Motor for fine rotary motions

maxon windings and precious metal brushes generate higher torque …and many other benefits.

The centerpiece of the maxon motor is the globally patented ironless winding (on the right), System maxon: This motor concept has some very specific benefits, including low interference and no magnetic cogging. The 90% efficiency is unrivalled by other motor systems.

Haptic applications are well known in medical engineering, robotics, and aeronautics. For example: An active helicopter sidestick generates forces that provide tactile feedback to the pilot of a conventional system. Such applications require a special drive. maxon’s ironless winding and precious metal commutation were predestined for these requirements.

Special, rare and totally adapted
The new – big and powerful – RE 30 EB precious metal brushed motor is a special and rare drive, and for certain applications, it’s exactly what’s needed. Precious metal brushes are known for ensuring low, constant contact resistance over the entire service life, a characteristic that makes control far easier. This motor also features a low start-up voltage, even after a long period in standstill. With a rated torque of 53 mNm, the motor is very powerful despite the precious metal commutation, providing twice the power of an RE 25 EB. In addition, there is minimal high-frequency interference. These are all advantages that are only possible with ironless windings and precious metal brushes.

Tactile feed-back technology
The development of this motor was initialized by maxon customers. As a result, the motor is specifically designed for haptic applications (with tactile feed-back) such as surgical robots. This means the motor can also be used as a highly-sensitive sensor, acting as the sense of touch for registering mechanical resistance
