Abstract
An electric rotating machine comprises: a stator; a rotor that includes a rotary shaft, and rotates coaxially with the stator; a bracket supporting and fixing the stator, and supporting rotatably the rotary shaft; a rotational position detector disposed on the side opposite to the load of the rotary shaft to detect a rotational position of the rotor; and a power part including a switching element disposed on the outer circumferential side of the rotational position detector. A shield member is disposed at the rotational position detector to cover the circumference and shield a magnetic field generated by the switching element.
Claims8
An electric rotating machine comprising:
- a stator;
- a rotor fixed to a rotary shaft that rotates coaxially with said stator;
- a stator winding mounted on said stator;
- a rotor winding mounted on said rotor;
- a bracket that supports and fixes said stator and that supports said rotary shaft so as to be capable of rotating;
- a rotational position detector that is disposed on one end side of said rotary shaft to detect a rotational position of said rotor;
- a shield member, that covers the circumference of the rotational positional detector and that shields an external magnetic field, mounted onto said bracket;
- and
- a switching element part, that controls current to be supplied to sail stator winding or said rotor winding, disposed outside of said shield member and mounted onto said bracket;
- wherein said switching element part generates said external magnetic field.
