This shows that the variable speed variator can help to simplify the variable driving scheme to improve lab or productivity and product quality, and to take use of motive power and save energy reasonably. Meantime it has the following merits:
1.MB seires variable speed variator has a high precision of revolution,and it  is the range of speed regulating precision of regulating speed, the best one in the same kind of products.
2.Large speed regulating range:The regulating range of MB series variable speed variator is Rb=5.
3.All driving mediums of the series of products are stictly treated, finely processed and grinded with good performances of contact and lubrication.So it can run stable with low nosie and long use life.
4.The best feature of MB series variable speed variator is that it can be effectively combined with all kinds of gear reducers, cycloid reducers and worm reducers, thus the output torque is enlarged , and the lowest and highest output rotary speed  at various situations are realized, so the variable speed variator  has good suitablity.
5.The output torque and power of  MB series variable speed variator changes with output revolution. Its mechanical features are changeable torque and changeable power.
