Product Description:

The ADF100D-B05TA1-AS03-C2N2/S017 is a main spindle motor manufactured by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. As a liquid-cooled asynchronous unit, it delivers continuous rotary power to machining centers and other automated equipment that demand high duty cycles. Installed in machine-tool spindle assemblies, the motor converts electrical energy into controlled torque and speed for cutting, drilling, and grinding across industrial production lines. This layout supports steady operation during long machining runs where thermal stability and repeatable speed control are important. It is suited to applications that alternate between roughing and finishing passes without frequent stops.

Its size rating of 100 sets the stator diameter so the housing aligns with existing machine frames. The motor uses flange mounting, so it attaches directly to the spindle housing without separate feet. Power enters through a connector on Side A at the top of the housing, which helps keep cable routing clear of the rotating output area. Balance class S DIN ISO 2373 limits residual vibration during high-speed cutting. Standard bearings, a basic coolant inlet, and motor length D support continuous liquid circulation around the stator. A shaft-seal ring protects the single output end from coolant ingress, and the motor is supplied without a holding brake to keep rotating mass low. The connector and plug interface keeps the electrical connection compact and enclosed.

The motor uses high-resolution motor feedback to provide precise rotor position data, which helps the drive maintain stable speed control during tapping and contour milling. A plain shaft allows direct coupling to tool-side components without adding keyway geometry. The design omits a second shaft end, leaving more space on Side B for encoder components or coolant unions and reducing rear-end packaging conflicts in compact spindle assemblies. This arrangement also preserves access around the non-drive end where surrounding spindle hardware can be tightly packed. Electrical behavior follows winding code AS, which matches the current and voltage characteristics expected by compatible ADF inverters. Bearing type, coolant connection, and the power connector remain in the standard configuration.
