KDA 3.3-050-3-LPS-U1

Product Description

The KDA 3.3-050-3-LPS-U1 is a highly reliable, a highly precise electric drive that is used to control the rotation of the spindle motor. This top quality product is manufactured by Bosch Rexroth Indramat, renowned manufacturers of electrical parts. All of the above-mentioned parts are one single unit. This unit is an AC main spindle drive with a rated current of 50 amps and an output of 300 volts. The unit makes use of a speed serial value SERCOS interface and it also features additional input if you would like to add spindle feedback or motor feedback. The cooling system in this unit is by forced cooling by means of a cooling body fan which uses an AC supply voltage. The serial interface or the KDA 3.3-050-3-LPS-U1 is RS 232C.

Though small in size this spindle drive is quite powerful. The units are quite reliable with the ability to run for hours with many start and stop cycles. They do not fail even through multiple cycles of system run and downtime. The unit is designed to work with low vibration and minimal wobbling thanks to the magnetic heads and platters tight tolerances. Thanks to this the unit also creates a minimal amount of noise while creating low amounts of heat.

With little vibration and wobbling there is the possibility to reduce the platters track spacing – this will thereby increase the HDD data storage capacity.  The bearings that are outfitted in this spindle motors are the main reasons there is a drastic reduction in motor failures associated with this KDA drive while in use.
