Product Description:

The ADF164C-B35TC0-AS06-A2V2 is a liquid-cooled asynchronous motor manufactured by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. It converts electrical energy into continuous spindle torque while permitting precise speed regulation in machining centers and other automated equipment. Its asynchronous construction works with vector-controlled inverters, and internal coolant channels extract heat to preserve output over long cycles. The motor supports cutting, grinding, and drilling tasks that demand thermal stability.

With a motor size of 164, the frame diameter supports the high radial loads of spindle heads, while the compact C length keeps the axial envelope manageable inside machine frames. As a liquid-cooled asynchronous motor, heat from the stator moves to an external coolant circuit, allowing higher continuous power than comparable air-cooled units. The housing uses flange and foot mounting, so the motor can be secured to a bed plate or directly to the machine wall. This unit is supplied without a holding brake, which removes drag torque and favors free-running deceleration when the inverter disables torque.

Dynamic control is assisted by digital servo feedback, which streams position and speed data to the drive for closed-loop regulation. The rotor is supported by heavy-duty bearings selected for high axial cutting forces, and vibration is limited to the S DIN ISO 2373 balance class to protect tool life. Power enters through a junction box mounted on the top of the housing and oriented toward Side A, simplifying cable routing inside vertical enclosures. The plain shaft arrives without a shaft seal ring, and there is no second shaft end on side B, which suits environments where external sealing is handled by the machine spindle nose. The AS winding code identifies the electrical characteristics used with compatible Indramat inverters.
