Product Description:

Bosch Rexroth Indramat builds the ADF104C-B05TA1-CS07-A2N1 as part of the ADF Main Spindle Motors series. This liquid-cooled asynchronous spindle motor is intended for machine-tool drives where continuous torque delivery and high speed stability are required. By circulating coolant through the stator jacket, the unit keeps winding temperatures low and supports sustained output inside enclosed machining centers. It is suited to spindle duties where cutting loads can change quickly, yet stable rotation must be maintained throughout the machining cycle.

The motor attaches to the machine frame by a flange mounting interface, so axial alignment is maintained without additional brackets. Rotor balance is graded to R DIN ISO 2373, which helps limit vibration that could affect surface quality during high-speed operation. Position and speed are monitored through digital servo feedback with an integrated encoder, allowing the drive controller to correct deviations during acceleration, deceleration, and steady running. The unit is supplied without a holding brake, so stopping must occur through controlled drive action rather than mechanical holding at standstill. A plain shaft exits the housing and is intended for direct coupling, with no keyway or threaded features to complicate the mating hub.

Electrical power reaches the stator windings from the motor connection block on Side A, while the cast connector housing sits on the top of the frame to keep cable routing clear of surrounding machine hardware. The three-phase supply is terminated through a sealed connector/plug, so leads can be disconnected without opening the motor enclosure. The rear of the motor is configured without a second shaft end, leaving the non-drive end available for feedback hardware, coolant routing, and related internal components. This arrangement helps keep the rear section compact and avoids extra exposed rotating features near the encoder area. The enclosed electrical interfaces and liquid-cooling layout suit machine interiors where cutting fluid, metal chips, and limited installation space are common.
