AC Inverter Motor Drive is the comprehensive flux vector control AC inverter. AC Inverter Motor Drive can be used in elevator, lift application. There are four control patterns: Standard V/F control, V/F control with PG feedback, Sensorless flux vector control and vector control with PG feedback. EI-Super provides the servo-like precision machinery to multiple types of motor drives. The capacity of AC Inverter Motor Drive is up to 900kW. Large power can be custom-designed in the cabinet protection.
Smooth operation, precise control and powerful functionality.
AC Inverter Motor Drive is a general-purpose inverter with flux vector control. It directly controls the current or torque in an AC induction motor. AC Inverter Motor Drive is suitable for a wide variety of applications.
AC Inverter Motor Drive provides smooth start-up at low speeds (1% of rated speed) and precise operation. Its auto-tuning function enables high performance tuning of all induction motors
AC inverter motor drive combines four control methods: open loop vector, flux vector, V/F control with PG feedback, V/F control
From precision machinery to multiple motor drives, El Super N proves to be the ultimate drive for all applications. Features

Any type of machine starts smoothly at slow speeds.
EI-Super N features full-scale flux vector current control that directly controls motor torque based on present control theory utilising a magnetic flux observer and neuro-control.
It features full torque control even at zero speed when PG option is added.
Precise control over a wide speed range.
EI-Super N features highly precise operation throughout the motor’s entire speed range, even under fluctuating load conditions.
Simply by selecting the parameters, EI-Super N can be applied to a wide range of applications from servo-like precision machinery to multiple motor drives.
Note: at low speed, high torque and continuous operation, a forced cooling special motor must be used
