Abstract
A method of urging rotation of an output shaft comprises delivering fluid to a motor coupled to the output shaft. The motor has a housing and at least one first chamber in the housing. The method further comprises operating the motor in a positive displacement mode for at least a first period of time and in a turbine mode for at least a second period of time to transfer energy from the fluid to rotation of the output shaft about its longitudinal axis.
