The SERVICE FIRST Motor, model MOT10512, is a dependable choice for HVAC systems, specifically designed for Trane and American Standard units. This motor offers a horsepower rating of 3/4 HP and operates at speeds of 1100 RPM on a 60 Hz frequency or 900 RPM on a 50 Hz frequency. It functions efficiently with a dual voltage setup, handling 460V at 60 Hz and 380-415V at 50 Hz, with a full load current of 2.8 amps, and is designed for single-phase applications. Constructed with a NEMA 48 frame size and a PSC (Permanent Split Capacitor) motor type, it requires a separate 10 MFD / 440V capacitor for optimal performance. The motor features a Totally Enclosed Air Over (TEAO) enclosure, ensuring protection against moisture and debris, making it suited for outdoor environments. With heavy-duty ball bearings and a CCWLE (Counter-Clockwise Lead End) rotation, it is engineered for reliability and smooth operation. Additional features include a 1/2" diameter shaft with a 2.5" length, and it's primarily suited for vertical shaft down mounting orientations. This motor is a suitable replacement for OEM components in commercial HVAC settings, offering durability and efficiency for continuous use.
