Product Description:

The ADF100D-B05TA1-AS07-A2N2 is a main spindle drive built by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. In automated machining centers, the motor turns cutting tools at commanded speeds while an internal coolant jacket extracts heat from the stator iron. Operating without a holding brake leaves deceleration control to the electronic drive, which suits spindle duty where controlled speed changes are required. This arrangement supports speed-regulated machining tasks such as milling, drilling, and similar processes that rely on stable spindle rotation under changing load.

The motor uses frame size 100, and the stator stack has length D, giving a compact spindle package with the active iron needed for this build. Rotor and housing are balanced to class S DIN ISO 2373, which helps limit vibration during high-speed cutting and supports stable surface finish. Position and speed are controlled through digital servo feedback with integrated encoder, so the drive receives motor data directly without external sensors. The housing is prepared for flange mounting, which keeps the motor aligned with the spindle assembly. A plain shaft without a seal ring reduces friction losses, and the standard bearing set suits general-purpose machining.

All power conductors are routed to side A, and the connection housing sits on the top of the stator where vertical cabinet space is often easier to use. A keyed connector mates the motor leads, allowing the motor to be connected without hard-wiring at the housing. The stator jacket is flooded by process coolant, so the unit is a liquid-cooled asynchronous motor that can remove heat without external fans. Because there is no second shaft end, coupling to the tool clutch is simplified. The AS winding code matches the impedance expected by Indramat spindle inverters, and the standard coolant connection type fits common machine-tool manifolds.
