Product Description:

The ADF100D-B05TA1-AS03-A2N2 spindle motor is manufactured by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. It is intended to drive the primary spindle of machining centers, grinders, and comparable machine-tool axes, supplying the torque and speed range needed for continuous metal removal. By integrating liquid cooling and tight mechanical tolerances, the unit maintains thermal stability and positional accuracy during prolonged high-load operation in automated production cells.

With a frame that corresponds to size 100 and length code D, the motor occupies a moderate footprint while delivering the shaft power expected from a main spindle. Its rigid housing seats directly against the machine casting by means of flange mounting, eliminating alignment adapters. As a liquid-cooled asynchronous motor, coolant flows through internal channels so heat is carried away before it reaches the stator laminations. Position and speed are monitored by high-resolution motor feedback, enabling the drive to hold tight velocity tolerances during thread cutting or surface finishing. The unit is supplied without a holding brake, so external mechanical clamps must provide holding force where required. Standard rolling bearings support the rotor, and the motor comes without a shaft seal ring to reduce friction where a positive-pressure coolant environment is already present.

The rotor is trimmed to balance grade S DIN ISO 2373, which helps limit residual vibration at high speed. Power leads exit toward Side A and are routed upward because the connection housing is mounted on the top of the stator and uses a connector/plug interface. The driven end uses a plain shaft, while the opposite end has no second shaft extension to simplify integration with belt guards. Electromagnetic performance is set by winding code AS, and a standard coolant connection supports direct connection to the plant chiller circuit.
