Description
The variable displacement motor was designed especially for hydrostatic drives with secondary control.
A complete control assembly for a maximum swivel range of Vmax/Vmin=3.47 is fitted.
Special Characteristics:
Large control range with hydrostatic transmissions
Secondary control regulation with various control devices
Increased maximum output speeds at reducing swivel angle
Cost-saving due to the possibility of using smaller pumps
Obviates the multi-speed  ratio gear drives
High power density
Optional mounting position
High efficient
Excellent starting characteristics
Low inertia
