What will happen to the speed and torque of an in-line axial piston motor if the swash plate is set nearly straight up and down?

When the swash plate of an in-line axial piston motor is set nearly straight up and down, the motor is configured in such a way that it maximizes the angle relative to the pistons, which significantly influences the mechanical output. In this position, the pistons travel a shorter stroke during their rotation, which leads to a higher speed of operation because the pistons can cycle through their movements more quickly.

At the same time, the torque generated by the motor is impacted by this configuration. Since the pistons are operating with a reduced stroke length because of the nearly vertical swash plate, the force exerted by the pistons results in lower torque output. This relationship between speed and torque is fundamental in understanding how the swash plate angle affects performance. Therefore, the motor will operate at high speed due to the quicker cycling of the pistons, but the torque produced will be lower because the effective stroke length is minimized.

This results in a scenario where the motor achieves high speeds while producing low torque, which accurately corresponds to the characteristics of the system when the swash plate is set nearly upright.
