I. Selection principle of motor protectorThe  Electric Motor Manufacturer   stated that the reasonable selection of the motor protection device can not only fully utilize the overload capability of the motor, but also avoid damage, thereby improving…

The small-displacement supercharged motor replaces the large-displacement motor with the speed of lightning, and the motor of 2.0L or above is the “large displacement” in the moment. More and more vehicles are merged into small-displacement motors. T…

The cycloidal hydraulic motor is a small low-speed, high-torque hydraulic motor with a shaft-distributed insert and stator-rotor pair. How to deal with the failures often occurring in the use of cycloidal hydraulic motors, the    Hydraulic Motor manu…

Crank connecting rod type low speed high torque hydraulic motor is used earlier, which is called Staffa hydraulic motor abroad. JMZ, the same type in China, has the rated pressure of 16MPa, the highest pressure of 21MPa and the maximum theoretical di…
