Application Notes
Restricted use
DO NOT APPLY THE FOLLOWING MOTORS ON VARIABLE FREQUENCY DRIVES:
Single Phase motors, Motors with inherent overload protection, Multi-Speed motors, Motors with 1.0 Service Factor on sine wave power.
Fire Pump motors should not be used with variable frequency power supplies, due to the critical nature of these applications.
Hazardous Locations Consult with LEESON Electric when applying motors and drives into Hazardous Locations, either Division/Zone 1 or Division/Zone 2 areas.
UL and CSA policies prohibit the installation of bearing protection devices, such as shaft grounding brushes, rings or insulated bearings on
motors in Hazardous Locations.
Guidelines for Application of General Purpose, Three Phase, Single Speed Motors on Variable Frequency Drives Meets NEMA
MG1-2006 Part 30 and Part 31 Section 4.4.2 Unless stated otherwise, motor nameplates do NOT include listed speed range.
Maximum Cable Lengths from the Motor to Drive
* Higher carrier frequencies require shorter cable length to obtain normal (50Khrs) insulation life.
