Neural Network And Method For Estimating Regions Of Motor Operation From Information Characterizing The Motor
Christopher Allen Hudson - Blacksburg VA, US Nimal Lobo - Blacksburg VA, US Krishnan Ramu - Blacksburg VA, US
Assignee:
Virginia Tech Intellectual Properties, Inc. - Blacksburg VA
International Classification:
B25J 9/18 G05B 19/19
US Classification:
31856811, 318620, 318623, 700 48, 701 59
Abstract:
A method for collecting operational parameters of a motor may include controlling the energization of a phase winding of the motor to establish an operating point, monitoring operational parameters of the motor that characterize a relationship between the energization control applied to the motor's phase winding and the motor's response to this control, and collecting information of the operational parameters for the operating point that characterizes the relationship between the applied energization control and the motor's response. The collected information characterizing the relationship between the applied energization control and the motor's response may be employed by a neural network to estimate the regions of operation of the motor. And a system for controlling the operation of motor may employ this information, the neural network, or both to regulate the energization of a motor's phase winding during a phase cycle.

Apparatus And Method That Prevent Flux Reversal In The Stator Back Material Of A Two-Phase Srm (Tpsrm)
Krishnan Ramu - Blacksburg VA, US Nimal Lobo - Blacksburg VA, US
International Classification:
H02K017/00 H02K017/42
US Classification:
310/166000, 310/168000
Abstract:
A TPSRM may include a stator, having a plurality of poles and a ferromagnetic or iron back material, and a rotor having a plurality of poles and a ferromagnetic or iron back material. A current flowing through coils wound around a first set of the plurality of stator poles induces a flux flow through the first set of stator poles and portions of the stator back material during a first excitation phase. A current flowing through coils wound around a second set of the plurality of stator poles induces a flux flow through the second set of stator poles and portions of the stator back material during a second excitation phase. The numbers of stator and rotor poles for this TPSRM are selected such that substantially no flux reversal occurs in any part of the stator back material as a result of transitioning between the first and second excitation phases.
