Product Description:

The ADF132C-B05TB1-BS03-A2N1 is a main spindle motor in the ADF Main Spindle Motors series manufactured by Bosch Rexroth Indramat. Designed for direct integration into high-speed machining centers and automated production lines, this liquid-cooled asynchronous unit drives the spindle without intermediate transmissions, delivering consistent torque across prolonged duty cycles. Internal liquid channels remove thermal energy from the stator windings, helping the machine hold tight tolerances during continuous operation.

Its frame size is 132, giving the stator cross-section needed for continuous power. Installation to the machine headstock is simplified by flange mounting, which helps maintain axial alignment. Because the motor belongs to the liquid-cooled asynchronous motors category, its standard coolant connection attaches directly to a chiller loop, and the housing stays smaller than an air-cooled equivalent. Motion accuracy is improved by high-resolution motor feedback, letting the controller issue small angular moves for tool orientation or rigid tapping. The unit is length class C, carries a standard bearing pack, uses winding code BS to match Bosch Rexroth inverters, and has a connector and plug power interface with standard coolant fittings.

The electrical terminals exit on side B, and the molded connector housing is positioned at the top, so cables can be routed upward away from coolant hoses. A plain shaft is supplied on the drive end, while no secondary shaft is fitted on the opposite side. The rotor and complete assembly meet balance grade R DIN ISO 2373, which helps limit vibration that can degrade surface finish at elevated speeds. The motor is supplied without a holding brake, making it suitable where dynamic braking or external clamping is already present. A shaft seal ring is omitted, and the bearing system remains the standard configuration for this series.
