Fig. 1 is circuit principle structure block diagram of the present utility model.
Embodiment
As shown in Figure 1, the Controller for PM DC Brushless Motor used for electric vehicle of two times of expansion speeds described in the utility model, comprise microcontroller, be connected to sampled voltage signal, sampled current signals, the speed-regulating signal of described microcontroller signal input part, and be connected to the CAN signal of micro-controller communications interface; Microcontroller detection signal input is connected with the position sensor signal output for detecting described permanent-magnet brushless DC electric machine angle of rotor, microcontroller output control terminal is through pulse width modulation module and IGBT(insulated gate bipolar transistor) power driver module input is connected, described IGBT power driver module output is connected with inverter control input, and described inverter output end is connected with the power input of permanent-magnet brushless DC electric machine.
During utility model works, after the signal that position transducer detects by microcontroller carries out logical conversion, the each power switch pipe of inverter is outputted to through pulse width modulation module and IGBT power driver module, thus each winding of permanent-magnet brushless DC electric machine is worked in sequence, and in air gap, produce the rotating magnetic field of jump, like this, rotor field is subject to the rotating magnetic field effect in air gap, just rotates along fixing direction continuously.
When rotor turns over 60 degree of electrical degrees, just once commutate between inverter switching device pipe, stator magnet state just changes once; Each commutation, have a winding switching to the positive pole controlling power supply, the second winding switching is to the negative pole controlling power supply, and the tertiary winding is in power failure state.Torque is that the interaction between magnetic field and permanent magnet produced by stator coil produces, therefore ideally, when torque peak appears at two magnetic field orthotropics, and the most weak when two magnetic fields are parallel.
