Abstract
The utility model provides a motor with a voltage transformation function, comprising a working winding I2 and a voltage transformation winding I3. The I2 is used as a primary coil of a transformer, and the I3 is used as a secondary coil of the transformer; when direct current voltage needs outputting, the voltage transformation winding I3 is connected with a rectifying filter circuit. The utility model is suitable for the situation that a motor works and a small power low voltage power supply or a discontinuous instant large power supply is needed.
Description
The utility model relates to a kind of motor, particularly relates to a kind of motor of double transformation function.
Existing motor is the centre tap output low-voltage AC that utilizes the work winding, its weak point is that this low-voltage AC does not have and mains isolation, poor safety performance, and can not filtering export the very little direct voltage of ripple coefficient, because filter capacitor can change the startup capacitance size of motor, influence the phase difference between work winding and startup winding, thereby make the motor cisco unity malfunction.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of and has both reached as small-power or interruption moment high power AC or DC power supply, plays the motor of the double transformation function of transformer isolation effect simultaneously again.
The hold concurrently motor of transformation function of the utility model is to realize like this, its circuit comprises work winding I2 and transformation winding I3, utilize work winding I2 to make transformer, when motor is threephase motor, only utilize one of them work winding I2 to make primary coil level coil, utilize transformation winding I3 to make the transformer secondary output coil.As want output dc voltage, then transformation winding I3 is connected with current rectifying and wave filtering circuit.Current rectifying and wave filtering circuit is by bridge rectifier B1, and resistance R 1 and filter capacitor E1 constitute, and its annexation is, I3 two termination B1 inputs, and R1 and E1 are connected in parallel between B1 output CD.When motor is unidirectional motor, be connected to the I2 two ends after startup winding I1 and the capacitor C series connection.
The hold concurrently motor course of work of transformation function of the utility model is that motor is connected civil power, motor operation, because of among its work winding I2 alternating current being arranged, so induce alternating electromotive force among the transformation winding I3, at I3 two ends output AC voltage, its magnitude of voltage is by the turn ratio decision of I2 and I3.As through the exportable direct voltage of current rectifying and wave filtering circuit.
The hold concurrently advantage of motor of transformation function of the utility model is not influence electric motor normal working, increase fail safe, had the transformer function simultaneously, can dwindle the complete machine space, be suitable for having motor work, and need the field boundary of small-power low-tension supply or discontinuous large power supply to close.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
