Product Description:

The ADF132C-B05TB1-BS03-A2S2 is a liquid-cooled asynchronous main spindle motor produced by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. Designed for direct flange integration into machining centers and grinding equipment, the motor converts electrical energy into continuous spindle rotation while its internal coolant circuit maintains stable thermal conditions. By providing a compact, high-power drive element, it assists numerical control systems in achieving consistent cutting speeds and repeatable positioning across automated production cycles. Liquid cooling also helps reduce thermal drift during long machining runs, which supports steady spindle behavior when accuracy must be maintained over extended operating periods.

Mechanical dimensions start with the frame size of 132, and the elongated C housing increases active core length for higher torque density without changing the mounting interface. Installation relies on flange mounting, allowing axial alignment with the machine headstock. A plain shaft is supplied so torque is transmitted through a friction-fit toolholder or shrink-fit coupling. Rotor position is reported by the integrated high-resolution motor feedback, enabling the drive controller to close velocity and position loops with fine granularity. This combination supports accurate spindle alignment, secure torque transfer, and stable control behavior during speed changes and positioning tasks.

Supplementary characteristics refine operational behavior. The power connector faces on side B, simplifying cable routing toward the electrical cabinet and helping keep cable runs organized within the machine enclosure. Vibration limits are tightened by the balance grade S DIN ISO 2373, which minimizes radial runout at high speed. Because the unit is delivered without a holding brake, spindle locking during shutdown must be provided externally. Electrical parameters are identified by winding code BS, which indicates the electrical values used by a compatible inverter for spindle operation.
