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 specifically designed for inverter operation and are not intended for 

conventional “across-the-line” operation.
