SM PLUS SUB-MICRO INVERTERS
Premium efficiency WATTSAVER® motors are specifically designed for use with inverters and carry a three-year warranty.
All LEESON stock NEMA three phase motors (1HP and larger) are protected by the Inverter Rated Insulation System (IRIS™). The system provides superior motor 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 the extra protection. All this plus secon generation, spike-resistant magnet wire. The IRIS™ total insulation system is standard at no extra cost in all LEESON stock NEMA three-phase motors, 1HP and larger.
