EC 25 high speed, fast and still incredibly smooth running

As an addition to the topmost performance range of EC motors, maxon motor recently launched its EC 25 High
Speed – a speed-optimized and, at the same time, small-sized 250 W drive.

EC 25 High Speed, on top of the league
Fast, and still incredibly smooth running.The EC 25 High Speed stands out with its friction-reduced and low-vibration optimized operation. Its rotor is equipped with preloaded ball bearings and a two-pole Neodymium permanent magnet. In conjunction with low loss in high speeds optimized winding, the particularly for the applications’ requirements optimized magnetic return and specially accurate dynamic balancing make the motor a real power pack in a class of its own.


Small and powerful
Dimensions of only Ø25 x 84 mm and outstanding specific values (nominal torque 42.2 mNm, nominal speed 61’600 rpm, efficiency above 93%, speed/torque gradient 44.9 rpm/mNm) make the motor particularly suitable for high speed spindle-driven applications, as required in medical technology (surgical power tools, dental drills, etc.) or machine tools (manufacture of optical lenses, fabrication of printed circuit boards, etc.).
For fast-rotating applications, a friction-reduced, low-vibration operation over the entire speed range is of vital importance. This can only be achieved with high-precision balancing and (in this case) preloaded ball bearings.
