Product Description:

The ADF100D-B05TA1-AS07-A2N1 is a main spindle motor from Bosch Rexroth Indramat's ADF Main Spindle Motors series. Built for direct installation in CNC equipment, the unit delivers regulated rotary power to cutting, drilling, and grinding spindles so that surface speed and torque remain stable during automated machining cycles. Coupling directly to the machine flange removes intermediate belts, and the integrated encoder interface lets the drive controller manage speed and position without mechanical backlash. It is intended for machine tools that require smooth acceleration, stable speed regulation, and direct mechanical coupling between the drive and spindle.

Dynamic behavior begins with a rotor balanced to R DIN ISO 2373, a grade that limits vibration at high speed. The housing supports flange mounting, allowing the motor to attach directly to the machine structure, and a sealed stator chamber houses standard bearings for predictable operation. Electrical power is introduced through a connector plug that exits on Side A and sits on the top of the frame, keeping cables clear of coolant lines. Motion data are supplied by digital servo feedback with an integrated encoder, giving position information at startup and fine-resolution velocity control throughout the duty cycle. This feedback arrangement supports synchronized spindle functions and rapid correction when cutting load changes occur. The unit is supplied without a holding brake, so any static locking torque must be provided by the drive or an external clamp.

Heat is removed by a liquid-cooled asynchronous design that uses a standard coolant connection to stabilize winding temperature during long machining runs. Continuous coolant flow helps the motor maintain thermal stability during long periods of heavy cutting or repeated duty cycles. The motor uses motor size 100 with motor length D, giving a compact package suited to medium-power spindle requirements. Drive torque is transmitted by a plain shaft, and no shaft seal ring is fitted, so external sealing is required when pressurized media are present. A single shaft end on side B reduces overhung mass at the opposite end of the motor, and winding code AS matches the stator impedance to ADF-series inverters for stable current control.
