| Popis: | The asymmetric dual-three phase BLDC motor has two sets of stator windings, in which the back EMF coefficients are different. This paper takes advantage of the asymmetric dual-three phase BLDC motor's structural features and proposes a new method for the accelerated problem of the BLDC motor operating in the high speed and the constant electromagnetic power. The dual phase windings of the BLDC motor are integrated into the circuit in the starting stage. When the motor's back EMF value is equal to the terminal voltage value, switch off a set of RST three phase windings whose back EMF coefficient is bigger and make the other set of stator winding UVW with smaller back EMF coefficient continue to operate under the rated power. As the motor rotor speed continues to increase, the electromagnetic torque remains unchanged. By using the peak current control strategy, we can deduce that the phase current of the UVW three-phase winding is twice the RST three-phase winding when the asymmetric dual-three phase BLDC motor operates at high speed and constant power. |
