Product Description:

The ADF160C-B05TB1-BS06-D2V1 is a main spindle motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. This liquid-cooled asynchronous unit is intended to drive machining spindles, grinders, and other continuous-duty axes in automated equipment, delivering constant torque while its internal coolant circuit removes process heat. Within an automation cell, it interfaces with an Indramat drive controller to provide regulated speed and torque.

Its rotor is dynamically balanced to R DIN ISO 2373, which helps reduce vibration that can affect surface finish. The shaft runs on heavy-duty bearings selected to support radial loads generated during high-speed cutting. Position data return is handled by digital servo feedback, which sends speed and angle information to the drive for closed-loop control. Mechanical integration is simplified by flange mounting, because the motor face seats directly against the machine frame without requiring adapter plates. Electrical power is fed through a sealed connector plug that helps keep coolant mist away from live conductors.

The three-phase supply enters on side B of the frame, and the power connector is located on the top to help cables clear coolant ducts. The motor uses frame code 160, which corresponds to the stator diameter, while winding code BS identifies the thermal and electrical constants used for liquid cooling. The C motor length provides intermediate continuous power without extending the installation envelope. Because the unit is supplied without a holding brake, axial locking must be provided by the drive when the machine stops. The shaft has a keyway and an integral sealing ring to help limit coolant ingress, and the back face has no second shaft end machined into it. A standard coolant connection is also included.
