The new EC16 motor developed by maxon is a brushless DC motor. An out-standing characteristic is its power density. At only 16 mm in diameter and a length of 56 mm this brushless DC motor brings a power rating of 40 Watt! The reasons for this improvement can be found, on one hand, in the optimised winding technology – the consequence is less eddy current losses. On the other hand the active parts, for example the magnet and winding, take up a relatively large volume of the motor. Another advantage is the high surface to volume relationship. The heat energy produced in the brushless DC motor can be distributed more efficiently.

The speed range of this fast running motor is from 0 to 60,000 rpm. Lower speeds and a corresponding high torque can be implemented with a planetary gear from the maxon modular system. Brushless DC motors need the information of the actual rotor position for the electronic commutation of the three phases. With the available motor, the proven concept to separate the control magnet from the main magnet has been applied.

Thus the Hall sensors of the electronic commutation are protected against interference of the magnet and the winding current. The significant characteristics of this brushless DC motor with the best magnet material available on the market today, Neodymium, are the small dimensions, the extremely wide speed range, the high dynamics and specifically the unsurpassed lifespan.

Further advantages are high efficiency, no cogging, and the largely linear speed/torque gradient which enables excellent control characteristics. These servo-drives are mainly used in medical and dental technology, as well as in high speed construction tools and automation systems.
