Product Description:

The ADF134D-B05TC3-BS07-C2N1 is a liquid-cooled asynchronous motor in the ADF Main Spindle Motors series from Bosch Rexroth Indramat. It is intended to drive machine-tool spindles and other continuous-duty axes in automated equipment, where closed-loop operation helps maintain accurate rotational control. The internal cooling jacket carries heat away from the motor during sustained operation, which supports stable output over long machining cycles. It is supplied as a ready-to-mount assembly for direct use with compatible IndraDrive controllers on milling, boring, or grinding equipment.

The motor has a frame size of 134 with a D length code, giving it a deep stator stack for continuous power output. Rotor vibration is controlled to R DIN ISO 2373 balance quality, which helps maintain smooth running at operating speed. The housing uses flange mounting, allowing direct installation on the machine headstock. Coolant enters through an axial coolant connection with a rapid-action coupling, which supports quick hose connection and removal. Electrical terminations exit on Side A, and the power connection housing is mounted on the top of the machine so cable routing stays clear of chip flow paths. The motor uses winding code BS, and standard rolling-element bearings support the shaft.

Control resolution comes from integrated digital servo feedback, which sends position and speed data to the drive in real time. The motor is supplied without a holding brake, so power-off holding must be handled by drive torque or an external clamping device. Power enters through a junction box, which helps protect field wiring and keeps the connection area away from coolant spray. The rotor uses a plain shaft, and a shaft seal ring helps keep coolant out of the internal cavity. The design also omits a second shaft end on side B, which shortens the overall envelope for compact spindle housings.
