Product Description:

The ADF134C-B05TA0-BS06-C2N2 is a main spindle motor produced by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. As a liquid-cooled asynchronous unit, it supplies continuous torque to turning, milling, and grinding centers where the spindle must follow CNC commands with stable speed control. Its integrated rotor, windings, and internal coolant passages support long machining cycles and help maintain consistent operation during heavy-duty metalworking. This operating profile suits machine tools that must hold spindle speed under changing cutting loads and repeat the same program over extended production runs.

Position feedback is provided through digital servo feedback, so the control loop receives speed and position data without requiring a separate external encoder. Because the motor is supplied without a holding brake, spindle holding at standstill must come from external clamping or drive-applied torque. Coolant flows through the stator jacket, and this liquid-cooled asynchronous motor design helps the length-code C frame remove heat during continuous operation. Installation uses flange mounting, and a plain shaft extends on Side A for direct coupling, while Side B has no second shaft end. Power conductors enter through a top-mounted housing connection, which helps keep cable routing clear of adjacent machine elements.

The rotor is balanced to S DIN ISO 2373, which helps limit vibration at the surface speeds expected from a size 134 frame. Coolant enters through an axial coolant connection with a 1/4-inch thread near the mounting face, which keeps hose routing short and away from moving tool-changing hardware. Electrical power reaches the stator through a connector plug, and the top housing orientation leaves more clearance below the spindle nose for nearby machine components. A shaft seal ring protects the standard bearing set, and the BS winding supports stable thermal behavior during extended cutting cycles.
