Product Description:

The ADF132B-B05TB1-BS03-D2N1 main spindle motor is produced by Bosch Rexroth Indramat as part of the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous motor intended for continuous-duty spindle drives in industrial machining centers and automated transfer lines. By circulating coolant through the stator jacket, the unit maintains a stable temperature profile, supporting consistent torque output and helping preserve spindle accuracy during long cutting cycles. This operating profile suits machine tools that must hold speed through changing chip loads and extended production runs.

Mechanical integration is simplified by flange mounting, which mates the motor face to the machine housing without extra brackets. The frame size 132 gives the motor its outside stator diameter, while motor length code B provides a medium rotor stack that balances torque with compact depth. Power enters through a connector plug located on the top of the stator, and the cable exits on side B so it clears the spindle nose. A standard bearing set carries axial and radial loads, and the standard coolant connection couples directly to the plant manifold. This arrangement keeps power and coolant connections accessible and leaves more clearance around adjacent tooling.

For precise speed regulation, the motor relies on high-resolution motor feedback, supplying the drive with fine rotor position data for smooth vector control. Vibration is limited by the balance class R DIN ISO 2373, which is important as the shaft accelerates toward high spindle speed. The sealing system includes a shaft seal ring and a shaft with keyway, balanced with entire key, so attached transmission components do not upset rotor balance. Because the unit is delivered without a holding brake, any stationary clamping must be handled externally. The motor uses winding code BS for electrical compatibility, retains a standard bearing arrangement, and omits a second shaft end.
