FAQs
The 7BCHM545A uses a 56YZ frame with horizontal mounting and F1 mounting position for easy integration into existing assemblies. It features a resilient base and 0.63 in shaft diameter, enabling straightforward retrofit into compact spaces while maintaining alignment with 3-phase, 60 Hz power supply. This combination minimizes modification work during installation.
This motor is a three-phase unit rated for 208-230/460 V at 60 Hz, delivering 1 HP with a rated speed of 1725 r/min. The rated current is 3.4 A at lower voltages and 1.7 A at higher voltages, and it uses a TEAO enclosure with regreasable 6203 ball bearings to support reliable operation.
Yes. It is designed for continuous duty with a service factor of 1.15, a 4-pole configuration yielding near 1725 r/min, and a TEAO enclosure suitable for ventilating and cooling fans. The motor’s construction and bearings support long run times in harsh environments, while its compact form factor simplifies installation in retrofit projects.
The 7BCHM545A carries CSA | UR certification and RoHS compliance, along with a NEMA design B designation. These credentials support regulatory compliance, safer handling, and predictable performance in North American and global installations, aiding procurement and QA workflows.
Regreasable bearings (6203) and a robust direct-drive design reduce belt wear and maintenance intervals, lowering downtime and operation costs. The motor’s 1 HP rating, 60 Hz operation, and durable frame help stabilize energy use and reliability in long-running cooling or ventilation applications, contributing to improved total cost of ownership.
