UTS Slotless Zero Cogging Motor Kits
UTS Motors
For the ultimate in smooth operation when scanning or positioning, the UTS Series Slotless motors offer zero cogging and
sinusoidal torque angle curves. Considered one of the best motor constructions for many years, Applimotion has leveraged
already proven motor technology as the basis for this new family of direct drive motors. Once you have taken advantage of a
slotless direct drive motor you won’t go back to traditional motors.
Features
Wide Range of Diameters - from 29 mm to 240 mm. Special sizes can also be created with short lead time.
Medium motor constant – 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 – Select your voltage, speed and current, Applimotion will create a special winding to optimize torque or
efficiency.
Sinusoidal Torque Curves – motor designs for optimum performance with sinusoidal current control. Less than 1% higher
harmonic content for minimum torque ripple on sinusoidal drives
Zero Cogging Torque – cogging torque has plagued many applications, motor suppliers continue to fight the
manufacturability battle to reduce cogging and keep motors consistent.
Optional Back Iron Rings - A standard set of iron rings are offered for each motor. Optional rings are available allowing
more options for higher integration.
Optional Hall Device Feedback – internally mounted PCA doesn’t add to motor height offered on some motors, others
require externally mounted hall device board.
