Patent number: 9270212Abstract: An electric motor has a control circuit that enables an operational speed of the electric motor to be selected with reference to multiple ranges of speeds and the input voltage to the motor. Switching between speed ranges occurs in response to activation of a switch or in response to expiration of a time period set by a selector switch.Type: GrantFiled: March 11, 2014Date of Patent: February 23, 2016Assignee: Merkle-Korff Industries, Inc.Inventors: Robert Hollenbeck, Bruce Ley, Trevor Perdue, Bart Long, Justin Mumaw

Publication number: 20140271280Abstract: An electric pump motor is provided. The motor includes a stator assembly including a magnetic stator component and an overmolded stator casing sealingly encapsulating the magnetic stator component. A rotor assembly that is rotatable about an axis includes a rotor shaft extending along the axis, a magnetic rotor component, and an overmolded rotor casing fixedly interconnecting the rotor shaft and magnetic rotor component. The rotor shaft is connected to an impeller that imparts a thrust load on the rotor shaft. The rotor and stator assemblies are configured so that the magnetic components induce a solenoid force on the rotor shaft opposite the thrust load.Type: ApplicationFiled: March 17, 2014Publication date: September 18, 2014Applicant: MERKLE-KORFF INDUSTRIES, INC.Inventors: Bruce Ley, Justin Mumaw, Justin Anteau

Patent number: 6573670Abstract: A vending machine includes a gearmotor with feedback control allowing for the determination and control of the axial rotational position of the gearmotor's output shaft. The gearmotor has a DC motor, gear train, at least one rotation sensing mechanism and control circuitry. The rotation sensing mechanism is in operative connection with the output shaft of the gearmotor and/or the armature shaft of the motor such that the feedback provided by the sensor allows the control circuitry to determine the position of at least one of the shafts and, based on that determination, control the output of the motor to either stop rotation or produce additional rotation as necessary to properly dispense product of varying sizes based on pre-programmed data regarding the desired rotation for various products. A method for controlling the dispensing of products in a vending machine is also disclosed.Type: GrantFiled: July 10, 2001Date of Patent: June 3, 2003Assignee: Merkle-Korff Industries, Inc.Inventors: Kevin J. Machalek, William C. Hittie, Jr.
