Abstract
A motor assembly includes a rotor and a sensor arrangement. The sensor arrangement has a sensor and a target. The target is applied to a surface of the rotor and the sensor is mounted on a bearing shield of the motor opposite the target.
Claims20
A motor assembly, comprising:
- a rotor including a rotor shaft defining an axis;
- a bearing bracket;
- and
- a sensor arrangement having a sensor and a target,
- wherein
- the target is mounted on a surface of the rotor,
- the sensor is mounted opposite the target on the bearing bracket, and
- the bearing bracket is configured to support a bearing such that the bearing is positioned between at least a portion of the sensor assembly and the rotor in a direction orthogonal to the axis.
