Product Description:

The ADF134C-B05TA0-BS07-C2N1/S032 is a liquid-cooled asynchronous main-spindle motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. As a spindle drive, the unit delivers continuous rotary power to machining centers and other automated production equipment where precise speed control and high thermal stability are required. It is a liquid-cooled asynchronous motor, so induction operation is supported without external fans.

The motor has size 134 and length code C, giving fixed reference points for selecting compatible housings and couplings. A flange mounting interface centers the stator on the machine frame, while a plain shaft transmits torque without keyways to minimize imbalance. Dynamic balance is rated at R DIN ISO 2373, so residual vibration stays within grade R for high-speed spindle service. Internal bearings use the standard design class to support radial and axial loads during cutting cycles. Liquid enters through an axial connection with a 1/4-inch thread fitting that directs coolant along the stator jacket to maintain temperature during continuous high-power operation. Power conductors enter through a connector plug, which simplifies motor exchange and helps seal the winding chamber against coolant mist.

An integrated encoder supplies position data via digital servo feedback with an integrated encoder, enabling closed-loop spindle speed regulation by the drive controller. The unit ships without a holding brake, so axis lockdown during power loss must be handled by the machine tool's mechanical clamping system. Electrical routing stays orderly because the power connector faces Side A and is located on top of the housing, which helps prevent cable interference with chip guards. A shaft seal ring is present to block coolant ingress, and the motor is built without a second shaft end to reduce overall length on Side B. Winding code BS matches the motor's impedance to ADF-series frequency inverters for stable current draw at rated speed.
