The output torque of brshless DC motor is directly proportional to its phase winding electric current, and the larger output torque of electric current is just larger.In the time starting mixer, often need larger moment, because controller cannot directly be measured brshless DC motor output torque, so carry out indirect detection brshless DC motor output torque by the mode that detects brshless DC motor electric current.When startup, set a starting current I to brshless DC motor, as 30A, make it have certain initial torque, the size of described starting current I is to determine on brshless DC motor characteristic and the comprehensive basis of analyzing of load characteristic.
With reference to figure 2, Fig. 2 is the method schematic diagram that brshless DC motor is provided under a kind of constant current of providing of the embodiment of the present invention.In the time starting brshless DC motor, control unit is crossed the current value of brshless DC motor by current detecting unit reading flow, judge whether to exceed setting electric current I, if exceed setting electric current I, control unit just reduces brshless DC motor electric current by pulse width modulation (Pulse Width Modulation, PWM); If do not exceed setting electric current I, control unit just increases brshless DC motor electric current by pulse width modulation (PWM), finally makes current of electric be stabilized in set point.
