Robust stator winding temperature sensor

摘要

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.
