ELECTRONIC CONTROL FOR A ROTARY FLUID DEVICE

摘要

A fluid device system includes a rotary fluid device (18). The rotary fluid device (18) includes a housing (28) having a main body (34) with a first end portion (36) and an opposite second end portion (38). The first end portion defines a first chamber (44) and the second end portion defines a second chamber (48). A fixed displacement pumping assembly (56) is disposed in the first chamber of the first end portion. An electric motor (24) is disposed in the second chamber of the second end portion. The electric motor includes a shaft (26) that is coupled to the pumping assembly. The fluid device system further includes a plurality of sensors (102) that is adapted to sense operating parameters of the rotary fluid device and a controller. The controller (20) is in electrical communication with the electric motor of the rotary fluid device and the plurality of sensors. The controller includes a microprocessor (116) and a storage media (118). The storage media is in communication with the microprocessor and includes at least one lookup table (120) that includes performance characteristics of the rotary fluid device. The lookup table is used by the controller to achieve a desired attribute of the rotary fluid device.
