Patent number: 9240749Abstract: A control system for a motor includes a pulse-width modulation module, a pulse skip determination module, and a duty cycle adjustment module. The pulse-width modulation module generates three duty cycle values based on three voltage requests, respectively. A plurality of solid-state switches control three phases of the motor in response to the three duty cycle values, respectively. The pulse skip determination module generates a pulse skip signal. The duty cycle adjustment module selectively prevents the plurality of solid-state switches from switching during intervals specified by the pulse skip signal.Type: GrantFiled: August 9, 2013Date of Patent: January 19, 2016Assignee: Emerson Climate Technologies, Inc.Inventors: Charles E.

Publication number: 20150381090Abstract: A system and method for determining electrical angles of electric motors at zero and low speeds without using angle sensors, and a system and method for estimating resistances and temperatures in electric motors, wherein the two systems and methods may be used separately or together. When used together, they substantially simultaneously estimate motor flux linkage, magnet flux, and motor resistance. In particular, the estimated magnet flux is used to derive the electrical angle and to estimate an average rotor temperature, and the estimated motor resistance is used to estimate the average stator temperature. A Kalman filter, which may be a linear Kalman filter or a Luenberger observer, is used to update state equations from which various motor parameters can be derived or estimated. The system and method which works for motors operating at zero and low speeds can be combined with systems and methods that work at high speeds.Type: ApplicationFiled: June 25, 2015Publication date: December 31, 2015Applicant: NIDEC MOTOR CORPORATIONInventors: Michael I.

Patent number: 8547051Abstract: A system includes a control module that controls a motor based on a first rotor angle and an angle determination module that generates the first rotor angle. An estimator module determines an estimated rotor angle of the motor. A transition module generates a transition signal in response to convergence of the estimator module. The angle determination module initially generates the first rotor angle based on an open loop angle. In response to the transition signal, the angle determination module switches to generating the first rotor angle based on the estimated rotor angle and an offset value. The offset value is based on a difference between the estimated rotor angle and the open loop angle at the time when the transition signal is generated.Type: GrantFiled: August 15, 2012Date of Patent: October 1, 2013Assignee: Emerson Climate Technologies, Inc.Inventors: Charles E.
