Introduction
  There-phase induction motors series YZ-H, used for hoisting on board ship are of the squirrel-cage. And recommended for short-time or intermittent drive of the winches and capstans. It has these characteristicses.

    1. The modified YZ-H series has the specialty of interchange with the primary series.
    2. The modified YZ-H series that performance accord with JB5801-1991<the specification of YZ-H series three phase induction motor used for hoisting on board ship>and JB/T7597.1-94<the specification of YZ-H series three phase induction motor used for hoisting on board ship>.
    3. Machinery CO.,LTD take the lead in modifying YZ-H series, HengLi Electric Machinery consulted great successful experience from abroad and integrate strongpoint from native motor into these new series.
    4. The frame and the end-shield of this new series is made of high strength cast iron which has been treated with advanced casting technics. All the mechanical
intensity. Resist-shock and vibration is suitable for the national standard.
    5. The outside of this new series adopted advanced international technics which has introduced three-dimensional geometric figures or bodies technics. Doing this can display the all-round specialty of motors. The looker could enjoy perfect outside when the motor is operating.
    6. The terminal box has been placed on the top of the frame, Doing this can solve the traditional problem that put the terminal box on the right side or left side.
    7. the out surface of the frame is provided with horizontal or vertical cooling ribs to increase cooling effects. the temperature rise could reduce 5~10K comparing to the other motor that has same specification.
    8. The craftwork of the slot match with wire has been optimized and the electric magnet has been improved, therefore the noise has been decreased, It can be
decreased the noise comparing to the other motor that has same specification.
    9. The overall sculpt is perfect and the construction is compact, at the same time the protection is advanced heavily. this kind construction can prevent from coming into water. The safety can be improved greatly.
    10. This new series accord with the requirement of ABS,DNV,LR,NK,KR,RINA except for CCS, as a good saying “A swift horse is fit for a suitable saddle” please Chongqing Bochi believe that the products from BOCHI's could make your equipment running smoothly and perfectly.
