Toshiba “VR” series motors are built for the extreme operational requirements of today’s variable speed applications. These motors are designed for the most demanding applications requiring not only vector-operation capability, but survival in the severe environments associated with these applications as well. Toshiba “VR” series motors

are specically designed for inverter operation and are not intended for

conventional “across-the-line” operation.
