Feature: The motor operates on a simple single‑phase 115/230 V supply at 60 Hz, delivering 0.75 HP. Business Impact: This dual‑voltage capability reduces panel design complexity and inventory for regional sites while keeping installation straightforward. Application: Suitable for direct‑drive fans, small conveyors, and process equipment in agriculture, HVAC, and industrial environments. Feature: TEAO enclosure and 56YZ frame maximize airflow and durability in harsh environments. Business Impact: Improves reliability in heat‑soaked spaces and mitigates enclosure overheating, while maintaining compatibility with standard mounting patterns for retrofit projects. Application: Ideal for direct‑drive fans and compact industrial machinery in pubs, greenhouses, and processing lines. Feature: Resilient mounting and horizontal orientation minimize vibration and simplify alignment. Business Impact: Reduces operator maintenance, belt wear, and machine downtime, delivering longer service intervals. Application: Suited for horizontal installations in space‑constrained equipment and retrofits in existing lines. Feature: Regreasable bearings (6203) and direct‑on‑line starting support easy maintenance and predictable life cycles. Business Impact: Lower total cost of ownership through extended bearing life and simpler lubrication routines. Application: Effective in remote plants and service‑heavy environments where downtime is costly. Feature: RoHS compliance, CSA/UR certification, and NEMA compatibility provide procurement confidence and regulatory alignment.

FAQs
Plan for horizontal mounting in an F1 orientation using the resilient base. The 56YZ frame and TEAO enclosure provide a compact footprint with easy retrofitting into existing equipment. The motor is designed for direct drive and simple wiring, minimizing cabinet space and wiring complexity while maintaining vibration control and alignment stability.
Key specs include 0.75 HP output, 1700 r/min nominal speed, 1 phase operation at 115/230 V, and a service factor of 1.15. The motor supports direct on line starting and a power factor around 92%, making it well suited for small fans, conveyors, and process cooling in light industrial settings.
Yes. The CHC445A series is RoHS compliant and carries CSA/UR certification, with NEMA compatibility. These certifications support regulatory compliance in North America and simplify supplier qualification for regulated industries, while ensuring safe operation in harsh environments from greenhouse to factory floors.
The motor uses regreasable bearings (6203, ball). Follow a scheduled lubrication interval per maintenance programs to optimize bearing life. This approach reduces unexpected downtime, extends service life, and lowers long‑term replacement costs, especially in remote or high‑heat installations where lubrication access may be limited.
ROI improves through reduced downtime, easier installation, and lower spare parts inventory thanks to dual voltage operation, a TEAO enclosure, and a resilient mount. The combination of a 1.15 service factor and high reliability translates to fewer maintenance events, longer intervals between replacements, and faster project payback in continuous‑duty farm and industrial cooling applications.
