Product Description:

The ADF134C-B05TA0-BS06-A2N2/S032 main spindle motor is produced by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. Designed for high-speed machining centers and comparable automation tasks, it supplies controlled rotary motion to tool spindles while an internal cooling circuit removes heat generated during continuous operation. The ADF134C-B05TA0-BS06-A2N2/S032 unit interfaces with a drive controller through a sealed power plug and is intended to integrate into closed-loop spindle drives used across automated production cells. This arrangement supports spindle applications that require stable speed and repeatable response under changing cutting loads.

Frame size 134 sets the outer diameter and bolt circle so the housing matches heavy spindle castings, while length code C indicates extended active steel for higher torque without enlarging the footprint. With flange mounting, the motor bolts directly to the machine wall, which helps maintain alignment and reduces the need for adapter plates. As a liquid-cooled asynchronous motor, it carries coolant through internal channels so full-load duty can continue inside sealed enclosures. Position data is returned through digital servo feedback, allowing the drive to correct speed deviations in real time. The cooling circuit uses an 1/4" axial port, which keeps hoses clear of tool magazines and helps simplify hose routing.

The power connector exits toward Side A power exit, and the connector shell is located on the top of that face to keep cabling away from slideways. A plain shaft is supplied so custom tool clamping hardware can be ground or shrink-fitted without keyway constraints. The motor operates without a holding brake, so stop position must be maintained by drive torque or a mechanical clamp. This layout suits spindle systems that rely on external holding methods when motion is stopped.
