TWO-SPEED, TWO-WINDING VARIABLE TORQUE FOR BELT DRIVEN OR SHAFT MOUNTED FAN APPLICATIONS

Variable torque, two-speed motors are suited for belted or fan on shaft applications. They are self ventilated, and may be mounted within or outside of the driven fan's air stream.

Resilient mounted for quiet operation, and lubricated with high temperature Shell Dolium R lubricant.

3/4 HP and larger single phase are capacitor start motors; smaller single phase are split phase start.

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.
