Product Description:

The ADF104C-B05TA1-AS07-A2N1 is a liquid-cooled main spindle motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Designed for continuous duty in CNC machining centers and automated transfer lines, the motor forms the core of a spindle assembly, delivering controlled speed and torque to the cutting tool or workpiece holder through closed-loop drive electronics. Through its asynchronous design and direct coolant circuit, it maintains thermal stability during sustained high-load operation in industrial metal-cutting applications.

The unit belongs to the liquid-cooled asynchronous motors product type, so heat is removed from the stator jacket by an external coolant supply rather than by ambient airflow. Mechanical stability is supported by balance quality R DIN ISO 2373, which helps limit vibration levels during spindle operation. The frame is prepared for flange mounting, and position and velocity are monitored by digital servo feedback with an integrated encoder for precise speed control without an additional sensor interface. The motor is supplied without a holding brake, so axes that must remain fixed at standstill need holding torque from the drive or a separate mechanical device. Standard bearings are used for rotor support, and a standard coolant connection simplifies piping. The electromagnetic package uses motor size 104, motor length C, and winding code AS, and the motor has no shaft seal ring or second shaft end.

Electrical power enters the stator through a plug-in connector on the housing, positioned on side A and mounted at the top of the frame to clear nearby components. Output torque is transmitted through a plain shaft, which simplifies coupling to the spindle nose. The single-ended shaft layout leaves the opposite end free of extra extensions, and the lack of a shaft seal reduces friction at the shaft exit. The housing-mounted connection also keeps cabling away from the shaft area and helps reduce clutter around the spindle nose.
