May 7, 2013 -Maxon introduces RE 30 EB 15 W DC motor for fine rotary motions.The motor is specifically designed for haptic applications 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.
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.
The 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.
