Product Description:

The ADF132B-B05TA1-DS06-H2N1 main spindle motor is produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous unit. It drives machine-tool spindles and other continuous-duty axes that require stable torque and controlled thermal conditions in industrial automation.

Balance quality is graded to R DIN ISO 2373, limiting residual vibration transmitted to tooling. The rotor position is monitored through digital servo feedback, allowing the associated drive to close velocity and position loops without an external encoder. With a frame that follows motor size 132, the stator dimensions match medium-power machining centers. Mechanical attachment is via flange mounting, so the housing bolts directly to the machine headstock. Electrical power is delivered through a plug-in connector, and the connection housing sits on the top of the unit while the cable exits toward Side A to simplify routing inside the cabinet. The motor uses standard rolling bearings, and the coolant passes through a standard connection to remove heat from the stator jacket. A shaft with a keyway balanced with a half key is included, and a shaft-seal ring blocks coolant or lubricant from entering the bearing chamber.

The motor is supplied without a holding brake, so static load-holding must be provided by the machine mechanics or by drive torque alone. Length code B indicates a medium active core length that balances output power with overall mass, while the absence of a second shaft end keeps overhang loads on the non-drive side to a minimum. Wiring orientation is fixed toward Side A, aiding repeatable installation across identical machines. The electromagnetic package follows winding code DS, enabling the drive controller to apply optimized current limits and parameter sets for this coil style.
