The BMN07-12XX is a brushless, sensorless micromotor from Orbray, developed for applications that require compact design, low weight and high performance. With a diameter of 7 mm and a length of 12 mm, this motor offers powerful operation in a very small format. It is equipped with sleeve bearings and is designed to be combined with planetary gears to achieve the desired gear ratio and torque.<\/p>\n
The motor is available in 3.0 V and 5.0 V versions, with a no-load speed of over 21,000 rpm. It has a stall torque of 0.30 mNm and an output power of 0.2 W, with an efficiency of up to 22%. The terminal resistance varies depending on the model, contributing to different performance profiles. With low friction, fast mechanical response time and low rotor inertia, the BMN07-12XX provides smooth and responsive operation, even with very small movements.<\/p>\n
The motor is built to withstand temperatures from -20 to 80 \u00b0C and has a maximum winding temperature of 90 \u00b0C. It weighs only 3.8 grams and can handle radial shaft loads up to 0.27 N and axial loads up to 4.9 N in a stationary position. A sensored version is available as an option for applications requiring precise position control.<\/p>\n
The BMN07-12XX is particularly suitable for medical technology, precision mechanics, microrobotics and other high-precision systems where size, power and reliability are crucial.<\/p>","protected":false},"excerpt":{"rendered":"
