Danaher Motion Introduces New Dover Single Axis Controller and Air Bearing Spindle Product Set

Perfectly matched technology delivers maximum velocity stability for faster testing in HDD applications

WOOD DALE, IL - Danaher Motion introduces the Dover DMM-101 Single Axis Controller and ST1 Air Bearing Spindle product set. The DMM-101 and ST1 are engineered to form a perfectly matched and easily integrated sub-system solution for hard disk drive (HDD) applications, but can also be sold separately.

"Dover products are renowned for their cutting edge motion performance and reliability, and the DMM-101 and ST1 product set, consisting of a controller, spindle, software and cable, takes that one step further. To help OEMs build an even better data storage solution, this fully integrated system eliminates the need for users to specify separate components, and then try to figure out how to piece them together to maximize performance," says Mark Wilson, Data Storage Segment Manager, Danaher Motion-Dover.

The DMM-101 single axis controller delivers unmatched velocity stability performance (0.0006% at 7200 RPM) to provide a stable test platform for increased aereal track densities. Its flexible connector interface accepts both MCS-LA2000 and MFM-BDC-610 connections, making it well suited as a drop-in replacement in today's media testers. User adjustable PID gain adjustments optimize performance with any payload.

Additionally, the DMM-101 can position the spindle to any encoder count within one revolution relative to the index, while enabling users to simplify commutation by eliminating the need to align the encoder index to a motor pole.

The ST1 air bearing spindle provides low asynchronous error motion (AEM) performance, less than 1.5 nanometers (1 sigma) up to 20,000 rpm. The ST1 also delivers acceleration of less than 1 second to 15,000 RPM for 65 mm disks, with an up to 33% reduction in rotor inertia over competitive products, allowing users to benefit from improved throughput and faster testing of media. A crash resistant coating promises durability and robust operation.
