Maxon Precision Motors' new "RE" series of motors use powerful rare-earth magnets and graphite brushes to eke out the highest torque possible in a 25-mm diameter package, Maxon says.

The ironless rotor allows for zero cogging and simple, accurate control. Weighing 4.6 oz and measuring 2.1 inches long, the 25 mm motor is rated at 20W. Maximum speed is 11,000 rpm, and maximum efficiency is 87%. Maxon Precision Motors, Product Code 4216.
