Product Description:

The ADF104C-B05TR1-AS06-C2N2 is a liquid-cooled asynchronous main spindle motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Engineered for high-speed metal-cutting centers and automated production cells, it converts inverter power into precise mechanical rotation for tooling or workholding spindles. Integrated coolant passages stabilize winding temperature, allowing continuous operation during demanding duty cycles typical of industrial machining and forming equipment. It is suited to applications that require repeatable speed control during rapid changes in spindle load.

The mechanical interface follows S DIN ISO 2373 balance quality, which helps keep vibration within limits for high-speed spindle service. It uses flange mounting, and the output is a plain shaft with a shaft-seal ring that helps keep coolant or lubricant out of the stator cavity. Position and velocity are returned to the drive through digital servo feedback, enabling closed-loop control without an external encoder. The motor is supplied without a holding brake, which reduces rotor inertia and supports faster acceleration. Size 104 laminations and a C-length stack provide the torque capacity expected for this motor class, while standard bearings and coolant fittings support installation in compact spindle assemblies.

Electrical integration is simplified by the stator's AS winding, which matches impedance tables used in compatible inverters. Three-phase supply lines enter from the machine's right side under the right-hand power entry arrangement, and the connector is located in a top-mounted power housing that helps clear chip conveyors and coolant trays. The rotor has no second shaft end, so coupling components remain limited to the drive side and the overall motor length stays compact. This layout also shortens nearby cable and hose routing, which helps reduce clutter around moving machine elements.
