Brushed coreless motor Namiki/dyNAMIX

Brushed coreless motor does not have an iron core, and consists of a cup-shaped core as rotor and a permanent magnet inside the rotor as stator.

Features:

• Cup-shaped rotor coil is very light weight and has a small moment of inertia, allowing the motor to start and stop quickly.
• Because there is no cogging due to stator-rotor positioning, it features smooth rotation, low noise and low vibration.
• Motor can be made in compact sizes because it is made only of rare earth magnet, coil and rotor.

For the reasons mentioned above, our brushed coreless motor is used in many applications that require high precision, high speed response, as well as compactness and high efficiency.

The primary factors affecting the lifespan of brushed motors are abrasion due to rotational contact of the brush and commutator, and electric corrosion during polarity switching. While precious metal contact material minimizes the electric corrosion, physical abrasion remains an issue. Changing the brush material to carbon-based can prevent the mechanical wearing, but at the same time, this can increase electric spark noise. In general, brushed motors are not suitable for power motors because they can't accept large flow of electric current.
Namiki presents brushed coreless motors that address these issues equally.
