Product Description:

The ADF100D-B05TA1-AS03-B2N1 is a main spindle motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Designed for continuous-duty machine-tool and production-cell spindles, it supplies controlled rotary power for precision cutting, grinding, and forming operations. In these applications, the motor acts as the primary rotary drive for the spindle and supports stable speed response during cutting passes and surface-finishing steps. Consistent thermal behavior helps maintain machining accuracy during extended operation.

This unit is a liquid-cooled asynchronous motor, so stator heat is carried away by an external coolant circuit and the frame temperature remains stable under heavy load. The liquid-cooling arrangement helps limit housing temperature rise during long production cycles. Mechanical attachment relies on flange mounting, giving the machine builder a rigid face reference that aligns the shaft concentrically with the spindle housing. Rotor mass is balanced to R per DIN ISO 2373, which helps keep vibration low at high speeds. Closed-loop control is handled through integrated high-resolution motor feedback, allowing the CNC to command fine increments of speed and position. The motor is delivered without a holding brake, reducing inertial load because many spindle assemblies already use external clamping devices.

The power conductors terminate in a connector plug on Side A, and the connector housing sits on top of the stator body to keep cables clear of coolant manifolds. Top cable entry also leaves more space around adjacent coolant piping and spindle hardware. A frame designation of 100 pairs with motor length D to provide a torque range suitable for medium-capacity machining centers. The drive shaft uses a keyway shaft balanced with the entire key, enabling keyed tool couplings without upsetting the established balance grade. Standard bearings and a standard coolant inlet keep the mechanical arrangement straightforward, and the design omits a shaft-seal ring because the surrounding housing already provides positive sealing. There is no second shaft end on Side B, which shortens the overall assembly and supports compact installation in enclosed machine heads, and winding code AS indicates the electrical characteristics expected by the matching Indramat inverter.
