ULT Motors Extend to Smaller Sizes!

Description

Applimotion’s ULT Series direct drive frameless motors are now available in sizes down to 27 mm diameter with axial length as low as 8 mm and up to a 20 mm through hole. ULT motors have been applied in hundreds of applications world wide where direct drive low profile motors enable customers to reduce system height. This new extension to smaller sizes positions ULT motors for optics applications as well as traditional direct drive rotary table systems. They are excellent for precision positioning with the use of a high resolution encoder or for continuous scanning in medical devices, computer component manufacturing or optical inspection.

ULT motors operate from traditional three phase trapezoidal or sinusoidal motor controllers ranging from 12 – 320 volts DC. Successful applications using have also been realized with sensorless motor controllers. ULT motors can achieve high speeds, up to 10,000 rpm, which is uncommon for direct drive motors and useful in some scanning applications. Hall Devices and special cable/connector options are available.

Specs

* Ultra Thin – Heights as low as 8 mm and diameters up to 165 mm * Simple Two Part Design – Frameless construction for integrating into your assembly * NdFeB Magnets – Special single ring magnetically skewed multi-pole magnets allow for concentric easy assembly. * Optional Windings – Select your voltage, speed and current, we create the winding. Also, contact the factory for complete torque speed simulation. * Sinusoidal Torque Curves – less than 1% higher harmonic content for minimum torque ripple on sinusoidal drives * Single Slot wound Stators – machine wound for more consistent performance and high reliability with no copper forming required. * 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. Recommendations on encoders also available.
