Asynchronous motors for inverter vector control VT series

Generality

The VT series vectorial motors have been designed to offer the highest performance and the maximum flexibility when supplied by inverter. The high ratio between power and dimensions accompanied by an excellent dynamic performance make this type of motor suitable for many different types of applications. They are particularly used for industrial applications where are necessary high speed and performance.
