ATOM EC Series

The benefits of this new technology are torque and high speed when compared to the same sizing. The lack of cogging, a reduced ripple torque, a linear correlation between speed and torque, and low inertia bring performance to a greater level in terms of power, and dynamics through reduced weights and dimensions.
Servotecnica’s brushless motors apply hall sensors as a standard option and have the magnetic encoder option. Thanks to the sensors, it is possible to control rotation speed and, thanks to the lack of cogging, provide high performance and accuracy.
