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 specically designed for inverter operation and are not intended for
conventional “across-the-line” operation.
