USED ASYNCHR.MOT. MB63A/4

The MB63A/4 is an IEC Frame 63, 4-pole three-phase asynchronous (squirrel cage induction) electric motor designed for continuous industrial duty. The model designation follows standard European IEC nomenclature: Frame 63 (63mm shaft centre height), size A (smallest in the 63 frame family), and /4 indicating 4-pole configuration for approximately 1400 RPM at 50Hz. This compact motor features an aluminium frame construction, foot mount base, keyed shaft, and IP55-rated TEFC enclosure suitable for light industrial drive applications including conveyors, fans, pumps, and small machinery where reliable low-power AC drive is required.
