Product Description:

The ADF132D-B05TR1-BD03-D3N1 is a main spindle motor produced by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. As a liquid-cooled asynchronous unit, it is intended to drive high-speed machine-tool spindles and other continuous-duty axes in automated lines. The combination of integral cooling, precision balancing, and encoder-based feedback allows the motor to maintain constant torque at elevated speeds, supporting repeatable machining cycles and minimizing thermal drift in demanding industrial environments. This arrangement suits applications that require stable spindle behavior during prolonged production runs.

Classified as a liquid-cooled asynchronous motor variant, the unit uses an external coolant circuit instead of forced air, enabling continuous power dissipation along motor length D. Installation is simplified by flange mounting, and its motor size 132 frame mates with standardized machine housings. Rotor balance quality is rated R DIN ISO 2373, minimizing vibration at high spindle speeds. The shaft is a shaft with a keyway, balanced with the entire key, and a shaft seal ring is fitted to protect the internal bearing set, which is supplied in a standard configuration. The power connector housing is positioned on top, keeping the cable exit clear of chip flow.

The control side is served by high-resolution motor feedback, allowing the drive to monitor rotor position precisely without additional encoders. This feedback arrangement also supports accurate response to commanded speed changes during spindle operation. For applications that rely on dynamic braking from the inverter, the motor is provided without a holding brake, eliminating residual drag during deceleration. Power is routed through a connector oriented to the right, and the plug-type interface follows the standard connector format on the top housing face. Coolant piping follows the standard connection layout, and the design includes a second shaft end on side B for coupling to auxiliary sensors or manual tachometers.
