Product Description:

The ADF132B-B05TA1-BS06-A2N1 main spindle motor is produced by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous unit designed to drive machine-tool spindles and other high-speed axes in automated production lines. By converting electrical power into controlled torque and speed at the spindle, the motor supports precise cutting, drilling, and grinding operations that require stable rotation and fast acceleration. Its integration with inverters allows closed-loop control under variable load.

This motor belongs to the liquid-cooled asynchronous motors product type, so cooling liquid circulates through internal channels and removes heat generated by the stator. The mechanical interface uses flange mounting, allowing direct attachment to a machine frame without additional brackets. Position and velocity signals are handled through digital servo feedback, which sends encoder data to the drive for accurate speed regulation. Rotor balance conforms to R DIN ISO 2373, which helps limit vibration during high-speed operation. The motor uses a motor size 132 frame with a B length code, providing increased active iron while keeping the housing dimensions consistent with this frame class.

For braking duty, the unit is delivered without a holding brake, so motion retention must be handled by the external drive or by mechanical locks. The rotor uses a plain shaft, and no shaft seal ring is fitted, a layout that favors lower friction in liquid-cooled applications. Power enters through a connector plug mounted on the top of the motor housing and oriented toward Side A, which helps with cable routing in compact machine layouts. The electrical setup uses winding code BS, which matches drive inverters assigned to this frame category. The opposite end does not include a second shaft, so the motor is not arranged for through-spindle tooling.
