Abstract

The invention relates to a multifunctional electric controller of a clutch motor. A power supply of a motor is electrically connected with a single chip, a temperature sensor is arranged on a motor winding, and a clutch of the motor is connected with a Hall sensor. The electric signal output by the temperature sensor and the Hall sensor is processed by the single chip to output a power supply work command to drive the motor to work in different time intervals which comprise: A, a starting time interval in which a secondary winding of the motor is electrified, then a main winding supplies power under a single chip command when an input voltage wave shape is in a positive half cycle state, and a soft start is realized; B, a maintenance or energy storage time interval in which the main winding of the motor supplies power periodically and adjusts frequency at interval under the single chip command; C, a preparation and running interval in which the action of the clutch of the motor is sensed by the Hall sensor, and the electric signal is input to the single chip which outputs a full speed working command, so that the motor rapidly reaches a rated speed; and D, an operation interval in which the motor is in a full load work state at the rated voltage. The multifunctional electric controller has the characteristics of: 1, reducing the electric energy consumption by 25-55% for the clutch motor; 2, protecting the temperature of the motor; 3, delay tripping, performing non-load tripping and shutdown once exceeding the set time; and 4, cutting electricity for the grid and tripping.

Clutch motor is because manufacturing technology is simple, adaptability good, cost is low, is widely used in the 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: start----energy storage (no-load)----run (load), efficiency during operation is generally 10-70%.Its period distributes as shown in Figure 1: z----rotating speed Z1-runs (load) rotating speed Z2---maximum (top) speed S---time S1---section S1S2---start-up time energy storage time section operational efficiency and runs (load) time period S2S3---section running time operational efficiency at 10-70% at 30-90% S2S3---; Thus be necessary to be improved on this basis.

Summary of the invention

The object of the invention is to provide a kind of Multifunctional electric controller of clutch motor on the basis of existing technology.

Technical scheme of the present invention is achieved in that

A kind of Multifunctional electric controller of clutch motor is provided, it is characterized in that: motor power is electrically connected with single-chip microcomputer, motor winding is arranged a temperature sensor, the clutch of motor connects a Hall element, the signal of telecommunication that described temperature sensor and Hall element export, after single-chip microcomputer process, the instruction of output motor power work, thus drive motors runs on Different periods.

Multifunctional electric controller of clutch motor as above, is characterized in that: the described motor operation period is subdivided into: start/maintain (energy storage)/prepare to run/four periods of operation:

A. the period is started: motor auxiliary winding is energized, and then main winding zero passage power transmission under MCU Instruction, realizes soft start;

B. maintain or the energy storage period: motor main winding is powered to be interrupted mode of frequency regulation under MCU Instruction;

C. prepare to run the period: the action being sensed electric motor clutch by Hall element, and the signal of telecommunication is inputted single-chip microcomputer, single-chip microcomputer exports full speed operation instruction, makes motor reach rated speed rapidly;

D. the period is run: machine operation is in rated voltage full-load operation state.

Multifunctional electric controller of clutch motor as above, it is characterized in that: described temperature sensor is arranged on after on winding coil, when coil temperature is higher than the temperature value set, temperature sensor exports a signal of telecommunication to single-chip microcomputer, after single-chip microcomputer process, trip command is sent, relay tripping operation power-off to the relay controlling motor power.

Multifunctional electric controller of clutch motor as above, it is characterized in that: after electric motor starting, single-chip microcomputer does not receive in the time of setting the clutch operating and the signal of telecommunication that produces that Hall element detects, and sends trip command, relay tripping operation power-off to the relay controlling motor power.

Multifunctional electric controller of clutch motor as above, is characterized in that: after electric motor starting, and namely single-chip microcomputer starts to monitor power supply signal, and when monitoring grid cut-off, single-chip microcomputer sends trip command to the relay controlling motor power, relay tripping operation power-off.

The present invention after arranging above possesses following characteristics:

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

2, temperature protection is carried out to motor, exceed the temperature trip of setting.
