Disclosed herein, among other things, is a stator winding temperature sensor. According to an embodiment, the sensor includes at least one sensing wire coil adapted to be connected to a stator. The sensor also includes a body, including a core material surrounding at least a portion of the sensing wire coil, and a laminate material over the core material. The body has a thickness adapted to protect the sensing wire coil. The sensor includes a lead wire adapted to connect to an external monitoring device. The sensing wire coil is electrically connected to the lead wire at a lead step portion of the sensor. In addition, the sensor includes a tab extending from the lead wire and encompassing the lead step. The tab protects the lead step and the sensing wire coil in a region where the sensor extends over an end of the stator.

Robust stator winding temperature sensor

A stator winding temperature sensor including at least one sensing wire for connecting to a stator. The sensor also includes a body, including a core material comprising a polyimide substrate having an acrylic adhesive surrounding at least a portion of the sensing wire, and a laminate material over the core material. The body has a thickness adapted to protect the sensing wire. The sensor includes a lead wire for connecting to an external monitoring device. The sensing wire is electrically connected to the lead wire at a lead step portion of the sensor. The sensor further includes a tab extending from the lead wire and encompassing the lead step, the tab including a flexible zone where the tab is surrounded by a polyimide and an adhesive but is not surrounded by fiberglass.

Reinforced flexible temperature sensor

One example of the present subject matter includes a first elongate section having a first flexible conductor enveloped by a first jacket; a second elongate section having a second flexible conductor enveloped by a second jacket; and an sensor section having an elongate flexible tubular shape, the sensor section housing a resistance temperature detector element which is at least partially coiled and which is resistance welded to the first flexible conductor at a first weld and to the second flexible conductor at a second weld; wherein the sensor section at least partially envelops and overlaps the first elongate section and the second elongate section, with a first band crimping the sensor section to the first elongate section, and a second band crimping the sensor section to the second elongate section, and with the first and second welds disposed between the first and second bands.
