Product Description:

The ADF104C-B05TR1-CS07-A2N2 is a main spindle motor produced by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. Designed for machine-tool automation, it converts electrical energy into the rotary motion required by milling, turning, and grinding spindles while permitting closed-loop control from the associated drive electronics. This arrangement allows the motor to respond quickly to commanded speed changes and maintain stable spindle operation as cutting loads vary. Its construction supports high cycle rates in continuous production lines.

The motor uses a size 104 frame and a C length, a combination that provides the rotor volume needed for elevated torque without extending the machine footprint. Installation is via flange mounting, allowing the body to seat directly against the spindle housing and eliminating alignment brackets. A plain shaft is supplied, so drive torque is transferred through a shrink-fit or keyed hub without adding external bearing elements. For motion control, the integrated encoder delivers digital servo feedback, giving the drive controller the position and velocity information needed for precise tool positioning and dynamic acceleration profiles.

The motor is supplied without a holding brake, so any axis that must maintain position at standstill relies on mechanical clamping or drive torque instead of an internal brake. Vibration levels are controlled by the S DIN ISO 2373 balance grade, making the rotor suitable for high spindle speeds with minimal runout. Electrical characteristics are set by the CS winding code, matching the stator impedance to compatible ADF inverters and enabling full current delivery through the right-side power plug positioned at the top of the terminal box. As a liquid-cooled asynchronous motor, thermal energy is removed by circulated coolant rather than external airflow, which helps support continuous duty in enclosed machine cabins and reduces heat buildup around the motor housing.
