20090237037 - Alternator voltage regulator with maximum output limiting function: An alternator system includes a field circuit, a regulator that regulates a field circuit electrical flow through the field circuit, and an output current sensor that detects an actual current output from the alternator system. The alternator system further includes a controller that communicates with the regulator to vary the... Agent: Harness, Dickey & Pierce, P.L.C

20090237038 - Double alternator and electrical system: A double alternator system includes a first brushless winding assembly to generate a first electrical voltage, a second winding assembly to generate a second electrical voltage, a rotatable shaft common to the first brushless winding assembly and second winding assembly to cause generation of a first electrical voltage and second... Agent: Adams Intellectual Property Law, P.A.

20090230927 - Fault clearing method for permanent magnet machines: A permanent magnet machine (PMM) has a kinetic portion electrically coupled to a power conversion portion. Motive power is provided to the kinetic portion by a torque applied to a motive shaft coupled to a prime mover, such as an aircraft engine or an automobile engine. A control circuit includes... Agent: Wiggin And Dana LLP Attention: Patent Docketing

20090230928 - Connecting a prime mover driven alternator to a circuit with an existing alternating current: Apparatus and method are provided, for connecting prime mover driven alternator to circuit that has an existing alternating current. Alternator is connected to circuit when minimum current flows to or from alternator. The actual current is measured by controller following connection and the value of this current is used to... Agent: Ballard Spahr Andrews & Ingersoll, LLP
