Patent number: 10284128Abstract: A motor includes a stator comprising windings configured to be energized, and a rotor electromagnetically coupled to the stator and configured to turn relative thereto when the stator is energized. The motor also includes a motor controller configured to measure a speed at which the rotor turns, and energize said stator to generate a first torque output at the rotor when the measured speed is below a first threshold. The motor controller is also configured to energize the stator to generate a second torque output at the rotor when the measured speed is at least the first threshold, wherein the second torque output is greater than the first torque output.Type: GrantFiled: June 20, 2017Date of Patent: May 7, 2019Assignee: Regal Beloit America, Inc.Inventors: Andrew Craig Barry, Brian Lee Beifus, Lester Benjamin Manz, Kamron Mark Wright

Publication number: 20160161317Abstract: Aspects of the disclosure are directed to estimating the fuel consumption of a vehicle. As may be implemented in accordance with one or more embodiments, fuel consumption of a vehicle's combustion engine is estimated during operation of the combustion engine with a particular fuel type. A value for air flow through the combustion engine is obtained. An amount of oxygen that is burned during operation of the combustion engine is determined by, based upon the value for the air flow, estimating the quantity of oxygen flowing through the combustion engine, and estimating the amount of the oxygen flowing through the combustion engine that is unburnt. The fuel consumption is then estimated based upon the determined amount of oxygen that is burned and the fuel type.Type: ApplicationFiled: August 27, 2015Publication date: June 9, 2016Inventors: John Keates, Glen Tunstall, Craig Barry
