Product Description:

The ADF132D-B05TA3-AS03-A2N1 is a liquid-cooled asynchronous spindle unit produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. This model serves as the driving element on automated machine axes where continuous, controllable rotation is required for cutting, grinding, or positioning tasks. Internal liquid circulation removes heat during extended high-speed operation, helping the motor maintain stable performance under demanding duty cycles. It is suited to machine processes that require consistent spindle behavior during long production runs.

The motor is built on size code 132 and length code D, which establish its magnetic volume and housing dimensions. Mechanical attachment to the machine frame is achieved through flange mounting, allowing direct and concentric alignment of the rotor to the driven shaft. Coolant enters and leaves through an axial rapid-action coupling interface, so the cooling lines can be connected quickly and securely. Dynamic balance is graded as R DIN ISO 2373, which helps limit residual vibration that could affect machining quality. Standard rolling bearings support the rotor, and the AS winding code matches the motor’s electrical characteristics to compatible inverters. Power conductors enter from Side A through a top-oriented housing layout that keeps the connection area clear of chip flow.

Position data are returned through high-resolution motor feedback, enabling tight speed regulation in the drive controller. The unit ships without a holding brake, so static clamping must be provided externally when power is removed. Mains cabling attaches through a connector/plug interface, which keeps the electrical connection straightforward and compact. Torque is transferred through a plain shaft that has no keyways, and the motor has no second shaft extension. No shaft-seal ring is installed, which reduces drag and supports a simple shaft arrangement.
