Product Description:

The ADF160B-B05TB1-BS06-A2N1 is a main spindle motor manufactured by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Designed for integration with computer-controlled machining centers, the product converts three-phase electrical power into the continuous rotary motion required for milling, turning, or grinding spindles in automated metalworking equipment. Its liquid cooling circuit allows high duty cycles, while the asynchronous rotor architecture delivers the smooth torque profile needed in precision metal-cutting automation and helps support stable operation during long machining runs under continuous load. That layout suits machine tools that demand repeatable speed control and compact integration inside enclosed spindle housings.

The motor is a liquid-cooled asynchronous motor, meaning an internal coolant jacket removes heat so full nominal load can be maintained even in sealed enclosures and around machine structures that restrict free airflow. Position and velocity are relayed to the drive by digital servo feedback, letting the controller regulate spindle speed within tight tolerances during changes in cutting load and programmed speed. Machine mounting is straightforward because the housing is machined for flange mounting, which aligns the stator bore with the machine bed and supports axial preload from the work spindle. The motor has a size of 160, giving the frame enough space for the B-length active core and associated winding set, while dynamic stability is improved by a balance grade of R DIN ISO 2373 during sustained high-speed rotation.

The unit is supplied without a holding brake, so deceleration and static positioning must be handled by the inverter or external clamping devices when the spindle must remain fixed at standstill between machining steps. Power conductors are terminated through a connector plug mounted on the top of the housing and oriented on side B, keeping cables clear of the tooling area and helping routing remain unobstructed around nearby machine parts and fixed guarding. Torque reaches the spindle through a plain shaft without a seal ring, and a second shaft end is omitted to reduce overhang mass at high speed and keep the rotor assembly compact.
