All the energy is transformed into rotary motion device is called motor. Hydraulic motor is the pressure of the liquid medium can be converted into rotating movement.
1, the hydraulic system has the characteristics of the energy density is big, the same power of motor, hydraulic motor is much smaller than motor, much lighter. Ease of applications on mobile devices.
2, hydraulic motor is easy to control, rely on the adjustment of the hydraulic valve, can promise between 0 and maximum speed adjustment, the motor itself does not need special design, the cost is low. Than the motor + reducer, or frequency conversion motor, servo motor much cheaper.
3, hydraulic motor is totally enclosed, in the dust, moisture (underwater), combustible environment can be at ease use, explosion-proof (FLP) motors are more reliable.
4, hydraulic pressure system of the overload resistance is very strong, rely on the protection of the overflow valve, allowing for a long time (relative), frequent overload, and under overload condition is very easy to recover, not damage the equipment, also do not need to restart your device.
