Product Description:

The ADF164B-B35TC0-AS06-A2N1 is a main spindle motor from Bosch Rexroth Indramat's ADF Main Spindle Motors series. Designed for machine tools and other automated equipment, it converts regulated drive power into high-precision rotation for milling, turning, and grinding spindles. An internal coolant jacket keeps the copper and stator laminations within their thermal limits, supporting continuous duty without performance drift. The model interfaces with Indramat drive controllers through an encoder link, making it a central actuator within closed-loop CNC systems.

The rotor and stator are balanced to R DIN ISO 2373, limiting residual vibration that can degrade surface finish at high speeds. Position information is supplied by digital servo feedback, allowing the control to synchronize spindle angle with tool paths. Frame designation 164 indicates the outer diameter and standard bearing spacing. The housing supports flange and foot mounting, so the unit can be secured to a headstock plate or directly to base rails. Incoming power is terminated in a top-mounted junction box, giving access for armored cable glands while keeping conductors away from coolant spray. The AS winding code matches the electrical characteristics expected by Rexroth frequency converters, and the bearing type is the standard deep-groove configuration.

The motor is delivered without a holding brake, so stopping must be handled by the drive or an external clamp. Power conductors exit on side A, simplifying cable routing when the opposite end is inaccessible. As a liquid-cooled asynchronous motor, it removes heat through the coolant channel even though the housing uses the compact motor length B version. A plain shaft with no keyway is provided on the drive end, and there is no second shaft end on side B. The housing lacks a shaft seal ring, which reduces friction, and the power connection housing sits on top of the frame.
