IRIS Insulation System

DUE TO LEESON’S PATENTED IRIS INSULATION SYSTEM, ALL LEESON 3 PHASE MOTORS 1 HP AND LARGER, EXCEPT FOR ULTIMATE E MOTORS, ARE RATED FOR INVERTER DUTY.

LEESON’S INVERTER-RATED INSULATION SYSTEM (IRIS™), PROVIDES SUPERIOR PROTECTION AGAINST VOLTAGE SPIKES INDUCED BY VARIABLE FREQUENCY DRIVES.

This total insulation system protects better than spike-resistant magnet wire alone. Specially formed phase insulation, cushioned and sleeved connections (from the leads all the way into the turns), and deep-penetrating, nonhygroscopic, high temperature varnish are just a few features contributing to extra protection. All this plus second generation spike-resistant magnet wire. Suitable for use with an inverter at speed ranges of 10:1 for variable torque and 10:1 for constant torque. With blower kit, and proper inverter setup, suitable for use up to 20:1 variable torque and 20:1 constant torque. EPACT motors have efficiencies that meet or exceed EPACT standards.
