　　As the hydraulic coupler i=0, make input characteristic curve intersected with its maximum torque point, in order to facilitate with maximum torque load motor.

　　The overload coefficient of cam and groove coupling is lower than motor's overload coefficient, in order to protect the motor from damage.

　　Let motor power left a certain margin. If the working shaft power of 1, then the power ratio of the work machine, cam and groove coupling and motor is 1:1,05:1.1 as well.

　　You try to use power limit. The torque limited cam and groove coupling transmission power upper limit corresponding to the 80% liquid filling, corresponding to the 50% liquid filling rate power transfer limit. Because of the performance curve of high filling rate performance curve is better than the low filling rate, and high filling rate at narrow unstable region coupling, so should try to choose the small size, high ratio of liquid cam and groove coupling, and don't choose the low filling rate, the larger size of cam and groove coupling. Characteristics of hydrodynamic coupling charging and power transfer paper please see: hydraulic cam and groove coupling liquid filling degree to transfer power.

　　Hydraulic cam and groove coupling does not have motor protection overload drop functionality, so when the motor is under low voltage operation in a long time to match cam and groove coupling, you should pay attention to overload protection. Data show that, the voltage drop of 10%, running at full capacity, motor is overload but cam and groove coupling is not overloaded, and thus will not cause the heat spraying, motor protection. The solution is to reduce the liquid coupling rate, reduce the output torque, so that it can protect the motor can not be burned in overload.
