Product Description:

The ADF132B-B05TA3-BS07-A2N1 main spindle motor is manufactured by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Classified as a liquid-cooled asynchronous motor, it is intended to drive machine-tool spindles in automated cutting, grinding, and milling equipment. By mounting directly to the spindle nose, it supplies torque without belts or gearboxes, and its electrical interface allows Rexroth controllers to regulate speed and position in closed-loop CNC axes. The B-length frame and 132-size stator place it in the mid-range of the series, balancing torque capability with compact dimensions for machine tools that need stable spindle response.

Balance quality meets R DIN ISO 2373, limiting residual vibration so the spindle can maintain surface finish accuracy at high speed. Process heat leaves the stator through axial cooling with a rapid-action coupling, which allows coolant lines to be disconnected quickly during service. Position and speed data are returned through digital servo feedback with an integrated encoder, giving the drive precise rotor information. Mechanical output is taken from a plain shaft, and installation uses flange mounting, which bolts the housing directly to the machine. Standard bearings support the radial and axial loads produced during heavy cutting.

The winding set uses code BS, matching the impedance required by the associated ADF inverter. Line power enters through a connector plug mounted on the housing; the connector sits on the top of the frame and the cable exits on side A, which helps routing inside compact headstocks. The unit is supplied without a holding brake, so static clamping must be provided externally when the spindle is stopped. No shaft seal ring is fitted, reducing friction losses in the liquid-cooled layout, and there is no second shaft end on side B.
