Product Description:

Bosch Rexroth Indramat manufactures the ADF160B-B05TA1-CS03-D2N1/S010, a main spindle motor in the ADF Main Spindle Motors series. The unit is intended for heavy-duty machining centers where a spindle-mounted induction motor is required to transmit constant cutting power. Its integrated feedback path enables the drive controller to maintain speed and torque accuracy in closed-loop industrial automation tasks. This makes it suitable for machining processes that place frequent load changes on the spindle.

At its core, the motor is a liquid-cooled asynchronous motor, so heat is removed through a regulated coolant circuit instead of ambient airflow. The housing uses size code 160, which provides a stator diameter suited to high magnetic loading without excessive mass. Rotor vibration is limited by balance grade R DIN ISO 2373, a class applied after the complete key is inserted in the shaft. Position and speed data are transferred by high-resolution motor feedback, allowing the drive to regulate spindle speed precisely during acceleration and load changes. Mechanical integration is simplified by flange mounting, which lets the frame bolt directly to the machine spindle housing. The CS winding and B length set the electrical and active core characteristics used with the matched drive package.

The electrical supply enters through a connector on side A, and the plug body is located on the top of the stator so cable runs stay clear of tooling envelopes. Because the design is without a holding brake, any static clamping force must be supplied by external actuators or drive torque. The single output side uses a shaft with a keyway, balanced with the entire key, while the rear remains sealed and has no second shaft end. A shaft seal ring is included to help contain coolant vapor and protect the bearing area. Standard bearings and coolant fittings support continuous spindle service in enclosed machine installations.
