Marathon C1156 Motor
The Regal Rexnord Marathon C1156 Motor is a 3/4 HP, single-phase electric motor designed for compatible HVAC and industrial equipment applications. Rated for 115/208–230 VAC operation, this Marathon 3/4 HP electric motor delivers a nominal speed of 1725 RPM with listed current ratings of 13.3/6.5–6.6 amps. Its NEMA 56 frame provides standardized mounting dimensions for compatible equipment installations.
This 1725 RPM single-phase motor features an open drip-proof (ODP) enclosure, ball bearings, and a resilient base designed to help reduce vibration transmission to the mounting surface. The motor also features capacitor-start operation, automatic thermal protection, and a 1.25 service factor.
When replacing an existing Marathon C1156 replacement motor, technicians should verify horsepower, voltage, full-load amperage, shaft dimensions, mounting configuration, and rotation direction. The 56-frame ODP electric motor is intended for installations where the enclosure type and operating environment are appropriate. Confirm electrical connections and overload protection using the manufacturer's wiring diagram and motor nameplate before installation.
