Product Description:

The ADF160C-B05TA1-BS07-D2N1 is a liquid-cooled asynchronous motor manufactured by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. Designed as a main spindle drive, it converts electrical energy into constant rotary motion for machine tools and automated production cells where prolonged duty cycles and tight dimensional tolerances are required. Liquid cooling carries heat away from the windings so the motor can support sustained spindle operation. It is intended for spindle duties that require stable rotation during long machining cycles.

The motor has a motor size 160 frame and a corresponding motor length C, giving the rotor the mass needed for stable speed regulation. The unit uses flange mounting, so axial alignment to the machine housing is maintained without additional brackets. Position data are supplied through digital servo feedback with an integrated encoder, allowing the drive controller to synchronize spindle speed with machining commands. Dynamic repeatability is aided by balance grade R per DIN ISO 2373, which limits residual vibration at rated speed. A standard bearing set supports the shaft, and the BS winding code matches the stator impedance to compatible Indramat inverters during continuous operation.

Power leads enter on Side A through a top-mounted housing that accepts a connector plug, which helps simplify cable routing inside crowded spindle heads. Torque is transferred by a shaft with a keyway that is balanced with its full key, while a shaft sealing ring helps keep coolant mist from migrating along the journal. There is no second shaft end on Side B, so encoder and coolant hardware share the non-drive end of the motor. Because the motor does not include a holding brake, spindle arrest must be handled by an external clamping system when power is removed.
