Title:

SMALL-SIZED CORELESS MOTOR AND RADIO CONTROL TYPE MODEL GAME MACHINE

Document Type and Number:

Japanese Patent JP2005192280

Kind Code:

A

Abstract:

To constitute a small-sized coreless motor which is light as the entire rotor, low in inertia, small in mechanical time constant, quick in response, and is excellent in reliability and durability by elevating heat dissipative property, and a radio-guided model game machine which is excellent in servo performance, reliability, and durability.

The small-sized coreless motor is constituted, including a cup-type rotor which is composed of a coil 1 that is wound in cylindrical form out of a copper-clad aluminum wire or an aluminum wire, a hub 2 that is made in disc form out of aluminum or aluminum alloy, and a rotating shaft 3 that is retained by an commutator base 10 of insulating resin provided at the center of the hub 2. It is mounted as a servo motor on a radio-guided model game machine.
