High Starting Torque GM2 Motor
1. Jointly developed with USA company
2. Completely interchanageable with original
3. High mechanical efficiency, high starting torque (at startup mechanical efficiency above 0.92)
4. Flat with simple, reliable converters to improve sealing performance, and thus low-speed stability is good, very little leakage. Volumetric efficiency above 0.97
5. Due to the structure to reduce friction losses, improve sealing performance, low-speed stability and thus the motor can operate smoothly 1r/min operating conditions

As piston ring and bearing sleeve through the card firmly affixed there is no gap, so the motor can do pump running conditions, when the inlet is closed motor operating conditions in the free round of high-speed operation
This series motor with the original appearance and installation dimension Italy SAI's basically the same performance parameters and the original fitted Italy SAI close, is an ideal choice to replace imported motor
Features
1. High mechanical efficiency,high starting torque GM Series motors reduce friction loss in force transmission because of no side force between piston and swing cylinder, hydrostatic balance designed in piston foot and transferring torque force through roller bearing. Therefore, GM series hydraulic motors have high mechanical efficiency and high starting torque (above 0.92).
2. High volumetric efficiency The flat distributor is simple, reliable and good seal and theres no leakage between piston and swing cylinder through using plastic seal ring, so motors have high volumetric efficiency.
3. High specific speed range Because of reducing friction loss in configuration and improving seal ability, these motors can run steadily in 1 r/min condition. Moreover, theres no gap between piston and bearing cover connected by ring clip, so they can run with high speed when inlet is sealed and the ratio (max speed) is higher than any other type of equivalent hydraulic motor, giving greater flexibility of application. 4. Minimize heat generation, due to the reduced friction area.
