Replace Rexroth A2FM Series Hydraulic Motor Working Principle:

Core Structure：Composed of bent-axis cylinder block, 9 pistons, connecting rods, valve plate, and output shaft; the cylinder block has a fixed 23° angle with the output shaft.
Energy Conversion：High-pressure oil enters the piston cavity via the valve plate→drives the piston to reciprocate→the connecting rod converts linear motion into rotational motion of the output shaft (hydraulic energy → mechanical energy).
Stable Output Logic：The fixed-displacement structure ensures constant displacement; torque is proportional to system pressure (T=ΔP×V×ηₘ/2π), outputting ultra-high torque at low speed without crawling.
Bidirectional Operation：Forward/reverse rotation is achieved by switching the oil inlet direction; the bidirectional torque deviation is ≤±2% with response speed ≤0.1s.
