On traverse applications (bridge/trolley) conical-rotor motors do not present any issues. Our VFDs work with these types of motors just like a cylindrical motor – except you may not be able to use the VFD to control the motor at a very low creep speed. With a conical motor, you also won’t need any additional brake control contactors or circuitry either. So in these cases, you can size the VFD using the motor specifications, just like normal.
However, if you are working with a conical brake motor on a hoist/lifting application, there will be some additional factors and a “standard VFD” solution is not recommended. Contact PE® for further information in this case.
