The brushless EC 25 dc motor is designed for high-speed applications up to 70,000 rpm and has low-vibration characteristic and minimized scale. Equipped with preloaded ball bearings and a two-pole neodymium permanent magnet, the motor measures at Ø25 × 84 mm, is rated for 36-Vdc nominal voltage, reaches 42.2-mNm torque, and 61,600 rpm with efficiency above 93%. The motor-specific speed/torque gradient amounts to 44.9 rpm/mNm.
The motor is suitable for high-speed spindle-driven applications, such as those used in medical technology (surgical power tools, dental drills, etc.) or machine tools (manufacture of optical lenses, fabrication of printed circuit boards, etc.).
