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:

32bit DSP microprocessor configuration 

‧ magnetic field oriented flux vector control 

‧ auto-tune ability 

‧ available for speed-type servo controller while PG feedback added 

‧ RS-232/RS-485 serial communication port 

‧ RS232/TCP-IP interface card 

‧ capacities from 1HP – 400 HP 

‧ optional DC reactor available (for reducing harmonic interference from the power supply) 

‧ multi-language large screen LCD displays the drive status in six languages and a parameter copy mode function. 

‧ English, ‧ Chinese, ‧ Russian, ‧ German, ‧ French, ‧ Spanish

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
