Abstract: A permanent magnet motor including a stator, a rotor and a control circuit. The control circuit is the closed-loop control circuit, including a speed control device, a torque control device, a voltage vector control device, a space vector control device, and an inverter control device connected in sequence. A stator magnetic circuit includes a magnetic linkage correction circuit, the magnetic linkage correction circuit is composed by a single integrator and a low-pass filter connected in series; Small leakage, small magnetic chain harmonic of permanent magnet, small eddy current loss and iron loss of motor, good control accuracy, no shaking of motor rotor and a long service life can obtained.
