Because of their optimized magnet ring, the brushless EC-i motors with iron windings offer a very high torque density and a low cogging torque. The multi-pole internal rotor is extremely dynamic.

Its robust design, with a steel flange and steel housing, makes this motor suitable for a wide range of applications. Order your EC-i drive online now.
