Title:
HIGH HEAT RADIATION MOTOR AND MANUFACTURING METHOD OF THE SAME
Document Type and Number:
Japanese Patent JP2013126287
Kind Code:
A
Abstract:
To provide a motor which efficiently emits heat generated in a coil to the exterior and makes the heat less likely to be transmitted to the control circuit and the like, and to provide a manufacturing method of the motor.
This invention relates to a motor including: a main shaft to which a permanent magnet or an electromagnet is fastened; and a resin housing where an iron core and a coil are embedded. The motor is a high heat radiation motor which includes a boron nitride powder in a resin forming the resin housing. At least a part of the boron nitride powder is oriented to the direction substantially perpendicular to the main shaft.
