Compact power band and flexible voltage support provides 0.5 HP with 3-phase operation and dual voltage of 230 V or 460 V at 60 Hz, reducing spare parts and inventory complexity while aligning to common plant infrastructure. The 56C frame and C-face mounting simplify installation in limited spaces and enable straightforward belt or coupling alignment, speeding up commissioning and retrofit projects. A rugged TENV enclosure with insulation Class F ensures reliable operation in typical factory temperatures up to 40 °C and moderate elevations, while regreasable bearings reduce maintenance intervals and extend service life, lowering total cost of ownership. Direct On Line starting minimizes additional drive components and allows rapid line starts, improving line uptime and overall machine throughput. With a 1.15 service factor and continuous-duty rating, the CNM3539 sustains peak loads in conveyors, pumps, and fans without sacrificing reliability. CSA/UR certification and NEMA alignment provide regulatory confidence for North American installations, while a robust 56C frame supports long-life operation in demanding environments. Finally, consistent speed at 1150 r/min with 1200 r/min synchronous speed delivers predictable torque for precise automation tasks and gear ratios.

FAQs
The CNM3539 supports both foot-mounted base mounting and a C-Face drive-end flange configuration, with a horizontal orientation and F1 mounting position. This provides installation flexibility for compact machines and makes alignment with pulleys, belts, or couplings straightforward, reducing retrofit time and enabling easier integration into existing layouts.
CNM3539 is a 3-phase motor rated for 60 Hz operation with dual voltage support of 230 V and 460 V. It delivers 0.5 HP, uses a 56C frame, and employs a TENV enclosure with insulation class F. It features regreasable bearings (6205 and 6203) and a direct-on-line starting method, with a rated speed of 1150 r/min and synchronous speed of 1200 r/min.
Yes. CNM3539 is designed for continuous duty with a service factor of 1.15, and a 60-minute duty rating support. Its robust 56C frame, 0.5 HP rating, and reliable 3-phase operation make it well-suited for conveyors, pumps, and light machinery where long, uninterrupted operation is required, while maintaining stable torque and temperature under typical loads.
CNM3539 carries CSA and UR certifications and aligns with NEMA design standards, reinforcing regulatory compliance in North American environments. While CE certification isn’t listed in the provided data, the CSA/UR certification and NEMA-compliant design provide strong regulatory confidence for many industrial installations.
Maximize ROI by leveraging regreasable bearings for longer service intervals and reduced maintenance interventions, and by using direct-on-line starting to minimize auxiliary drive components. The motor’s 60 °C ambient rating and 1000 m altitude tolerance support stable performance in typical manufacturing settings, while the 1.15 service factor helps sustain peak loads without premature wear.
