Farm-duty design with 0.5 HP output delivers reliable direct-drive cooling for barn ventilation and light industrial fans, reducing system complexity and downtime. The 60 Hz, 230/460 V three-phase supply aligns with standard facility power, simplifying procurement and wiring while supporting consistent airflow. The 1725 rpm nominal speed enables predictable performance across a broad range of applications, lowering the risk of under- or over-driving fans. TEAO enclosure protects bearings and windings from dust and moisture, improving longevity in harsh environments, while the resilient base and horizontal mounting simplify installation and retrofit work, saving time and cost. With a 4-pole rotor and 1.25 service factor, you gain stronger starting torque and reserve capacity for load transients common in cooling and ventilation loads. The motor is RoHS compliant and carries CSA/UR certifications, helping ensure regulatory alignment for international projects. Finally, the 48YZ frame and bearing assembly support straightforward maintenance and part availability, reducing total cost of ownership over the motor’s life.

FAQs
The 7BCHM344A uses a resilient mounting base with a horizontal F1 orientation for straightforward installation. It is a 3-phase motor compatible with 230 V or 460 V supplies, designed for direct-wiring connections in standard industrial control circuits. This configuration supports quick retrofits and minimizes wiring complexity during commissioning or replacements.
The motor is a 4-pole design delivering 1725 rpm nominal speed with a synchronous speed of 1800 rpm at 60 Hz. It operates on 230 V or 460 V three-phase power and achieves about 66% efficiency. The rated current is 2.2 A, and it carries a service factor of 1.25, providing steady torque under load and some headroom for transient conditions.
Yes. Its farm-duty rating, TEAO enclosure, and 0.5 HP output are ideal for direct-drive fans and ventilation blowers in barns, greenhouses, and light industrial settings. The 48YZ frame and resilient mount simplify mounting, while the 3-phase, 230/460 V operation supports common electrical infrastructure in these environments.
The motor carries CSA/UR certification and is RoHS compliant, aligning with international safety and environmental requirements. It is built to NEMA standards with a Design B designation, ensuring reliable torque and start characteristics for continuous duty in mixed indoor/outdoor environments.
Regreasable bearings (6203) and a TEAO enclosure reduce contamination and maintenance needs, extending service life. The 1.25 service factor and 66% efficiency translate to better total cost of ownership, with lower energy consumption per unit of airflow and predictable performance, supporting lower maintenance intervals and faster return on investment in HVAC and process cooling applications.
