Product Description:

The ADF132D-B05TA1-AS23-A2N1 spindle motor is manufactured by Bosch Rexroth Indramat and belongs to the ADF Main Spindle Motors series. Classified as a liquid-cooled asynchronous motor, it drives the main spindle in CNC machining centers and other automated equipment that require continuous torque and efficient heat removal. Its integration with Indramat drive controllers is supported by a high-resolution feedback interface, and the unit is prepared for direct flange installation inside machine frames to simplify alignment during installation.

With a frame size of 132, the stator core supplies a torque level appropriate for medium-power spindles, while the extended stack length designated as D increases magnetic loading without changing the flange diameter. An internal brake delivers 30 Nm of holding torque so the spindle can remain locked during tool exchange or maintenance. Position data is issued through high-resolution motor feedback, enabling tight speed and position loops in the drive controller. Mechanical attachment is achieved through flange mounting, and standard rolling-element bearings keep radial runout within machining tolerances.

Dynamic balance is graded at R DIN ISO 2373, which helps limit vibration during sustained high-speed rotation. Electrical power is supplied through a connector plug that exits toward Side A with the housing positioned on top of the stator, simplifying cable routing inside compact enclosures. The brake is an electrically actuated release holding brake and remains engaged whenever the control system is de-energized. Torque is transmitted through a plain shaft with no second shaft end, and there is no shaft seal ring because the machine tool coolant circuit already encloses the motor. The motor also uses a standard coolant connection and winding code AS.
