Product Description:

The ADF160C-B05TB2-BS13-D2V2 main spindle motor is manufactured by Bosch Rexroth Indramat and belongs to the ADF Main Spindle Motors series. It is an asynchronous drive that delivers continuous rotary power to machining spindles, positioning tables, and other precision tooling axes used throughout automated production lines. The unit’s construction supports tight speed regulation and high torque density, features that are required when a CNC must maintain dimensional accuracy during extended duty cycles in metal-cutting, grinding, and similar industrial applications.

The stopping mechanism supplies 100 Nm of static torque through an electrically actuated clamping brake, allowing the tool shaft to remain locked during holder exchange. Vibration is controlled by the balance classification S DIN ISO 2373, and the rotor is trimmed with the complete key to preserve that grade at operating speed. Inside, heavy-duty bearings absorb combined radial and axial forces produced during aggressive cuts. Installation is direct because flange mounting aligns the housing with the machine frame. Motion data are returned through a high-resolution motor feedback interface, enabling the drive to close fast velocity loops. A shaft seal ring blocks coolant entry, and omitting a second shaft end prevents overhang that could magnify dynamic deflection.

The motor uses liquid cooling, with coolant circulating through internal channels to remove heat so the frame size 160 can sustain high continuous output during demanding spindle duty. The length designation C extends the active iron stack while keeping the overall diameter unchanged, which increases the available magnetic length without enlarging the motor’s outer profile. Power conductors enter on side B through a detachable connector/plug that sits in a molded housing on top of the stator, simplifying vertical cable runs. Electrical characteristics correspond to winding code BS, supporting optimum current density without exceeding thermal limits.
