Abstract
A method for positioning a temperature sensor in association with a heat conductive surface in a lead frame located at an end of a dynamoelectric machine. The sensor is supported to the lead frame by lead wires to position the sensor at a first position spaced from an outwardly facing surface defined on the outer side of the lead frame. A cover member is moved to an attachment location in engagement with an outer side of the lead frame, wherein at least a final portion of the movement of the cover member includes positioning an engagement surface of the cover member into engagement with the sensor and causing the sensor to move closer to the outwardly facing surface to a location defining a second position for the sensor.

A method for positioning a sensor in association with an end of a dynamoelectric machine comprising a stator assembly and a rotor, the dynamoelectric machine including a lead frame at the end thereof and defining an outer side, the method comprising:
- providing a sensor supported at the end of the dynamoelectric machine by a deformable structure having a first end connected adjacent to the lead frame and a second end connected to the sensor;
- positioning the sensor at a first position spaced from an outwardly facing surface defined on the outer side of the lead frame, the first position being spaced from a second, sensing position for the sensor;
- and
- moving a cover member to an attachment location in engagement with the outer side of the lead frame, wherein at least a final portion of the movement of the cover member to engage with the outer side includes positioning an engagement surface of the cover member into engagement with the sensor and causing the sensor to move closer to the outwardly facing surface to a location defining the second, sensing position.
A method for positioning a temperature sensor in association with a heat conductive surface in a lead frame for a dynamoelectric machine comprising a stator assembly and a rotor, the method comprising:
- providing a lead frame having a temperature sensor supported thereto by a pair of wire leads extending from the temperature sensor to a connection on a portion of the lead frame;
- positioning the lead frame on the stator assembly, the lead frame including an outer side, opposite from the stator assembly, and the outer side defining a portion comprising an outwardly facing surface;
- positioning the sensor at a first position spaced from the outwardly facing surface of the lead frame, the first position being spaced from a second, sensing position for the sensor;
- and
- moving a cover member to an attachment location in engagement with the outer side of the lead frame, wherein at least a final portion of the movement of the cover member to engagement with the outer side includes positioning an engagement surface of the cover member into engagement with the sensor and causing the sensor to move closer to the outwardly facing surface to a location defining the second, sensing position.
A lead frame assembly for a dynamoelectric machine having a stator assembly and a rotor, the lead frame assembly comprising:
- a lead frame positioned on the end of the stator assembly, the lead frame including an outer side, opposite the stator assembly, defining a recess;
- a sensor supported by a pair of wire leads extending across a portion of the outer side of the lead frame, and the sensor located within the recess;
- and
- a cover member located in engagement with the outer side of the lead frame and extending across the recess, an engagement surface of the cover member located for engagement with the sensor to position the sensor at a sensing position adjacent to an outwardly facing surface defined within the recess.
