Abstract:

An arrangement for measuring the operating temperature of an electromechanical machine utilizes at least one elongate sensor device inserted into a winding slot of the stator core. The sensor device includes a lead attachment portion at which a plurality of relatively large gauge lead wires are attached. The lead wires preferably have a length sufficient to extend to a location outside of the motor housing. The sensor device includes an elongate sensing portion having temperature sensitive conductors. Preferably, the sensing portion is located entirely within the axial extent of the stator core. An elongate transition portion having temperature insensitive conductors provides electrical connection between the lead wires and the temperature sensitive conductors of the sensing portion.
