Product Description:

The ADF164B-B35TC0-AS06-A2N2 is a liquid-cooled asynchronous main spindle motor manufactured by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Intended for continuous service in machining centers and forming lines, the unit turns electrical energy into stable rotary output while its internal coolant jacket removes heat independently of surrounding air. This arrangement lets the motor sustain rated torque inside sealed machine guards where fan-based cooling is impractical and ambient temperatures can rise during heavy production cycles.

Balance accuracy is classified under S DIN ISO 2373, limiting residual vibration at rated speed and protecting bearings. The integrated digital servo feedback returns absolute rotor position to the drive controller, enabling tight speed and torque regulation. Because the motor is supplied without a holding brake, external clamping or drive torque must secure vertical axes when power is removed. With frame size 164, the motor has a larger stator cross-section, giving higher continuous output without increasing shaft height. Mechanical attachment uses flange and foot mounting, so the housing can be fixed to a base plate or a machine face without adapters. Standard bearings and the B-length stack complete the mechanical layout.

Electrical terminations are routed to side A, and the connection hardware is housed in a top-mounted junction box, keeping cable bends short when the motor sits low inside a cabinet. A plain shaft is supplied, eliminating keyways that might create stress risers, and torque transfer occurs through shrink discs or friction couplings. Windings identified by AS align with drive modules that supply the required frequency and current for this cooling concept. The omission of a shaft seal ring cuts drag losses, and the rotor keeps the overall length compact for tight spindle spaces.
