ABSTRACT:
A modular dynamometer includes a stator mounted to and disposed within a housing and the combustion of a shaft and a rotor also disposed within the housing. The shaft extends through the housing and is adapted for coupling to a prime mover. The housing is closed and is filled with a liquid coolant, such as water. Lateral panels of the housing may be removed after the coolant is drained out to permit one or more rotor/stator combinations to be positioned within the housing along the rotating shaft in an alternating manner. The rotors are attached to the shaft so as to rotate therewith, while the stators are mounted to the housing in a fixed manner. Rotor/stator modules may be easily added to or removed from the dynamometer to facilitate increasing or decreasing the dynamometer capacity permitting the modular dynamometer to test a wide range of prime mover output power.
