Product Description:

The ADF132B-B05TB1-BS06-A2S2 is a liquid-cooled asynchronous motor manufactured by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. As a main spindle drive, it converts electrical power into the torque and speed required by CNC machining centers and other automated equipment, operating under closed-loop control from the accompanying drive electronics. A liquid circuit removes stator heat through standard coolant fittings, allowing continuous duty at elevated spindle speeds. This cooling method helps the motor maintain stable thermal behavior during long machining cycles and repeated changes in spindle speed.

With a frame size of 132 and the B length code, the motor offers a mid-range active core suited to medium-power spindles. It bolts directly to the machine column through flange mounting, and a spindle bearing set carries axial and radial loads during cutting. Position and speed feedback is supplied by digital servo feedback, allowing the controller to adjust current in real time. This feedback arrangement supports quick correction of load changes during machining. Rotor balance meets S DIN ISO 2373 to limit vibration at high speed, while winding characteristics follow the BS code so the drive uses the appropriate parameter set. The design omits a shaft seal ring to reduce friction losses.

Electrical energy is delivered through a connector plug interface on side B, and the top-mounted power housing helps shorten cable runs inside vertical heads. This arrangement keeps the connection area accessible when the motor is installed in compact spindle assemblies. Because the unit is supplied without a holding brake, any static locking torque must be provided by the drive or by external devices. Drive torque is transmitted through a plain shaft, and there is no second shaft end on the rear, which simplifies pulley or chuck attachment.
