Patent number: 11757317Abstract: A spoked rotor is rotatable about an axis. The rotor includes a core. The core includes a plurality of pole segments arranged arcuately about the axis. The rotor includes a plurality of arcuately arranged magnets alternating arcuately with the pole segments, such that each of the magnets is at least in part interposed between a pair of adjacent pole segments. Each of the magnets includes a curved section extending arcuately between radially inner and outer curved section ends. An effective rotor pole location is defined on each of the pole segments. Each of the pole segments has an end opposite the effective rotor pole location. A center point is defined at the pole segment end. Each of the effective rotor pole locations is arcuately offset from a corresponding one of the center points by between about five tenths (0.5) rotor poles and about two (2.0) rotor poles.Type: GrantFiled: September 28, 2022Date of Patent: September 12, 2023Assignee: Nidec Motor CorporationInventors: Ryan M.

Patent number: 11739759Abstract: A dual motor system includes a first motor providing a lower speed range and a second motor providing a higher speed range, wherein the motors are coaxially arranged and aligned on and drive a common shaft, and a motor control system controlling the speed of the first motor and engaging the second motor as needed. The first motor is a variable speed motor providing a lower two-thirds of a full speed range, and the second motor is an induction motor providing the upper one-third in the form of one or more discrete fixed speeds. The system may include a transformer including a first winding tap which provides a first higher speed, and a second winding tap which provides a second higher speed. The system may also include a flow control system for automatically controlling the speed of the motors for particular applications, such as flow control in a pool.Type: GrantFiled: October 23, 2020Date of Patent: August 29, 2023Assignee: Nidec Motor CorporationInventors: John G.
