Synchronous rotary electrical machine for on-board traction application of electric motor vehicle, has measuring sensor including sensitive head that is mounted nearer to junction of non-isolated conductive ends at common star point

摘要

The machine has a stator including a magnetic circuit pierced axially in a cylindrical channel between axial terminal faces. The stator has a physical parameter measuring sensor i.e. positive temperature coefficient probe (125), that measures a physical parameter in the machine. The sensor is connected to an exterior of the machine by a data transmission line (126). The sensor has a sensitive head that is sensitive to the physical parameter. The sensitive head is mounted nearer to a junction of non-isolated conductive ends (200-2, 200-4, 200-6) at a common star point.
