maxon DC motors 283866 with Hall sensors
EC-max 40 40 mm, brushless, 70 watt, with Hall sensor.
Description. The new maxon EC-MAX project inherits the successful concept of the A-MAX and Re-MAX motors. Electronically commutated DC motors are based on the same component platform concept, creating a wide range of market orientation in a modular system with gearboxes, sensors and brakes.
