Product Description:

The ADF100B-B05TA1-BS03-D2N1 is a liquid-cooled asynchronous main spindle motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. It is intended to drive machine-tool spindles in industrial automation systems. This design supports continuous torque and thermal stability during extended spindle operation. Stable temperature control helps the motor remain suited to demanding machining duty cycles.

The balance quality is rated R DIN ISO 2373, which limits residual vibration at operating speed and helps protect bearings and machined surfaces. The integrated high-resolution motor feedback supplies precise rotor position data to the drive controller, enabling accurate speed and torque control. This version is delivered without a holding brake, so any static load retention must be handled by external clamping or regenerative torque. Mechanical integration relies on flange mounting, and cabling exits toward Side A through a sealed connector housing. This arrangement supports installation in a closed spindle assembly where alignment and cable routing must remain controlled. The sealed connector housing also helps protect the cable entry area where coolant exposure is possible.

The power connector sits on the top of the housing and uses a standard plug interface so wiring stays clear of coolant manifolds. A shaft with keyway balanced with the entire key simplifies coupling to the tool interface, while a fitted shaft seal ring helps keep coolant and chips from entering the stator cavity. The motor uses size 100 with length code B, and the standard bearing set supports high radial loads common in milling or turning. Coolant ports match the standard connection type and circulate through the stator jacket for uniform heat removal. Only one drive end is present because the Side B shaft is omitted, minimizing overhang mass and leaving more clearance at the non-drive end. The BS winding code identifies the electrical configuration used by the inverter for the required current limits.
