Product Description:

The ADF104C-B05TA1-BS07-D2N1 is a liquid-cooled asynchronous spindle motor manufactured by Bosch Rexroth Indramat as part of the ADF Main Spindle Motors series. Designed for rigid flange coupling to machining centers, the unit converts electrical energy into constant rotational motion for the machine’s primary cutting axis. The liquid cooling circuit keeps the stator temperature stable during prolonged high-speed operation, allowing the motor to deliver repeatable torque in automated production lines that rely on accurate spindle control.

This model meets balance quality class R DIN ISO 2373, which minimizes vibration during high-speed cutting. Position and speed data are delivered through digital servo feedback with an integrated encoder, allowing the controller to close velocity loops within one revolution. The laminated core uses length C, and the motor has a size 104 frame, which sets the axial depth and mounting circle. A flange mounting interface secures the housing to the machine. Power conductors terminate through a sealed plug-in connector, simplifying cabinet wiring. Standard rolling bearings support a shaft that is keyed and balanced together with the key for smooth rotation.

The electrical interface exits on Side A, and the connector is mounted on the top of the stator so cable routing can follow vertical energy chains. Coolant ports follow the series’ standard connection pattern, letting the motor pair with common hose fittings. The winding identification BS indicates the copper fill and insulation scheme chosen for high continuous currents. Because the unit is supplied without a holding brake, axis immobilization must be handled by the drive or external clamps. A shaft seal ring is fitted to protect the internal bearings from cutting fluid ingress, and the design omits a second shaft end on Side B to simplify coupling on single-ended spindle assemblies.
