Product Description:

The ADF160C-B05TB1-BS03-D3V2 is a liquid-cooled asynchronous spindle motor engineered by Bosch Rexroth Indramat for high-speed machining equipment. It belongs to the ADF Main Spindle Motors series and removes heat through an internal coolant jacket so rated torque can be maintained during extended production. Serving as the primary drive in milling, turning, and grinding stations, the motor converts inverter energy into precise rotational motion that supports automated material removal and repeatable surface quality in industrial automation. This cooling method helps the motor stay thermally stable when the spindle repeatedly accelerates, decelerates, and holds demanding cutting speeds. Liquid cooling also reduces the amount of heat released into the surrounding machine structure during long cutting cycles.

Dynamic smoothness is achieved through a balance grade of S DIN ISO 2373, limiting residual vibration at elevated speed. The rotor is carried by heavy-duty bearings that increase axial and radial load capacity for aggressive cutting passes. Machine integration is simplified by the flange mounting interface, allowing the housing to bolt directly to the spindle head. Dimensional coding follows a motor length C designation that sets the active stack height, while the frame size 160 identifies the stator diameter and coolant envelope. This arrangement supports stable spindle operation during continuous mechanical loading.

Position control relies on high-resolution motor feedback that delivers accurate rotor angle data to the drive. Power is transmitted through a second shaft on Side B, while torque reaches the tooling through a shaft with keyway that is balanced with the key. The three-phase supply enters through a plug-in power connection mounted on the top of the housing and oriented toward Side B for streamlined cable routing. Internally, winding code BS identifies the electromagnetic layout, while a standard coolant port ties into the machine’s cooling circuit. A shaft-seal ring prevents fluid ingress, and the unit is supplied without a holding brake. The feedback system also supports accurate spindle orientation for tool changes and other positioning tasks at the machine head.
