maxon motor EC-I 30IE 5-wire brushless DC motor

EC-I 30IE from maxon motor is a brushless DC motor that takes a turn away from the Swiss motor company’s traditional designs. The EC-I 30IE motor features a 5-wire connection to simplify implementation and still give a wide functionality. An independent set speed value connection allows for a greater motor operating speed range over the common 2-wire approach to integrated brushless motor control. Additional features are a disable, direction and speed monitor output. It has an enclosed design that does not require any airflow through the body for cooling, which makes it suitable for harsh environments typical of the manufacturing industry.

Despite the internal motor control board, the motor has still been designed with a shaft on both ends of the body for orientation convenience and is still part of the modular construction program allowing the addition of ceramic planetary gearheads (reduction gearboxes). The motor is 30 mm diameter and 41 mm long including the control unit. It has 4-quadrant control, meaning it can control dynamic acceleration and deceleration in both directions. The controlled top speed is 6000 rpm from a 24 V supply and the 20 W power rating indicates a high power density ratio.
