AC Drives EI Super N

EI Super N

220V Class (3-Phase Input) 0.75kW~75kW
440V Class (3-Phase Input) 0.75kW~900kW

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, EI-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 low 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.

Four controls in one device; the ultimate device for all applications

Four control methods are included:

  • Standard V/F control
  • V/F control with PG feedback
  • Sensorless flux vector control
  • Flux vector current control with PG feedback

Simply select the parameters, EI-Super N can be applied to a wide range of applications from servo-like precision machinery to multiple motor drives.

Factory presets default to sensorless vector control type, but it can be configured to the V/F control mode for applications requiring multiple motors on one device, or set to flux vector current control mode (with PG) for hughly precise vector operation. (PG-B interface card is optional)

Note: at low speed, high torque and continuous operation, a forced cooling special motor must be used
