Patent number: 11121592Abstract: A rotary electric machine, e.g., a cycloidal reluctance motor, includes a stator having stator teeth connected to a cylindrical stator core, and a rotor having a cylindrical rotor core. The stator core and/or rotor core are constructed of grain-oriented, spirally-wound ferrous material having a circular or annular grain orientation. The stator teeth may be constructed of grain-oriented steel having a linear grain orientation. Notches may be spaced around an inner circumferential surface of the stator core, with each stator tooth engaged with a respective notch. The rotor may be eccentrically positioned radially within the stator. The rotor core may define notches spaced around its outer circumferential surface, with salient rotor projections engaged with a respective rotor notch. The machine in such an embodiment may be a switched reluctance rotor. An electrical system using the machine and a method of manufacturing the machine are also disclosed.Type: GrantFiled: April 8, 2019Date of Patent: September 14, 2021Assignee: GM Global Technology Operations LLCInventors: Alireza Fatemi, Derek F.

Patent number: 10955025Abstract: A vehicle powertrain variable vibration absorber assembly can be equipped in a hybrid electric vehicle (HEV). The vehicle powertrain variable vibration absorber assembly includes a rotary device, a drive-ratio assembly, and a spring. The rotary device, in an example, is a motor-generator unit (MGU). The drive-ratio assembly, in an example, is a planetary gear assembly. The drive-ratio assembly receives rotational drive input from the rotary device, and transmits rotational drive output to a powertrain component. The spring, in an example, is a variable stiffness spring. The spring is connected to the drive-ratio assembly and is connected to a grounded component. During use, the vehicle powertrain variable vibration absorber assembly absorbs different frequencies of vibration brought about by a vehicle engine amid different operating modes. The operating modes can involve cylinder deactivation technologies.Type: GrantFiled: May 31, 2018Date of Patent: March 23, 2021Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Derek F.
