Baldor Electric Company CM3538 AC Induction Motor

Baldor Electric Company's CM3538 is a 1/2 HP, three-phase AC induction motor in a 56C frame with TEFC (totally enclosed, fan-cooled) enclosure designed for continuous-duty industrial use. It operates on 60 Hz power and supports 230/460 VAC, with a synchronous speed of 1800 RPM and a running speed around 1720–1725 RPM, depending on load and tolerance. The motor draws roughly 1.6 A at 230 V (about 0.8 A at 460 V) and carries an efficiency around 75.5% at full load, with UR US agency approvals and Polyrex EM bearing lubrication rated for -20°F to +300°F, and it is specified for ambient temperatures up to 40 °C. The CM3538 features a rigid base and a standard 56C footprint, making it compatible with common Baldor 56C installations. Common applications include general-purpose machinery, compressors, fans and blowers in OEM and retrofit settings, making it suitable for light- to medium-duty industrial tasks.
