Abstract: There is disclosed herein an improved motor protection assembly for a motor compressor comprising a motor cover having an opening provided on a side wall thereof adjacent the exposed end turns of the motor stator windings. A motor protection device is adjustably secured to the motor cover and projects through the opening into engagement with a portion of the stator windings so as to enable sensing of abnormal conditions existing within these windings. The motor protection device is electrically connected to the stator windings so as to de-energize the windings in response to such abnormal sensed condition. The adjustable securing arrangement allows the axial positioning of the motor protection device within the opening to be varied thereby enabling a standard motor cover to be used with stator windings of different sizes and different manufacturers.
