ATOM SC Series
The benefits of this building technology combine the simplicity 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 keeps the motor diameter unvaried with a slight increase in length.
Technical Specifications
- From 12 to 36mm diameter
- Integreted speed control
Attributes
Customizable
High efficiency
Integrated drive
Low inertia
Low noise
