Inverter-Duty Motor Speed Ranges

General information is given because each application is unique with its own unique set of application characteristics. Successful motor/drive applications require proper setup and installation (in accordance with all applicable electrical codes and regulations) by personnel familiar with the installation, setup, and operation of adjustable speed drives. Proper adjustment of the adjustable speed drive, in accordance with the Installation and Operation manual that comes with it, must be performed to ensure that the motor/drive setup is complete and appropriate for the application. Failure to perform proper setup can lead to substandard performance and/or failure of system components. ..For constant Horsepower operation, the maximum speed for 2 pole (3600 RPM) motors is 75Hz, not 90Hz. Contact LEESON for application analysis if 90Hz is required.
