Product Description:

The ADF184D-B35LC3-DS07-C2N1 is a main spindle motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Classified as a liquid-cooled asynchronous motor, it supplies continuous drive power for CNC milling, grinding, and turning centers. Integrated coolant passages remove heat directly from the stator, allowing long duty cycles at elevated torque without enlarging the machine envelope. The design targets applications where precise speed regulation and compact installation are both required, and it interfaces with Rexroth inverters for coordinated multi-axis control.

Rotor and stator assemblies are balanced to R DIN ISO 2373, minimizing vibration that could affect surface finish. Coolant flows through an axial connection with a rapid-action coupling, so hoses can be disconnected quickly. Position and velocity are reported by digital servo feedback with an integrated encoder, which sends absolute data to the controller over a single cable. The electromagnetic core is built in length D, and together with motor size 184 it supports high overload capacity while keeping mass moderate. Installation is simplified by flange and foot mounting, giving users either face or base attachment points. Standard bearings absorb combined loads, the motor is delivered without a holding brake, and side B lacks a second shaft end to shorten the overall spindle chain.

Power enters through leads routed to side A, with the connection housing located on the left to align with common cable ducts. Inside the junction box, field wiring is terminated under screw clamps protected from coolant spray. The drive end uses a plain shaft that mates directly with hydraulic chucks or shrink-fit sleeves, eliminating key and keyway stress. A shaft seal ring blocks coolant ingress, while winding code DS matches resistance and inductance to Rexroth converters for high-speed, high-frequency operation.
