YZRDW（F）、YZRSW（F）series eddy current brake wound rotor three-phase asynchronous motor for tower hoisting
YZRDW (F) and YZRSW (F) series eddy current brake wound rotor two-speed three-phase asynchronous motors are specially developed for the lifting mechanism of large and medium-sized tower cranes and other similar equipment. It has the characteristics of smooth speed regulation, small starting current, strong overload capacity, high mechanical strength, low temperature rise and high reliability, especially suitable for those short-time or intermittent operation, frequent starting and braking, sometimes overload and significant vibration and shock equipment.
