Product Description:

The ADF134B-B05TA0-BS07-A2N1/S032 is a liquid-cooled asynchronous main spindle motor from Bosch Rexroth Indramat in the ADF Main Spindle Motors series. It serves as the primary drive element for machine-tool spindles, delivering continuous rotary motion under inverter control. A flange mounting interface secures the housing to the machine bed, and a plain shaft transmits torque directly to the spindle train. The design omits a shaft sealing ring and a secondary shaft end to simplify mechanical integration.

For smooth high-speed operation, the rotor is balanced to class R per DIN ISO 2373, which limits vibration that could degrade surface finish or shorten bearing life. Heat generated in the stator is removed by liquid flowing through an internal jacket; the circuit is fed through an axial coolant connection with a 1/4-inch thread that mates with standard quick-fit couplings. Position and speed are monitored by a digital servo feedback system that combines an encoder with real-time data transmission to the drive, enabling dynamic spindle control. Electrical power reaches the windings through a screened connector plug, and the housing is positioned on top of the stator to keep cabling clear of chip discharge systems. Standard rolling bearings support the rotor and accommodate radial cutting forces.

Dimensional parameters follow the ADF coding scheme: the frame is classified as motor size 134 and the active core depth is identified by motor length B. Supply conductors exit the enclosure on side A, matching cabinet layouts that route energy chains from the front of the spindle head. Because the motor is supplied without a holding brake, spindle clamping must be handled by an external drawbar or hydraulic chuck. Electrical characteristics correspond to winding code BS, allowing the drive to match rated voltage and current without derating.
