Introduction to the Product 1-1Rexroth 1MB Frameless Spindle Motors1Introduction to the ProductRexroth 1MB liquid-cooled asynchronous frameless spindle motors areused as direct drives in motor spindles. The position of the motor betweenthe main spindle bearings gives the motor spindle a high rigidity. As aresult, the main spindle and the C axis can be operated with only onedrive in lathes, for example.1MB motors are used for turning, milling and grinding in machine tools,transfer lines, processing centers and special-purpose machines.Fig. 1.1 shows the components of an AC main spindle drive with aframeless spindle dleMotor feedbackBearingsBearingsCoolant supply linesCoolingdeviceFAKOMPAC-HSA.EPSFig. 1-1:Components of the 1MB AC main spindle drive with framelessspindle motorThe motor spindle consists of the functional units spindle with housing;bearings; frameless spindle motor with cooling; and motor feedback.The specifications of the type ofbearing priming, as well as theagainst dirt, coolant lubricants,application of the motor spindleconstructor.bearing, their lubrication, the degree ofprotection of the interior of the statorbearing grease, etc. depends on theand is the responsibility of the spindleInfluences of the frameless spindle motor functional unit on theconstruction of the motor spindle are described in this documentation.Motor feedbackThe motor feedback measures the rotor position and reports it to thecontrol device responsible for regulating the speed and position of thespindle. It is integrated in the motor spindle as an independent module.DOK-MOTOR*-1MB********-PR02-EN-PLSA Control S.L. www.lsa-control.com comercial@lsa-control.com ( 34) 960 62 43 01

The coolant fluid absorbs the power loss of the stator andthe major portion of the rotor power loss. The power loss is transferred toa superordinate coolant in the refrigeration unit.DOK-MOTOR*-1MB********-PR02-EN-PLSA Control S.L. www.lsa-control.com comercial@lsa-control.com ( 34) 960 62 43 01
