Product Description:

The ADF160B-B05TR1-BS03-A2N1 is a main spindle motor manufactured by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. This liquid-cooled asynchronous unit acts as the rotating drive element for machine-tool spindles and similar precision equipment, converting electrical energy into regulated mechanical speed and torque for continuous machining or positioning tasks in industrial automation. In machine tools, it serves as the primary spindle drive for cutting, drilling, and positioning processes that depend on stable rotary performance. Its design supports continuous industrial duty where steady torque delivery and accurate speed response are required across changing operating loads.

For mechanical integration, the motor uses flange mounting, allowing rigid coupling to a housing bore without additional adapters. As a member of the liquid-cooled asynchronous motors family, its stator heat is carried away by an external coolant circuit, permitting high continuous power density in closed machine enclosures. The rotor has a plain shaft, so torque transfer depends on a shrink-fit or keyed toolholder rather than splines. Motion control systems rely on high-resolution motor feedback, which returns precise angular data to the drive for vector regulation and spindle orientation. The motor has a frame size of 160, which sets the overall mounting size and load capacity for production-scale machine tools.

Rotor balance meets R DIN ISO 2373, which helps reduce vibration during high-speed operation and supports bearing life. The unit is supplied without a holding brake, so spindle clamping or drive torque must hold the axis at standstill. Electrical power is supplied through a connector plug mounted on the top of the stator housing, and the cable exit is oriented to the right to simplify routing inside vertical machine columns. The winding code BS, the absence of a shaft seal ring, the standard coolant connection, and the single-ended shaft arrangement suit enclosed spindle installations that do not require an external secondary shaft end.
