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.
