EQP Global® 661 – Medium Duty Industrial Motors
The Toshiba EQP Global® 661 motor is purpose-built for air-to-air heat exchanger systems operating in petrochemical and chemical processing environments. Designed for both constant-speed and inverter-duty applications, this Totally Enclosed Fan Cooled (TEFC) motor meets API 661 specifications and provides a 50,000-hour bearing life for belted operation. It is built to meet or exceed IEEE® Std. 841-2021 performance requirements and features an IP56 enclosure with a severe-duty, corrosion-resistant epoxy coating, delivering dependable performance even in harsh, high-humidity conditions up to 100% moisture exposure.
Key Features & Benefits
- Solid cast-iron design: Frame, end brackets, and junction box constructed for durability.
- Good efficiency performance: Engineered to meet NEMA Premium® or near-premium levels in many ratings.
- TEFC enclosure: Protected from dust, debris, and moderate moisture.
- VFD/ASD compatibility: Insulation and winding design support adjustable-speed operation.
- Balanced operation: Low vibration and sound levels to reduce wear on mechanical systems.
- Bearings & service life: Designed for long lifespan with proper lubrication and maintenance.
Ratings & Options
- Horsepower: Typically from 7.5 HP up through 75 HP (varies by frame)
- Speeds (60 Hz): 3600 / 1800 / 1200 RPM
- Voltages (60 Hz): 230/460 V dual, 460 V (application dependent)
- Frames: Common NEMA T-frame sizes (e.g. 213 – 365T)
- Mounting: Footed configurations with various mounting options
- Enclosure: TEFC (Totally Enclosed Fan Cooled)
