The WATTSAVER® line of premium efficiency motors is now inverter capable. LEESON's unique IRIS™ voltage-spike-resistant insulation system is standard at no extra cost. WATTSAVER® motors carry a three-year warranty in general purpose and inverter fed applications. These motors meet or exceed most utility rebate programs and the EPACT federally mandated efficiency levels. The efficiency ratings have been independently verified to IEEE 112B test standards. Cast iron 170 series motors can be field modified for forced ventilation service to extend the inverter-fed operating range and an encoder package is stocked for closed-loop vector inverter systems.

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, non-hygroscopic, high temperature varnish are just a few features contributing to extra protection. All this plus second generation spike-resistant magnet wire. The IRIS™ total insulation system is standard at no extra cost in all LEESON stock NEMA three-phase motors, 1 HP and larger.

Used for extended low speed operation of inverter-fed motors, these kits can be field-installed on 150 and 170 Series Cast Iron Motors to provide constant velocity cooling. The 115 volt single phase, fan-drive motor is totally enclosed. The blower is mounted after removing the standard fan and fan cover. No shaft or other modifications to the motor are required.
