UNI-DRIVE stainless steel motors are engineered to meet the most demanding sanitation, corrosion-resistance, and washdown requirements in food, beverage, pharmaceutical, and processing industries. Constructed with 300-series stainless steel housing and TEFC enclosure, these motors deliver superior anti-corrosion protection, excellent heat dissipation, and long-lasting performance in harsh washdown and high-humidity environments. Designed for continuous washdown duty with a 1.15 service factor, sealed bearings, interior anti-corrosion coating, and robust squirrel-cage rotor, the NS series is ideal for applications requiring both hygiene and durability. With flexible configurations including C-face or footed mounting, inverter compatibility, IP55 protection and thermistor protection, UNI-DRIVE stainless steel motors combine energy efficiency, reliable operation and simplified maintenance for critical industrial processes. wannanmotor.net
