Abstract:
The present pump devices provide a dual pump using two (or more) electric motors (e.g. brushless DC motors) driving the pumps independently, including integration of hydraulic and electrical components and connectors. The illustrated arrangements include an in-line single shaft version, a parallel separate shaft version, and an inside-outside version. Each configuration includes a housing supporting formation of: shared structural support for the pumps and motors (e.g., bearings, stator, relationship of components), fluid pump and hydraulic system (e.g., fluid passageways, ports connectors) and motor electrical control (e.g., control circuitry and sensory components).
