  • BOBBIN AND ROTATING ELECTRICAL MACHINE
    Publication number: 20150288239
    Abstract: A bobbin is mountable to a stator iron core of a rotating electrical machine, and includes a body and a protrusion. Around the body, a coil wire is to be wound. The body has an opening side end. The protrusion protrudes from the opening side end of the body in a direction approximately parallel to a coil axial direction. A terminal of the coil wire is to be wound around the protrusion.

  • Rotating electrical machine
    Patent number: 8823225
    Abstract: A motor includes: a almost annular stator, a rotor arranged inside the annular ring of the stator for rotating about a central axis, a sensor for detecting the rotation of the rotor, and a sensor board for implementing the sensor. The sensor and the sensor board are arranged outside the stator in the direction along the central axis. The sensor is a reflection type light projecting/receiving sensor.
