Product Description:

The ADF160B-B05TA2-CS23-D2N1 is a liquid-cooled asynchronous motor built by Bosch Rexroth Indramat and assigned to the ADF Main Spindle Motors series. As a main spindle unit, it drives milling, turning, and grinding centers where continuous torque, thermal stability, and low vibration are required. The liquid cooling jacket removes process heat, which supports higher duty cycles than air-cooled designs and helps maintain dimensional accuracy on the machine tool. This arrangement also helps the motor hold steady operating temperature during long machining cycles.

The motor has a balance quality grade of R DIN ISO 2373, which limits residual vibration at high spindle speeds. A holding brake rated at 70 Nm secures the tool axis during tool changes or power loss. Position and speed are monitored by high-resolution motor feedback, which supplies fine incremental data to the drive controller for precise regulation. The motor uses frame size 160, and the B length code indicates a medium stack height that balances torque output with weight. The housing is prepared for flange mounting, and a standard rolling-element bearing set supports the rotor. A shaft seal ring helps keep coolant and cutting fluid away from the bearing cavity, while winding code CS matches the electrical characteristics to compatible ADF inverters.

The brake is an electrically actuated release holding brake, so the spindle remains locked when control power is absent and releases only when voltage is applied. Power cabling exits the housing on side A, and the terminal block is positioned at the top of the motor inside a sealed hood. That hood accepts a connector or plug interface, which helps simplify installation in tight enclosures and supports orderly cable routing. The output uses a shaft with keyway and is balanced with the full key to support coupling alignment. There is no second shaft end on side B, which shortens the overall spindle length and reduces load on the bearings.
