What type of fluid power motor provides constant torque and speed output in either direction?

A fluid power motor that provides constant torque and speed output in either direction is a fixed motor. Fixed motors are designed to deliver a consistent performance, meaning they can maintain set levels of torque and speed regardless of changes in load or direction. This characteristic makes them ideal in applications where precise and steady operation is required, such as in certain automated machinery or conveyor systems.

Regarding the options that do not correctly describe this type of motor: bidirectional motors allow for movement in both directions but don't necessarily guarantee constant torque and speed; variable motors change their output based on control signals, often resulting in fluctuating performance; and double-acting refers to the mechanism by which pressure can act on both sides of a piston, which does not imply a constant torque and speed output. Therefore, focusing on the features of fixed motors explains why they are the accurate choice in this context.
