Maxon’s EC-i motors are brushless, grooved internal rotor motors, featuring low inertia, minimal detent, robust bearings and compact construction. The use of high-powered permanent magnets ensures high power density, providing great speed stability under load. These motors are available in 40 mm diameter and in two lengths, namely 26 mm (50W) and 36 mm (70W). The modular system with gearheads, encoders and controllers from the maxon delivery program offers a large number of possible combinations. EC-i motors are suitable for applications such as robotics, industrial automation and security technology.
