Applimotion's UTS Series Slotless Direct Drive Frameless Motors are permanent magnet three phase ring type, low profile, direct drive motors with large through hole available in 29-240 mm diameters.For the ultimate in smooth operation when scanning or positioning, the UTS Series Slotless motors offer zero cogging and sinusoidal torque angle curves. Applimotion has leveraged already proven motor technology as the basis for this new family of direct drive motors. Features include wide range of diameters from 29 mm to 240 mm, low phase resistance and inductance for the motor size optimizes operation with low voltage power supplies and provides the high output with minimum voltage drop,optional windings, sinusoidal torque curves, zero cogging torque, optional back iron rings and optional hall device feedback.
