Embodiment Construction
[0026] The electromagnetic torque formula of permanent magnet assisted synchronous reluctance motor is as follows:
[0027] T e =p(L d -L q ) i d i q +pψ PM i q
[0028] Among them, p is the number of pole pairs of the motor, Ld is the direct axis of the motor, Lq is the quadrature axis inductance, id and iq are the components of the stator current space vector on the quadrature axis, ψPM is the flux linkage generated by the permanent magnet; the traditional permanent magnet assisted synchronous reluctance Motor Ld
[0029] see in conjunction Figure 1 to Figure 5 As shown, according to the embodiment of the present application, the motor rotor includes a rotor core 1 and a plurality...
