Product Description:

Bosch Rexroth Indramat builds the ADF132B-B05TB1-BS07-A2S2 as part of its ADF Main Spindle Motors series. The unit functions as a main spindle drive for machining centers and automated production cells. Within a production line, the motor couples directly to the work spindle, converting electrical energy from an inverter into torque and speed that support metal cutting, drilling, or grinding processes.

In mechanical terms, the rotor is balanced to S DIN ISO 2373, a quality grade that minimizes vibration at high spindle speeds. Axial and radial loads are absorbed by a spindle bearing, allowing continuous operation under cutting forces. The drive transmits position data through digital servo feedback with an integrated encoder, enabling closed-loop control of speed and orientation. Installation is simplified by flange mounting, so the motor face can bolt directly to the machine headstock. Cooling water reaches the stator through the standard connection on the housing, maintaining thermal stability for the liquid-cooled asynchronous motor design. The BS winding and B length class identify the electrical and dimensional layout used for this motor, so it can be paired with the intended inverter.

The spindle is supplied without a holding brake, which keeps inertia low for rapid acceleration yet requires external clamping if standstill locking is necessary. The rotor journal is a plain shaft with no keyway, and there is no shaft seal ring, so coolant leakage prevention must be handled elsewhere in the machine. A second shaft end on side B is omitted, and the power leads exit toward side B through a housing mounted on the top surface; the mating interface uses a plug-in connector. With frame size 132, the motor fits medium-power machining centers while remaining within its designated mechanical envelope.
