Patent number: 10228663Abstract: Apparatus are provided for motor control systems and related medical devices. In one embodiment, a control system includes a motor having a rotor, a sensor to obtain a measured displacement that is influenced by rotation of the rotor, and a control module coupled to the sensor. The control module adjusts a duty cycle for a modulated voltage applied to the motor in response to a difference between an expected displacement and the measured displacement. The expected displacement is influenced by or otherwise corresponds to a commanded rotation of the rotor.Type: GrantFiled: May 23, 2016Date of Patent: March 12, 2019Assignee: Medtronic MiniMed, Inc.Inventor: Jacques L. Favreau

Patent number: 10145710Abstract: A motor may be configured to drive a drive shaft and an engagement member supported on the drive shaft. A detectable feature comprising a rotary member may be supported on the drive shaft such that movement of the drive shaft by the motor changes a state of the detectable feature. At least one sensor may be arranged to detect the state of the detectable feature. Circuitry may be configured to provide a signal in response to a change in the state of the detectable feature detected by the at least one sensor.Type: GrantFiled: February 13, 2014Date of Patent: December 4, 2018Assignee: Medtronic MiniMed, Inc.Inventors: Ian B. Hanson, Paul F. Bente, IV, Jacques L. Favreau, Lothar Westerweck
