YZTD2YZTD2 Series Multi-Speed Three-Phase Asynchronous Motors for Tower Crane Hoisting
Tower Crane Motors YZTD2 JANGTE
YZTD2 motors are multi-speed squirrel-cage motors for the hoisting mechanisms of small and medium tower cranes. Speed is changed by pole switching with a wide ratio between steps, giving a wide control range, low starting current and high starting torque. There are no brushes and no separate speed controller. Ratings: 15–24 kW, frames 180–225, 380 V, 50 Hz, IP44, class F, IC411, IM B3; duty S3-40 % at high and medium speed, S3-25 % at low speed. Jiangte took part in drafting the JB/T 8956 industry standard for YZTD(E) motors.
