Product Description:

The ADF100B-B05TA1-BS03-B2N1 main spindle motor is produced by Bosch Rexroth Indramat and belongs to the ADF Main Spindle Motors series. Designed for continuous spindle duty, it supplies rotary power for CNC machining centers, lathes, and automated drilling stations that run under high cutting loads. Integrated coolant channels circulate fluid around the stator to remove heat quickly and support stable operation during long machining cycles. When paired with a compatible digital inverter, the motor gives the spindle axis controlled acceleration, steady running speed, and repeatable response during changing load conditions.

Its frame size is 100, and the active stack length is B, which gives the motor a compact footprint with enough mass to support sustained spindle use. The housing uses flange mounting, allowing accurate alignment to the machine structure and a secure connection at the mounting face. The rotor uses a shaft with keyway balanced to the entire key, which supports positive torque transfer to pulleys, couplings, or spindle drive elements. Vibration performance meets R DIN ISO 2373, helping the motor run smoothly in applications where surface finish and bearing stability matter.

This unit is a liquid-cooled asynchronous motor, so heat is carried away by the coolant circuit instead of relying on external airflow around the housing. Motion data is supplied by high-resolution motor feedback, allowing the drive to monitor rotor behavior closely during speed changes and load variations. The main conductors connect through a connector plug mounted on the top of the housing and oriented to Side A, which helps keep cable routing orderly inside enclosed spindle compartments. The motor does not include a holding brake, so stopping and speed control are handled by the drive system rather than by a mechanical brake.
