FAQs
BM3539 is designed for 56 frame size, foot-mounted installation, and TEFC enclosure motors. It supports direct connection to 3-phase, 230/460 V systems at 60 Hz, with a horizontal mounting orientation (F1) and standard drive-end flange. This compatibility streamlines retrofits and OEM integrations, minimizing custom mounting without sacrificing clearance or service access.
BM3539 operates at 60 Hz with a voltage rating of 230 V / 460 V and is a 3-phase device. It provides a rated current of 2.4 A (high) and 1.2 A (low) and offers a 0.5 HP output at a rated speed of 1140 r/min. The brake is regreasable, and the service factor is 1.25, supporting reliable performance under variable loads.
Yes. The design uses regreasable lubrication to support long service life in high-cycle environments. It features a robust steel frame with TEFC protection and a 56 frame size for straightforward mounting. Stocked at multiple warehouses, lead times are minimized, and routine maintenance tasks are simplified by accessible lubrication points and standard mounting hardware.
BM3539 carries CSA and UR certification, aligning with recognized safety standards. It also adheres to NEMA design guidelines and uses a TEFC enclosure. These certifications help ensure compliance in North American facilities and support integration with standard industrial drives and motor assemblies.
The BM3539 delivers predictable braking performance with low maintenance, reducing unexpected downtime. Its compact 56-frame, foot-mounted design minimizes installation time, while regreasable bearings and stock-ready availability shorten service windows. Combined with a service factor of 1.25 and high compatibility with 230/460 V systems, it provides a favorable total cost of ownership over time.
