Problems solved by technology

[0011] The first communication pattern 841 and the second communication pattern 842B are arranged in a mixed manner on the other surface side of the diverter disk 835 described above, which results in that the area of ​​the substrate (difference between the inner diameter and the outer diameter) cannot be reduced. The problem
More specifically, there is a problem that the outer diameter of the diverter disc cannot be made small or the inner diameter (the diameter of the central through hole) cannot be made large

[0062] Figure 5A is a plan view showing electrode patterns on the rear surface side of the diverter disk according to the first embodiment; Figure 5B is a plan view of the communication pattern on the front surface side of the commutator disk viewed in perspective from the rear surface side, while omitting the electrode pattern and the insulating substrate; and Figure 5C is a plan view showing the front surface side of the steering gear disc. The diverter disk 100 is formed by providing a predetermined conductive pattern made of a conductive material such as copper on both surfaces of a disk-shaped insulating substrate having an opening formed at the center thereof. The insulating substrate is formed of, for example, an insulating resin such as a glass fiber reinforced epoxy resin substrate. Details of the conductive pattern will be described later.

Abstract

The invention relates to a disk motor and an electric power tool equipped with the same. A plurality of electrode patterns constituting a plurality of commutator segments are provided on one surface of a commutator disk. A plurality of first communication patterns are provided on the other surface of the commutator disk. The respective communication patterns mutually connect first-group (odd-numbered) electrode patterns between which seven electrode patterns are sandwiched. A connection disk having the same shape as the commutator disk is provided on the commutator disk, and second communication patterns mutually connecting second-group (even-numbered) electrode patterns between which seven electrode patterns are sandwiched are provided on the connection disk.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Japanese Patent Application No. 2011-236762 filed on October 28, 2011, the contents of which are hereby incorporated by reference into this application. technical field [0003] The present invention relates to a disk motor having a commutator disk and a coil disk that rotationally drive an output shaft, and an electric drive tool assembling the same. Background technique [0004] Power driven tools include lawn mowers used to mow grass or small diameter trees and the like. In some types of electric powered tools including lawn mowers, a disc motor is used as the electric motor for rotationally driving an output shaft to which a rotary tool such as a cutting blade is attached. A disk motor has a rotor provided with a substantially disk-shaped coil disk and a commutator disk connected to a coil pattern on which the coil pattern is printed, as described in Japanese Patent No. 363670...
