Elevator inverter starting current

        When the motor starts running, the elevator inverter output current

        ------ elevator inverter drive when starting torque and maximum torque is less than the direct labor-power-driven ------

        Electric power supply in the frequency and acceleration when starting a big impact, and when using the elevator inverter power supply, these shocks will be weaker. Direct starting frequency will produce a large starting current. When using the elevator inverter, the elevator inverter output voltage and frequency is gradually applied to the motor, so the motor starting current and the impact to be smaller.

        Typically, the torque generated by the motor to decrease with increasing frequency (speed reduction) decreases. Reduce the actual data in the elevator parts - elevator inverter manual will give some explanation.

        By using flux vector control elevator inverter, will improve low-speed torque motor deficiency, even in the low speed range the motor can also be output sufficient torque.
