maxon EC-i Due to an optimized magnetic circuit, the brushless DC motors with iron windings have a very high torque and very low cogging torque. The robust design with a steel flange and housing offers a wide variety of applications. The “assembled in Korea” label stands for consistently high maxon quality at a competitive price.

Dynamic, high torque, and unbeatable value.

Modular construction with gears, sensors and brakes.

The modular rotor delivers good dynamics and large torques.

The steel housing and flange ensure good heat dissipation and mechanical stability.

Shaft with no groove guarantees torsional stability and smooth running.

The stator with an iron winding is designed for high power at a low cogging torque.

"assembled in Korea": High quality due to process-monitored manufacturing on state-of-the-art assembly lines.
