Product Description:

The ADF132B-B05TB1-DS03-C2N1 is a liquid-cooled asynchronous motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Designed as a main spindle drive, it converts electrical energy into continuous rotary motion for machining centers, grinding machines, and other precision equipment in industrial automation. This model is delivered without a holding brake, so braking torque must be supplied by the connected drive or by external clamping devices during power-off conditions.

Rotor balance meets R DIN ISO 2373, limiting residual vibration so spindle bearings experience minimal dynamic load at rated speed. Mechanical integration is simplified by flange mounting, which lets the motor sit directly against the machine frame and keeps axial alignment accurate. Position and velocity loops benefit from the built-in high-resolution motor feedback, giving the drive controller fine electrical angle information for smooth surface finishes. Power conductors terminate on a top-mounted connector plug, allowing tool-side cable routing to remain clear. Torque is transmitted through a plain shaft, eliminating keyways that could become stress raisers in high-speed applications. The balance quality, shaft design, and standard bearings support high spindle speeds, while heat generated in the stator is removed through the liquid cooling circuit tied to the standard coolant connections.

The frame uses motor size 132 with motor length code B, giving a compact axial envelope for retrofits. Electrical characteristics correspond to winding code DS, which matches the resistance and inductance values used by the drive. Cabling exits toward side B, which keeps service access unobstructed at the work zone and aligns with the top-mounted power housing for downward drip protection. A shaft seal ring is present to block coolant ingress, and there is no secondary shaft end on the opposite face, which helps keep rotating mass lower.
