Document Type and Number:
Japanese Patent JP2010063285
Kind Code:
A
Abstract:
To provide a motor equipped with a rotor with a magnet arranged in a slot of a rotor core, and a rotational angle detection means which detects the rotational angle of the rotor on the basis of a magnetic field generated from the magnet, which is configured to improve a holding force of a magnet while suppressing burrs of a sealing resin at the end of the side of a rotational angle detection means.
In the rotor 3, an area including at least the magnet 25 is sealed with the sealing resin 27 when viewing the end of the side of the rotational angle detection means from the axial direction of the rotor 3.
