1. A lead frame for a stator, comprising:
- two or more control tracks for connection to a stator winding;
a Hall-effect sensor coupled to two or more signal tracks for sensing a magnetic field and for providing electric signals to a control circuita capacitor coupled to the two or more signal tracks for dampening the electric signal provided by the Hall-effect sensor; and
a removable support for maintaining a predetermined distance between the two or more control tracks and the two or more signal tracks.

Abstract
Devices and methods are provided for a lead frame, stator, and electric motor. One embodiment for a lead frame includes two or more control tracks for connection to a stator winding. The lead frame also includes a Hall-effect sensor coupled to two or more signal tracks for sensing a magnetic field and for providing electric signals to a control circuit and a capacitor coupled to the two or more signal tracks for dampening the electric signal provided by the Hall-effect sensor. The lead frame can also include a removable support for maintaining a predetermined distance between the two or more control tracks and the two or more signal tracks.
