Brushless DC motor - EC 25 High Speed
Fast DC motor, and still incredibly smooth running.
Brushless DC Motors. As an addition to the topmost performance range of brushless DC motors, maxon motor launches its EC 25 High Speed – a speed-optimized and, at the same time, small-sized 250 W DC motor.
Fast, and still incredibly smooth running. Or, in other words: EC 25 High Speed.
The EC 25 High Speed brushless DC motor stands out with its friction-reduced and low-vibration optimized operation. Its rotor is equipped with preloaded ball bearings and a two-pole Neodymium (rare earth) 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 motor balancing make the motor a real power pack in a class of its own.
Dimensions of only Ø25 x 84 mm and outstanding specific values (nominal torque 42.2 mNm, nominal motor speed 61 600 rpm, efficiency above 93%, speed/torque gradient 44.9 rpm/mNm) make the brushless DC 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.
maxon motor also manufacture custom gear box, gear head and feedback systems.
