Product Description:

The ADF134D-B05TC0-BS07-A2N1 is a liquid-cooled asynchronous motor built by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. As a main-spindle drive, it converts electrical energy into continuous rotary motion for milling, drilling, and turning centers that require stable speed under high thermal loads. Its liquid-cooling layout supports sustained spindle duty in enclosed machine spaces where heat buildup can reduce accuracy and limit continuous output in air-cooled designs.

The rotor is balanced to R DIN ISO 2373, reducing residual vibration that could mark finished surfaces. Frame dimensions follow motor size 134, giving a large stator bore for high torque, while length code D extends the active core to increase power density. Coolant enters through an axial port with a 1/4″ threaded fitting, so liquid removes heat directly from the housing and allows full output even inside closed machine enclosures. Position data comes from digital servo feedback embedded in the motor, enabling the drive controller to hold commanded speed within tight tolerances and detect overspeed within one electrical cycle. Bearings are the standard precision type, and the balance quality works with them to limit runout at high speeds. Winding code BS indicates slot fill and impedance so the motor matches ADF-rated inverters without additional tuning.

This model is supplied without a holding brake, making it suitable for spindle applications where clamping devices secure the shaft during tool changes. Electrical power reaches the stator through a sealed junction box that sits on the top of the frame, and the conduit turns toward Side A for straightforward cabinet routing. Torque is delivered through a plain shaft, and the lack of a keyway helps minimize imbalance at very high speeds. A flange mounting face centers the housing against the machine headstock, a shaft-seal ring is omitted because positive coolant pressure prevents ingress, and the opposite Side B end is closed so there is no second shaft extension.
