Gozuk - Model GK3000 Series -General Purpose AC Drives
GK3000 series AC drives are manufactured based on sensorless vector control, current control, V/F control and vector space control techniques to change the AC asynchronous motor running speed by controlling the output frequency. GK3000 AC drives adopt world-class space voltage SPWM control technology, built-in current control loop to achieve high-precision closed-loop control mode for high accuracy requirements. According to thousands of China local customers' feedback, Gozuk variable frequency drives are suitable for paper industry, constant water pressure supply, metallurgy and other high control precise requirement industries.
Power range:
- 1 phase 0.2kW - 3.7kW
- 3 phase 0.75kW - 400kW
Definition: AC drive is a power control conversion device to change commercial power supply (50Hz or 60Hz) to another frequency power by inner power semiconductor on/off behaviors, to control AC motors in variable speed operations. Variable frequency control is changing the frequency supply to the motor stator windings to achieve variable speed control purpose.
AC Drive also called frequency inverter, variable frequency drive (VFD) and AC motor speed drive etc. it allows the electric motor smooth start up, control startup current growing from zero to motor rated current, reduce impact to the power grid and avoid the motor being burned out, also provide protect in motor running process. Besides these functions, the main function of AC drive is adjusting the motor running speed according to actual operation conditions, to achieve energy saving effect.
