Embodiment 2

[0029] Such as figure 2 As shown, the DSP control system generates a pulse width modulation PWM signal by logically changing the detection of the rotor position sensor signals of the upper and lower motors. The generated control signal is added to the three-phase bridge inverter circuit of the upper motor and the lower motor through the power drive chip. In the three-phase bridge inverter circuit, each three-phase bridge inverter circuit includes six switching tubes. The motor needs to go through six commutations per revolution. Each commutation has two switching tubes conductive, but each The upper and lower tubes cannot be turned on at the same time. The different order of the switching tubes are turned on to control the phase windings of the motor to work in a certain order, so a jumping rotating magnetic field is generated in the air gap of the motor, and the motor can rotate.

Description

Technical field [0001] The invention relates to the field of electrical control, in particular to an integrated magnetic suspension energy storage flywheel dual motor control system. Background technique [0002] Magnetic levitation energy storage flywheel is a new generation of physical energy storage device. It has the advantages of high power, high energy storage density, environmental protection, strong anti-interference and fast response, etc. It has gradually been applied internationally, and It will definitely become the preferred energy storage method for my country's new generation of large-scale energy storage devices. [0003] Since the magnetic levitation energy storage flywheel needs to supply power to the control system through its own stored energy to realize the levitation control of the flywheel and the charge / discharge control in the case of ultra-high speed, therefore, the accuracy, reliability and stability of the overall motor control device Higher requirements...
