Product Description:

The ADF134C-B05TA0-BS06-A2N1 main spindle motor is manufactured by Bosch Rexroth Indramat as part of the ADF Main Spindle Motors series. It drives machining spindles in automated production cells where stable torque and precise speed control are required. As a spindle motor, it is suited for machine tools that must maintain smooth rotation during cutting, drilling, and similar processes. Its design supports consistent operation in equipment where speed stability directly affects surface quality and cycle performance.

Balance quality R DIN ISO 2373 keeps vibration within the tolerance needed for accurate finishing, and the standard bearings support radial and axial loads during normal spindle service. Position and speed data reach the inverter through digital servo feedback, allowing tight speed regulation at high rpm and dependable response to changing load conditions. Heat is removed through an axial 1/4-inch coolant connection, so winding temperatures remain controlled during prolonged duty. Installation is simplified by flange mounting, which allows direct attachment to the machine structure. The motor uses a plain shaft output with a smooth cylindrical journal for shrink-fit or hydraulic tool clamping, and the 134 frame diameter supports the torque level expected in mid-range machining centers.

Power enters through a connector on the top cover and is oriented on side A, helping the cable path stay clear of adjacent machine elements. The stator stack uses motor length C, which provides the axial proportions associated with this frame. The motor is supplied without a holding brake, which avoids added drag during high-speed acceleration and continuous spindle rotation. It is classified as a liquid-cooled asynchronous motor, so heat removal relies on coolant circulation rather than an external fan shroud. The housing uses the connector and plug interface specified for the series, the shaft area has no seal ring to reduce friction, and side B has no second shaft end. The BS winding code identifies conductor cross-section and resistance, and the top-entry power housing keeps access clear for tooling changes.
