Product Description:

The ADF160C-B05TA3-DD07-A2N1/S043 is a liquid-cooled asynchronous main spindle motor produced by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. It serves as the electromechanical link between an inverter drive and the cutting spindle in automated machining centers, supplying continuous rotary power while its internal coolant circuit removes heat during heavy-duty cycles. By combining a closed coolant jacket with a rigid rotor design, the unit delivers the stable speed accuracy required in turning, milling, and grinding applications, and it supports repeatable spindle behavior during long production runs.

The rotor balance grade is classified as R DIN ISO 2373, which helps limit vibration so surface finish and tool life remain predictable. Position and speed data are returned through digital servo feedback with an integrated encoder, enabling the drive controller to correct deviations in real time and maintain accurate spindle response during speed changes. Installation uses flange mounting, and thermal management is supported by an axial rapid-action coupling that connects the coolant feed without threaded fittings. Power is routed to Side A, the connection exits at the top of the stator housing, and the conductors terminate in a connector plug for quick disconnection. Standard bearings support the radial and axial loads associated with high-speed spindle service, and no shaft seal ring is fitted because external pressurization is not expected on the drive end.

The motor uses a 160 frame size stator core matched to a motor length C lamination stack, giving a torque envelope appropriate for medium-power spindles without expanding the machine footprint. A plain shaft transfers torque to the spindle drivetrain, and there is no second shaft end on Side B, which simplifies coupling alignment. The unit is supplied without a holding brake, so any required static locking must be provided mechanically by the machine tool. The absence of a shaft seal reduces friction, while the top-side power box keeps connection hardware clear of coolant spray inside the enclosure.
