K4VSM series axial piston variable motor is specially designed for high-pressure engineering machinery. The engine is an oblique axial piston pump with a spherical valve, large runner and shaft drive. The product is suitable for open and closed-circuit hydrostatic drive.

Features

Through shaft variable displacement piston motor, high rigidity casing and integral swash plate, specially designed for hydrostatic drive in open and closed circuits
Flow proportional to speed, suitable for variable speed drive
Proportional speed regulation motor, electronically controlled to adjust the cradle which can steplessly change the output speed
100% torque transmission through the shaft for mounting additional pumps
High power/weight ratio
Steplessly variable spherical flow, displacement from 50% Vmax to Vmax
Swashplate angle indicator, observe the working state of the pump directly
Suitable for drives that need high reliability, high pressure, long service life and wide speed range
