Adopting advanced, mature high performance vector control technique, the exact decoupling control is realized to the motor, function of the motor is displayed sufficiently, and then, the elevator can offer more comfort operation feeling. Compared with tradition sine PWM (SPWM) method, advanced space vector PWM (SVPWM) has higher electric energy utilization ratio, especially in energy conservation.

The elevator intelligence logic control and high performance frequency converter speed regulation drive fuse organically for an integral whole. Resource shared and intensive highly, realizing the elevator integrated control really.
 Apply to gearless permanent magnet synchronous motor and induction motor.
 Rotating or static motor parameter self study, motor initial angle self study.
Supporting an accumulator to supply electricity emergency works while the power failure.
Fuzzy control no-load compensation starting, adopting the pulse coder can gain comfortable good starting feeling even if the elevator does not assemble weighing device..
