Abstract: The application provides a motor control method for driving a motor. The motor control method includes: at a normal status, when the motor outputs power, determining whether an output current of the motor reaches a maximum current limit; when the output current of the motor reaches the maximum current limit, controlling the motor to enter a boosting status to raise a maximum instantaneous output power of the motor; and when the motor has reached a maximum time limit within a boosting period at the boosting status, or when the output current of the motor drops from the maximum current limit, controlling the motor to return to the normal status from the boosting status.

Abstract: A boost circuit and method is described for supplying a boost voltage to a rotor of the electric machine, just as the electric machine is pulsed on, the boost voltage aids the rotor in quickly overcoming its start-up inductance, rapidly turn on the rotor. As a result, much faster transition times are realized each time the electric machine transitions from the off state to the on state at the start of a pulse. By reducing the transition time, the overall efficiency of the electric machine is significantly improved.

Abstract: A voltage doubling circuit that increases input voltage to higher output voltage connected to a variable frequency drive. The voltage doubling circuit can include a power input that receives the input voltage from a power source and a first capacitor bank and a second capacitor bank connected with the power input. A current-limiting surge suppressor is positioned between the power input and the first capacitor bank and the second capacitor bank. The current-limiting surge suppressor includes a first current-limiting path and a second bypass path. A drain, when operable, dissipates the charge of the first capacitor bank and the second capacitor bank. A variable frequency drive (VFD) is operable in response to the higher voltage output from the first capacitor bank and the second capacitor bank.
