Applimotion, Inc: Direct drive slotless motors

Slotless motors provide scanning or precision positioning, and smooth motion. True sinusoidal torque curves integrate with sinusoidal motor controller electronics to create fully controllable smoothly rotating torque vector.  Motors feature an ultra-thin profile and operate from industry standard brushless DC or brushless AC drivers--from 12-300 volts--and can be wound for low or high speed applications. Motors also feature low magnetic core losses, and can operate at speeds above 10krpm. The frameless nature of these motors also allows them to be integrated into high-speed spindles where they can operate with very low heating.
