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.

Constant Torque Applications

Variable Torque Applications

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.

ENCODER KITS • 150 & 170 SERIES

These kits include the parts and encoder for field assembly of a slim-line, through-shaft encoder to LEESON standard TEFC 150 and 170 Series Cast Iron Motors. Designed to slip over the motor's fan end shaft.
Output is 1024 pulses per revolution, quadrature, 5 to 28 VDC line driver output. Short circuit protection is standard. Inputs are over voltage and reverse voltage protected. Electrical noise immunity exceeds international standards. Encoders are isolated from shaft currents using hard anodized sleeves and non metallic anti-rotation hardware. Designed for long life in industrial environments using an all metal, shock resistant code disk. The encoder is protected by the motor's fan cover after mounting.
