Non-Cogging Motor with Air Bearing Spindle Eliminates Flat Spots when Micro Grinding OD's

From ThinGap LLC
 

 
Mating a non-cogging ThinGap motor with an ultra-precision air bearing spindle enabled a micro grinder spindle/ indexing system for outside diameter (O.D.) grinding and profiling of parts with diameters as small as 25 microns. The non-cogging motor eliminated fl at spots caused by conventional brushless motor cogging, while improving accuracy, repeatability and surface finish. According to Brad Engel, president of Nelson Air Corporation, "The ThinGap motor greatly improved the roundness of the parts being ground by our customer. The motor accelerates smoothly and indexes with higher repeatability because it has zero cogging. Also, the servo is more stable, providing a better surface finish and better geometry."
Products & Services
DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors. Search by Specification | Learn more about DC Motors
DC servomotors are generally small and powerful for their size, and easy to control. Common types of DC servomotors include brushless or gear motors. Search by Specification | Learn more about DC Servomotors
Brushless motors are synchronous electric motors that have a magnetically (AC induction) or electronically (DC) controlled commutation system instead of a brush-based mechanical commutation system. Search by Specification | Learn more about Brushless Motors
