In a hydrostatic radial piston motor, the conventional mechanical control of the supply and exhaust of working fluid to the cylinders is replaced by electromagnetic changeover valves which are actuated, in dependence upon the position of the motor shaft 2, by a microprocessor 22. An angle detector 20 cooperating with a toothed ring 19 secured to the motor shaft 2 detects the position thereof. This arrangement allows the energization and de-energization of the valves 14 to be programmed as required in dependence upon the angle of motor shaft rotation. This programmable feature enables the motor to have any required acceleration curve and deceleration curve. <IMAGE> |
