Motor Types, Brush Materials and Sizes

Home > Technical Guide > Classification of Motors > Motor Types, Brush Materials and Sizes

This content shows the types of our motors. Our motor type code is based on the classification shown in this content.

Motor-housing Shape

Our motors are classified into three types by the motor-housing shapes.

Flat type
Round type
Square type

Size indication of each type is as shown right.

Motor-housing Shape

Brush Materials

Brush is classified by the materials of the portion that has slide-contact with a commutator.

Metal Brush

The brush that integrates with a terminal easily and used mostly for our economical models. Also named sheet brush.

Precious Metal Brush

The brush for which special precious metal is employed at the slide-contact portion with the commutator, and mainly used for our motors with low current and low output under low voltage. Also named a fork brush by its shape.

Carbon Brush

The brush for which a carbon is employed at the slide-contact portion with the commutator and fixed to a elastic brush-arm to have electrical conduction, and mainly used for our motors with high current and high output under high voltage.
