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.
- Features
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
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
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
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
Applications- Booster Oil Pumping Station
- Punch Press
- Tram Line in Mining Operation
- Surface Winder
- Application requirements; V/Hz (2%), sensorless vector (0.1%), or flux vector control (0.01% with motor-mounted encoder and drive-mounted PG-X2 card required).
