Product Description:

The ADF160B-B05TA1-CS03-D2N1 is a main spindle motor built by Bosch Rexroth Indramat and supplied within the ADF Main Spindle Motors series. As a liquid-cooled asynchronous motor, it provides continuous torque for machine-tool spindles where thermal stability and high speed are required. The unit’s integrated construction, flange interface, and feedback provisions allow it to connect directly to Indramat drive controllers and maintain closed-loop speed control in demanding automation axes.

The motor uses size class 160 with length code B, giving a stator stack that supports power without enlarging footprint. Its endshield is machined for flange mounting, so axial alignment to the machine frame is set by the pilot diameter rather than foot bolts. The rotor balance grade is R DIN ISO 2373, reducing vibration when the keyed shaft, balanced with the entire key, spins at operating speed. Internal lubrication relies on a standard bearing set that supports the radial loads typical of spindle designs. Temperature is managed by liquid passages surrounding the stator, and a standard coolant connection simplifies hose routing. For position and speed loops, the unit employs high-resolution motor feedback, and it is delivered without a holding brake, a configuration common for continuous rotating spindles where mechanical locking is unnecessary. The electromagnetic characteristics are identified by winding code CS.

Electrical cabling is attached through a connector. It is oriented toward Side A, and the housing for this interface sits on the top of the motor, allowing vertical drop-loops that clear adjacent tooling. A factory-installed shaft seal ring protects the front bearing from coolant ingress, while the absence of a second shaft end on side B minimizes overall length and removes the need for rear guarding. The coolant circuit, bearing arrangement, and CS winding selection support sustained high-speed duty in automated machining centers.
