Description
Because of their optimized magnetic core, the brushless EC-i motors with iron core windings offer a very high torque density and low cogging torque. The multi-pole internal rotor is extremely dynamic. Its solid design with a steel flange and housing make this motor suitable for a wide range of applications. Order your EC-i drive online now.
