Product Description:

The ADF100C-B05TA1-BS03-D2N1 is a main spindle motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. It is intended to drive machining spindles in automated production lines where continuous torque, precise speed regulation, and steady thermal control are required to maintain dimensional accuracy under prolonged load. Its operating role centers on delivering controlled mechanical power to the spindle while the drive manages speed changes commanded by the machine control. In this role, the motor suits machine tools that need stable spindle speed as cutting forces change during roughing, finishing, drilling, and other extended machining operations.

This model uses flange mounting, so the housing bolts directly to the machine frame and helps keep runout low at the cutting point. It uses a liquid-cooled asynchronous motor design, and coolant channels inside the stator remove heat close to the active parts rather than relying on external airflow. Position feedback is supplied by high-resolution motor feedback, enabling the drive to regulate speed and position with fine signal detail during spindle acceleration and steady-state operation. The power connector is placed on side A, and the connector body is mounted on the top of the frame to simplify cable routing when the motor is recessed inside a spindle headstock or enclosed machine housing.

Dynamic behavior is influenced by the rotor balance class of R DIN ISO 2373, which helps reduce residual vibration at operating speed. This variant is supplied without a holding brake, so the machine must provide spindle retention during shutdown through an external clamp or a controlled drive function. Torque is transmitted through a shaft with keyway, balanced with the entire key, which helps preserve balance after a pulley, coupling, or similar transmission component is fitted. The mains conductors use a rugged plug-in connector interface that resists loosening during repeated machine use and routine cable handling. Smooth rotation and dependable power connection are important when the motor runs through repeated speed changes and long production cycles.
