Patent number: 10658902Abstract: An axial brushless DC motor comprising a stator, a rotor including a magnet, a sleeve bushing extending through the stator and including a pair of opposed distal collars, a motor shaft extends through the sleeve bushing, and a pair of opposed bearings are seated in the respective pair of collars and mount the shaft and a rotor for rotation relative to the sleeve bushing and the stator. The bearings are adapted for thrust, radial support/self-alignment, and angular adjustment of the motor shaft. In one embodiment, a stator overmold member includes a central tube that defines the sleeve bushing and includes a stator shorting ring. In one embodiment, a metal pole piece is seated in a cup-shaped magnet with a rim and the magnetic flux travels through the rim of the magnet and through a magnetic flux sensor.Type: GrantFiled: November 30, 2018Date of Patent: May 19, 2020Assignee: CTS CorporationInventors: Yulanda Y H W King, David Kolberg, Douglas E.

Publication number: 20190078910Abstract: A vehicle component actuator comprising a housing, an actuator motor in the housing, and a rotatable output gear shaft assembly in the housing including a rotatable output shaft and gear. The output gear includes one or more discontinuities defined therein and each presenting a magnetic flux signature. A position sensor, including for example a Hall Effect position sensor with an integrated magnet, senses the magnetic flux signature of the one or more discontinuities on the output gear for sensing and determining the position of the output gear shaft assembly. The discontinuities can be of the same or different sizes/configuration and equally or unequally spaced from each other. The discontinuities can be slots or projections or any other feature presenting a unique magnetic flux signature that can be sensed by the position sensor.Type: ApplicationFiled: September 7, 2018Publication date: March 14, 2019Applicant: CTS CorporationInventors: Max Rolf James Viebach, Kevin C.

Patent number: 9297637Abstract: A sensor assembly for sensing a movable object which, in one embodiment, includes a housing defining an interior cavity. A rotor is retained in the cavity. The rotor defines a central bore and a magnet is mounted in an off-center pocket defined by the rotor. The rotor is coupled to the shaft of the movable object whose position is to be measured. A sensor is also retained in the cavity in a relationship at least partially overlying the magnet and adapted to sense at least the direction of the magnetic field generated by the magnet to generate an electrical signal indicative of the position of the movable object. In another embodiment, the rotor and sensor are mounted in separate interior housing cavities separated by an interior housing wall.Type: GrantFiled: February 12, 2014Date of Patent: March 29, 2016Assignee: CTS CORPORATIONInventors: Kevin C. Wolschlager, Robert L. Newman, Kim D. Cook

Publication number: 20140176128Abstract: An actuator and sensor assembly comprising respective sensor and actuator housings defining an interior chamber. Clips on the sensor housing engage the actuator housing for coupling the sensor and actuator housings together. The sensor housing includes a wall defining a pocket. A connector with a sensor couples to the sensor housing in a relationship wherein the sensor extends into the sensor housing pocket. A movable piston is located in the interior chamber and a tube thereon defines a receptacle for a magnet located adjacent the pocket. The piston is seated on a flexible diaphragm. An actuator shaft includes one end coupled to the piston and an opposite end coupled to a movable object. A plurality of pins in the actuator housing mount the assembly to a support bracket. The sensor senses changes in the magnetic field in response to changes in the position of the magnet relative to the sensor.Type: ApplicationFiled: February 26, 2014Publication date: June 26, 2014Applicant: CTS CORPORATIONInventors: William D.
