Product Description:

The ADF160B-B05TA1-CS03-B2N1 is a liquid-cooled asynchronous main spindle motor manufactured by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. Installed in CNC machining centers and other automated production lines, it supplies the primary rotary drive for cutting tools or work-holding spindles, translating drive commands from the inverter into continuous, thermally stable torque for high-duty industrial tasks. Standard bearings carry radial and axial forces, and the liquid jacket connects through a standard coolant interface to remove heat. Liquid cooling helps maintain winding temperature during prolonged machining cycles, supporting stable output during continuous-duty operation.

The rotor and stator follow balance class R DIN ISO 2373, limiting residual vibration that can transfer to the finished surface. The motor has size 160 and core length code B, a combination that sets the active iron volume and the available power range. Position accuracy is maintained through high-resolution motor feedback, which provides fine incremental angle data to the drive controller. Mechanical attachment uses flange mounting, allowing the housing to bolt directly to the machine frame without additional adapters. The shaft has a keyway and is balanced with the entire key to support smooth rotation; there is no shaft seal ring, so external sealing must be provided when oil mist or cutting fluid can reach the coupling zone. A second shaft end is not provided, and the motor is supplied without a holding brake, so external clamping devices are required when standstill locking is needed.

The electrical connection uses a connector plug mounted on the top of the housing, and the power cable exits on side A to simplify routing inside vertical cabinets. This layout helps keep the cable path clear of nearby machine components and reduces sharp bends near the housing. Winding code CS identifies the conductor profile and insulation system used for this model, which supports use with designated ADF inverters. Because the coolant passes directly around the stator, thermal drift is reduced, which helps preserve feedback linearity and bearing life during continuous high-speed operation.
