Product Description:

The ADF132D-B05TB1-AS03-B2N2 is a liquid-cooled asynchronous spindle motor manufactured by Bosch Rexroth Indramat as part of the ADF Main Spindle Motors series. Intended for high-duty cutting and grinding equipment, it delivers continuous rotary power directly to the machine spindle while an internal coolant circuit removes heat to maintain stable winding temperatures. Closed-loop control is supported so the drive can adjust torque and speed precisely during demanding industrial automation cycles.

This model is built on motor size 132 with a stator length D, giving the frame a compact profile suited to tight spindle housings. Rotor balance conforms to S DIN ISO 2373, reducing vibration at elevated speeds. Position feedback comes from a high-resolution motor feedback system that supplies fine incremental data to the drive controller. Installation uses flange mounting, and standard bearings carry axial and radial loads typical of machining operations. A standard coolant connection simplifies integration with existing liquid circuits. Electrical termination is through a connector located in a housing on top of the motor, allowing straight cable drops inside the cabinet. The power connector style matches Rexroth drive cables, and the bearing, coolant, and connection selections are standard.

The electromagnetic package uses the AS winding code, which corresponds to the resistance and current values for the intended duty cycle. Mains power is routed to side B, separating high-voltage conductors from operator access zones. Mechanical torque is transferred through a shaft with keyway that is balanced together with the full-length key, avoiding additional trim balancing after coupling. The unit is supplied without a holding brake, so static position retention must be provided by the drive or external clamps. There is no shaft seal ring, and the design omits a second shaft end.
