Product Description:

The ADF134B-B05TA0-BS06-C2H1 is a liquid-cooled asynchronous main spindle motor produced by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. In automated machining cells, the unit drives the machine spindle directly. It delivers continuous torque for milling, turning, or grinding operations while its liquid cooling keeps temperature rise in check and permits sustained high power density.

Balance quality class R DIN ISO 2373 limits residual vibration so cutting accuracy is not degraded at maximum speed. The rotor is carried by a high-speed bearing set that tolerates elevated RPM and minimizes radial runout. Heat is extracted through an axial 1/4" thread coolant inlet, allowing the motor to connect to a closed-loop chiller without additional adapters. Closed-loop control is supported by digital servo feedback, which reports precise angular position to the drive for micron-level path control. Frame size 134 indicates the stator outside diameter and correlates to the torque capability expected in heavy cutting applications. The motor is supplied without a holding brake; eliminating the brake shortens the overall length and removes drag that could otherwise affect rapid spindle acceleration.

Mechanical integration is handled through flange mounting, so the housing can bolt directly to the machine headstock. Power enters on Side A, and the housing for that connector sits on the top of the frame; the mating interface is a keyed connector/plug that supports quick service exchange. A plain shaft transmits torque to the tool interface, and a fitted shaft seal ring keeps cutting fluid out of the bearing cavity. The opposite end has no second shaft, reducing overhung mass. Motor length code B and winding code BS indicate the axial dimension and coil characteristics used with the available drive amplifier.
