Three Phase Asynchronous Motor
Overview:
Greensky three phase asynchronous motors use a squirrel-cage rotor to convert 3-phase AC power into stable rotary output. Standard TEFC construction, IEC frame sizes, IE2/IE3 efficiency and flexible mounting (B3/B5/B14/B35) make them suitable for pumps, fans, compressors, conveyors, machine tools and general industrial drives. Voltage, frequency, pole count, enclosure and shaft options can be customized to match existing equipment. [3,4](@ref) Learn more about our squirrel-cage asynchronous motors.
