FAQ
▔▔Q1: What is the main difference between Rexroth A2FM and A6VM hydraulic motors?
Answer: The primary difference is displacement type. The A2FM is a fixed displacement motor, meaning its displacement per revolution cannot be adjusted; output speed is varied solely by changing hydraulic flow. The A6VM, on the other hand, is a variable displacement motor, allowing output speed and torque to be dynamically controlled by altering the internal swashplate angle while keeping input flow constant.
Q2: What is the benefit of the bent-axis design in the Rexroth A2FM motor?
Answer: The bent-axis design utilizes tapered pistons arranged at an angle relative to the drive shaft axis. This mechanical configuration provides higher starting torque efficiency, superior overall volumetric efficiency, higher maximum rotation speeds, and better self-priming capability compared to swashplate-type inline axial piston motors.
