NEMA Standard Three-Phase Asynchronous Motors are totally enclosed fan-cooled motors. This series of motors is designed and manufactured according to the U.S. NEMA standards. NEMA standard motors are available in four designs: A, B, C, and D. Our company has designed NEMA standard high-efficiency three-phase asynchronous motors and NEMA standard high starting torque, high slip three-phase asynchronous motors based on market demand.

NEMA Standard High-Efficiency Three-Phase Asynchronous Motors (Design B):
This series of motors adopts F-class insulation and has a protection class of IP54 (IP55). The service factors are 1.0, 1.15, and 1.25. The voltage levels are 230/460V, 460V, or 575V, with a rated frequency of 60Hz. The operating temperature range is -15~40°C, and the altitude does not exceed 3300 feet. These motors are suitable for general applications without special requirements and can be used as power units for various mechanical equipment.

This series of motors can be specially manufactured according to user requirements.
