Product Description:

The ADF160C-B05TA3-DD07-A2N1/S011 main spindle motor is built by Bosch Rexroth Indramat and belongs to the ADF Main Spindle Motors series. As a liquid-cooled drive for machining centers and other automated machine tools, it turns the cutting spindle directly and delivers constant torque during prolonged duty cycles. Because it is an asynchronous design, no permanent-magnet detent torque is present, which helps support stable operation when precise surface finish and dimensional accuracy are required.

This model is classified as a liquid-cooled asynchronous motor, so the stator jacket carries coolant to remove losses instead of relying on ambient air. Its frame corresponds to motor size 160, and the active stack uses length code C, so the mounting dimensions match large vertical or horizontal machining spindles. Rotor vibration is limited to R DIN ISO 2373 balance quality, which helps reduce runout at high speed. Standard rolling bearings support radial cutting forces, and the machine bed receives the unit through flange mounting. Electrical power enters from the top of the housing on Side A through a connector/plug interface, and coolant enters axially through a rapid-action coupling.

Position and speed are supervised by a digital servo feedback system with an integrated encoder, allowing the controller to synchronize spindle speed with toolpath commands. The drive shaft is a plain shaft without keyways, which permits shrink-fit tool clamping and helps minimize imbalance. For applications that use external clamping devices, the motor is supplied without a holding brake, and there is also no shaft seal ring, so the installation must provide its own contamination barrier. The rear of the rotor has no second shaft end, which helps keep the enclosure layout simple and the overall length compact.
