The WEG CFW-11 Series of Variable Speed Drives incorporate the world's most advanced technology in drives for three-phase AC induction motors.
The Vectrue Technology™ represents a significant advancement, allowing this new generation of WEG inverters to combine V/F, Sensorless Vector and Closed Loop Vector (with encoder) control techniques, all in one product.
WEG's patented Optimal Flux ® technology can be utilised when combining a WEG W22 motor with a WEG CFW 11 VSD. This is possible because WEG have pre-loaded the design characteristics into their VSD. The Optimal Flux ® control algorithm increases motor flux at low speeds, thereby allowing the same torque to be developed with lower current. The results are optimal motor flux at low speeds to produce full torque while minimising motor losses.
