2 Pole Coreless Brushless Micromotors with I.E.

ATOM SC Series

The benefits of this building technology join the simplicity of use of a brushed DC motor with the longevity of a brushless motor, maintaining cost-effectiveness and ease of integration.
The lack of cogging is typical of coreless motors and guarantees a reduced ripple torque, a linear correlation between torque, speed, and low inertia.
The miniaturization of the electronics allows us to maintain the diameter of the motor unvaried with a slight increase in length.

Technical Specifications

  • From 12 to 36mm diameter
  • Integreted speed control

Attributes

Coreless
Customizable
High efficiency
Integrated drive
Low inertia
Low noise
