Product Description:

The ADF184D-B35TC0-DS06-A2N2 is a liquid-cooled asynchronous main-spindle motor manufactured by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. In machine tools and other automated equipment, this motor supplies the continuous speed and torque required to cut, mill, or grind without external gearboxes, improving dynamic response and thermal stability within compact envelopes. Installation flexibility is provided by flange and foot mounting, allowing either face or base attachment to the machine bed.

The motor has a frame size of 184 and a length code of D, giving the stator and rotor the volume needed for high power density. Rotor balance is graded to S DIN ISO 2373, limiting residual vibration and protecting spindle bearings during high-speed operation. Internal liquid cooling leaves the housing smooth because coolant is introduced through an axial connection with a 1/2-inch thread, simplifying hose routing. The DS winding set achieves the required flux while keeping copper losses low. Standard rolling bearings support the shaft, and there is no shaft seal ring, so the coolant circuit must remain isolated from the drive end. Power enters on side A through a top-mounted junction enclosure, and the conductors exit the machine cabinet toward the drive inverter.

Position feedback is supplied by digital servo feedback, which sends high-resolution speed data to the CNC controller. Main conductors terminate in a junction box on the housing, keeping signal and power wiring segregated. The unit is delivered without a holding brake, so axial restraint must come from the drive or an external clamp when power is removed. A plain shaft design simplifies coupling to precision tool holders. There is no second shaft end on side B, which reduces overall length and eliminates unused overhang.
