Description

The clutch Energy-saver for electric machine

Technical field: the utility model belongs to Energy-saver for electric machine, the clutch Energy-saver for electric machine that the especially a kind of tailor's of being used for high speed machine is used.

Background technology: existing high speed sewing machine, make the motor of limit machine etc., power consumption is big.For example, the car dress approximately needs 30 minutes, and the 16 minutes time of the actual clothing of getting on the bus, other 14 minutes is the time of high-speed electric expreess locomotive idle running.Power consumption is up to more than 40% like this.

Summary of the invention: the technical scheme that the utility model solves is such, comprise by rectification circuit, automatic control circuit, alignment circuit, constitute rectification circuit by transformer B, resistance R 4-R6, capacitor C 3, potentiometer W2, diode D6, D7 connection, constitute automatic control circuit by triode Q, diode D2-D5, resistance R 3 connections, constitute alignment circuit by bidirectional triode thyristor DQ, capacitor C 1, C2, resistance R 1, R2, voltage-stabiliser tube D1, potentiometer W1 connection.Element in the electrical schematic diagram is welded on the circuit board, is installed in the box body lead and is serially connected in 220 volts of power supplys of motor.

The utility model has the advantages that simple in structure, stable performance, easy to install, energy-conservation more than 40%, prolong motor useful life.Be applicable to tailor's machinery.

Description of drawings:

Fig. 1 is an integral installation configuration diagram of the present utility model.

Fig. 2 is an electrical schematic diagram of the present utility model.

Among Fig. 1, Fig. 2, energy-saving appliance (1), motor (2), transformer B, resistance R 1-R6, capacitor C 1-C3, diac D1, diode D2-D7, triode Q, controllable silicon DQ, potentiometer W1, W2.

Embodiment:

Most preferred embodiment of the present utility model is: with reference to shown in Figure 2, the former edge joint power supply of the transformer B of rectification circuit, secondary parallel resistance R6, R5, capacitor C 3, potentiometer W2, capacitor C 3 positive terminating diode D6 negative poles, the negative pole of C3 arrives the triode e utmost point after meeting R4, the b utmost point of the triode Q of automatic control circuit connects the positive pole of D6, diode D2, D3, D4, D5 is linked to be bridge rectifier, the ce utmost point of triode Q in parallel, output is coupled to alignment circuit by resistance R 3, the trigger electrode serial connection R2 of the bidirectional triode thyristor DQ of alignment circuit, connect R3 and potentiometer W1 behind the D1, R1, the trigger electrode of DQ connects behind the C1 to 1. connecing power supply behind the pin, diac D1 meets transformer B after meeting C2, the 2. pin of DQ meets transformer B, and the potentiometer W1 in the circuit adjusts the trigger electrode current potential of controllable silicon DQ, and potentiometer W2 adjusts the sensitivity of automatic control circuit.Element in the electrical schematic diagram is welded on the circuit board, is installed in the box body lead and is serially connected in 220 volts of power supplys of motor.

Operation principle is: when electric motor starting, coupling transformer B produces induced voltage, makes triode Q conducting, D2, D5 conducting cause the D1 current potential to raise conducting controllable silicon DQ, output HIGH voltage makes motor reach rated speed, and rotating speed just often, current of electric descends, and makes transformer B no-voltage, and triode Q ends, D2, D5 end, and the D1 current potential descends, and causes controllable silicon DQ lightly conducting, motor speed reduces, and reaches purpose of energy saving.
