M3B Series Motor
Axial Piston Motors, Variable Displacement, Swash Plate.
This series consists of variable displacement axial piston motors of swash plate design for winch application. These motors have a good self-priming capability and high starting efficiency developed based on our many years of experience and technology obtained in swash plate type pumps and motors. By combining the reduction gear RG series and M3B series, they provide to cover up large capacity.
The M3B Series have the same rotary components of M3X Series which enable the advanced low-speed characteristic and high-speed operation.
The design of various displacement control is based on the current MB Series. The range of displacement is 100%–33% with three types of various displacement control regulators. Electric displacement control is also possible.
