The micro-control device of the electric-storable permanent-magnet synchronous motor can also regulate and make the electric-storable permanent-magnet synchronous motor change the rotation speed. According to the "storable permanent magnet synchronous motor and its circuit device" as described in claim 1, the storageable permanent magnet synchronous motor can control the AC-DC rectifier to be open-circuited as a cut-off by the microprocessor of the micro-control device. Turn on to stop the single-phase AC power source outside the electric storage permanent magnet synchronous motor from supplying power to the flexible motor battery of the electric storage device via the AC-DC rectifier (motor battery stops AC power storage), and control the DC-DC conversion The device is an open circuit to cut off the conduction, so that the DC power source outside the electric storage permanent magnet synchronous motor stops supplying power to the flexible motor battery of the electric storage device through the DC-DC converter (the motor battery stops the DC power storage), and Using only the flexible motor battery to power the first coil group stator after commutation via the first phase modulation converter, and power to the second coil group stator after commutation via the second phase modulation converter, Power is supplied to the third coil group stator after being commutated through the third phase modulation converter, and the first coil group stator, the second coil group stator, the third coil group stator, and the N magnet rotor and S magnet turn The electromagnetic induction action between them starts and drives the N magnet rotor and S magnet rotor to rotate to drive the load (the motor and battery directly supply the permanent magnet synchronous motor). When the N magnet rotor and the S magnet rotor rotate and work, the external single phase The AC or DC power supply can stop supplying power to the flexible motor battery (the motor battery stops storing power) without affecting the normal operation of the load; therefore, the micro-control device of the electric storage permanent magnet synchronous motor can be operated to control the The single-phase AC or DC power supply outside the electric storage permanent magnet synchronous motor can stop supplying power to the electric storage permanent magnet synchronous motor (the permanent magnet synchronous motor does not need an external power supply), and make the flexible type inside the electric storage permanent magnet synchronous motor flexible. The motor battery can directly supply power to the electric storage permanent magnet synchronous motor (the permanent magnet synchronous motor uses an internal battery).
