4The arrangement of position, wherein 4 A (4 B, 4 C) evenly distribute on circumference, on it around being connected into a phase winding mutually.Whole motor has A, B, C three phase windings, so this motor is a threephase motor.
2, circuit control principle
To motor phase winding energising, make contiguous rotor tooth and this electromagnetic torque of coinciding of stator tooth mutually with producing one.Order then can change the rotation of motor to each phase winding energising (as A-B-C-A......).Be close into to the winding energising at the stator and rotor utmost point, can realize the motor operation; Energising can realize running under braking when leaving mutually.Thus, if will accurately control the operation of motor, the rotating speed that then need detect motor rotor turns to and instantaneous position, the effect of Here it is transducer.
Fig. 4 has represented being connected of the power circuit in the controller and motor winding.Three-phase alternating-current supply is converted to DC power supply through diode rectifier circuit V.6 GBT power switch TA, TA ', TB, TB ', TC, TC ' and fly-wheel diode DA, DA ', DB, DB ', the half bridge inverter circuit that DC, DC ', composition three-phase can work independently.When two power switchs of arbitrary phase (TA, TA ') conducting, direct current is by terminal (A
1, A
2) by this motor windings.When two power switchs turn-offed, then winding was by fly-wheel diode (DA, DA ') afterflow and feedback energy.
The effect of control board is constantly to regulate its output signal according to the practical operation situation of peripheral operation control requirement and motor.
Power circuit in Fig. 4 controller.Three-phase alternating-current supply diode rectifier bridge V is converted to DC power supply.Six IGBT power switchs and fly-wheel diode are formed the three-phase half bridge inverter circuit, power to motor three phase windings respectively.When a phase power switch (as TA, TA ') conducting, through terminal (A
1, A
2) switch on to motor winding (A group).When power switch turn-offed, this winding to capacitor C afterflow and feedback energy, and made electric current rapidly to zero by afterflow two (DA, DA ').Here power switch is in series with the motor winding, the danger of having avoided bridge inverter main circuit little bridge arm unit shoot through easily to take place to go up as (frequency converter), so the functional reliability height, protective circuit also can be simplified.All power components are installed on the heating panel, compact conformation, good heat dissipation effect.
The effect of control circuit is the continuous adjusting output signal according to peripheral operation control requirement and motor practical operation situation, to change the energising moment of motor winding by drive circuit and power circuit, make it to reach the service requirement of regulation, as turn to, torque, rotating speed, electronic and braking etc., and be in optimum Working.Control circuit is made up of a single-chip microcomputer and numeral, analog circuit, working stability, anti-interference strong, response is fast.
