| titleOfInvention | Method for controlling direct current brushless motor and device |
| abstract | The invention provides a kind of method for controlling direct current brushless motor and device, this control method comprises actual speed and the rotor position angle of the calculated signals rotor exported according to position transducer, the numerical value of voltage modulated than factor is calculated according to actual speed and the rotating speed of setting, and, according to the numerical value of voltage modulated than factor, position angle position and dead area compensation value calculate the magnitude of voltage that the three-phase bus to DC brushless motor loads, the magnitude of voltage that at least two-phase bus loads wherein is that voltage modulated adds dead area compensation value than the numerical value of factor and the product of position angle trigonometric function value.This control device utilizes above-mentioned control method to calculate the magnitude of voltage loaded to three-phase bus.The present invention can avoid Dead Time to be greater than the contiguous voltage modulated ratio of commutation point, thus cause machine winding current to end in advance, cause torque pulsation, the problems such as commutation noise, field effect transistor can also be avoided to carry out switch for a long time, extend the useful life of field effect transistor and motor. |
