Product Description:

The ADF100D-B05TB1-AS03-A3N1 main spindle motor is manufactured by Bosch Rexroth Indramat as part of the ADF Main Spindle Motors series. It is intended for machine-tool spindles and other high-duty axes in automated production lines where steady rotary output is required during changing process loads. The motor converts inverter output into continuous rotation and is suited to applications that need stable speed behavior during acceleration, load variation, and extended operating periods.

Mechanical integration uses flange mounting, which places the 100-frame housing directly against the machine face for rigid installation. The D motor length adds stator depth for higher continuous power in the same basic frame size. A high-resolution motor feedback system sends position data to the drive so speed and torque can be regulated precisely during spindle operation. Power conductors exit on side B, and the connector is mounted at the top of the housing to help route cables away from the coolant lines. The plain shaft transmits torque with low runout, and because no shaft seal ring is fitted, external sealing is required in wet areas. Cooling water enters through the standard connection, and the AS winding code is intended for compatible ADF-class inverters.

Dynamic balance is graded R DIN ISO 2373, which helps limit vibration at high spindle speeds and supports cutting accuracy. The motor is supplied without a holding brake, so stopping or holding torque must be provided by the drive or by an external clamp. It is a liquid-cooled asynchronous motor, so heat is removed continuously during operation rather than by external airflow. The shaft includes a second shaft end, which can be used for an auxiliary encoder or a manual handwheel. Power is delivered through a sealed connector plug, and the motor uses standard coolant and bearing arrangements.
