The high-speed hy motors gear motor has the advantages of small size, light weight, simple structure, good maneuverability, insensitivity to oil contamination, impact resistance and low inertia. Disadvantages include large torque ripple, low efficiency, low starting torque (only 60% of rated torque - 70%) and poor low speed stability.
We have the brand as following: Komatsu; Hitachi; Caterpilliar; Kobelco; Case; Sumitomo; JCB; Volvo; SANY; Liugong; XCMG; XGMA and so on.

The hy motors is an actuator of the hydraulic system that converts the liquid pressure energy provided by the hydraulic pump into the mechanical energy (torque and speed) of its output shaft. Liquid is the medium that transmits force and motion. 

Hydraulic motors, there are travel motor, swing motor, rotary motor, which are also known as oil motors, are mainly used in injection molding machinery, ships, hoists, construction machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, marine machinery, petrochemical, port machinery, etc.

From the point of view of energy conversion, the hydraulic pump and the hydraulic motor are reversible hydraulic components. The input of working fluid to any hydraulic pump can make it into a hydraulic motor condition; otherwise, when the main shaft of the hydraulic motor is external When the torque is driven to rotate, it can also be changed to the hydraulic pump working condition. Because they have the same basic structural elements - a closed and periodically variable volume and corresponding oil distribution mechanism. However, due to the different working conditions of the hydraulic motor in series and the hydraulic pump, their performance requirements are different, so there are still many differences between the same type of hydraulic motor and hydraulic pump. First of all, the hydraulic motor should be able to be positive and reverse, thus requiring its internal structure to be symmetrical; the speed range of the hydraulic motor needs to be large enough, especially for its minimum stable speed. Therefore, it usually uses a rolling bearing or a static pressure sliding bearing; secondly, the hydraulic motor does not have to have self-priming capability because it operates under the input pressure oil condition, but requires a certain initial sealing property to provide the necessary starting torque. Due to these differences, the hydraulic motor and the hydraulic pump are similar in structure but cannot be reversible; if you want to do hydraulic motor repair and hydraulic pump repair, you should pick up us.
