of the clutch motor is characterized in that the electric energy consumption of the clutch motor is reduced by 25% to 55%, the performance of original equipment is not affected simultaneously, and the production efficiency is not reduced; temperature protection is carried out on the motor and trip is carried out when the temperature excesses a set value; the strip is delayed and no load strip and switch off are carried out when the time excesses a set value; and a power grid is switched off and stripped.

Description

The multi-functional automatically controlled device of clutch motor

Technical field

The utility model relates to automatic control motor operation field, specifically a kind of electric control gear of clutch motor.

Background technology

Clutch motor is because manufacturing technology is simple, adaptability good, cost is low, is widely used in fields such as clothing, shoemaking, chemical industry.This small-sized AC asynchronous motor torque is low, dynamic characteristics is soft, and its mode of operation is:----energy storage (no-load)----operation (load), the efficient during operation generally is 10-70% in startup.Its period distributes as shown in Figure 1: z----rotating speed Z1-operation (load) rotating speed Z2---maximum (top) speed S---time S1---section start-up time S1S2---energy storage time section operational efficiency is moved (load) time period S2S3---section running time operational efficiency at 10-70% at 30-90%S2S3---; Thereby be necessary to be improved on this basis.

The utility model content

The purpose of this utility model is to provide a kind of clutch motor multi-functional automatically controlled device on the basis of existing technology.

The technical solution of the utility model is achieved in that

Provide a kind of clutch motor multi-functional automatically controlled device, it is characterized in that: motor power is electrically connected with single-chip microcomputer, one temperature sensor is set on the motor windings, the clutch of motor connects a Hall element, the signal of telecommunication of described temperature sensor and Hall element output, after single-chip microcomputer is handled, the instruction of output motor power work, thus drive motors runs on the different periods.

The multi-functional automatically controlled device of aforesaid clutch motor is characterized in that: the described motor operation period is subdivided into: start/keep (energy storage)/prepare four periods of operation/operation:

A. start the period: the energising of motor auxiliary winding, main winding zero passage under the single-chip microcomputer instruction is sent electricity then, realizes soft start;

B. keep or the energy storage period: the motor main winding is powered to be interrupted mode of frequency regulation under the single-chip microcomputer instruction;

C. prepare the operation period: the action of sensing electric motor clutch by Hall element, and signal of telecommunication input single-chip microcomputer, single-chip microcomputer output full speed operation instruction makes motor reach rated speed rapidly;

D. move the period: machine operation is at rated voltage full-load operation state.

The multi-functional automatically controlled device of aforesaid clutch motor, it is characterized in that: after described temperature sensor is arranged on the winding coil, when coil temperature is higher than the temperature value of setting, temperature sensor is exported a signal of telecommunication and is given single-chip microcomputer, after single-chip microcomputer is handled, relay to the control motor power sends trip command, relay tripping operation outage.

The multi-functional automatically controlled device of aforesaid clutch motor, it is characterized in that: behind the electric motor starting, single-chip microcomputer does not receive the clutch operating that Hall element detects and the signal of telecommunication that produces in the time of setting, and sends trip command, relay tripping operation outage to the relay of control motor power.

The multi-functional automatically controlled device of aforesaid clutch motor is characterized in that: behind the electric motor starting, single-chip microcomputer promptly begins to monitor power supply signal, and when monitoring grid cut-off, single-chip microcomputer sends trip command to the relay of control motor power, relay tripping operation outage.

Through more than the utility model after being provided with possess following characteristics:

1, reduces clutch motor electric energy consumption 25-55%, do not influence the original equipment performance simultaneously, do not reduce production efficiency.

2, motor is carried out temperature protection, surpass the temperature tripping operation of setting.

3, delay tripping surpasses non-loaded tripping operation of the time of setting and closes.

4, grid cut-off tripping operation.
