Abstract: A reconfigurable rotating electric machine having a rotor to rotate in association with a stator. Coils are arranged to form the windings of one or more phases. Each coil or group of coils has a pair of terminals to receive an electrical input. Switches are arranged to connect each coil or group of coils in series or parallel with another coil or group of coils to form defined coil topology configurations. A processor has memory storing settings to determine a state of each of the switches for each of the defined coil topology configurations. The switches are controllable to connect the coils into a force expansion topology configuration to form an electrical machine having two, four, or more virtual poles.

Abstract: Disclosed herein are embodiments of novel WPT systems, devices, and methods of using the same. Also disclosed herein are methods for controlling the power delivered from a stationary source (e.g., a primary coil) to a moving telemetric device (e.g., a secondary coil) via magnetic resonance coupling. The systems, device, and methods described herein can be used to tune and/or detune resonant frequency between a primary coil and a telemetric device so as to prevent device malfunction and/or tissue damage for the small animals associated with the telemetric device.

Abstract: Disclosed herein are embodiments of a novel WPT system to deliver power from a stationary source (e.g., a primary coil) to a moving telemetric device (e.g., a secondary coil) via magnetic resonance coupling. Novel configurations of the secondary employing ferrite components placed at specific locations and orientations within the coil. Embodiments of these secondary coil configurations are constructed and their performance is tested. Measurements show that ferrite components improved power transfer at most orientations, beyond that of the nominal ferrite-less configuration. The use of angled ferrite components further improved power transfer.
