Overview
The Baldor CM3541 is a three-phase, 3/4 horsepower general-purpose industrial motor designed for reliable, continuous-duty operation in demanding applications. Operating at 3450 nameplate RPM (3600 Hz synchronous speed) with a 56C rolled-steel frame, this TEFC (Totally Enclosed Fan Cooled) motor delivers consistent performance across a wide range of industrial and commercial environments.
Key Features
- TEFC Enclosure: Totally Enclosed Fan Cooled protection prevents dust and debris ingress, extending motor life in harsh shop and outdoor conditions
- C-Face Foot Mount: Compact configuration with C-face flange and rigid feet allows direct coupling to pumps, gear reducers, and other equipment without adapters
- Dual Voltage: 230V/460V input selection optimizes efficiency and reduces wiring complexity for 3-phase installations
- Continuous Duty Rated: Class B insulation and 74% efficiency at full load ensure reliable 24/7 operation
- Standard Shaft: 5/8-inch keyed shaft fits common pump and mechanical couplings
