Product Description:

The ADF134D-B05TC3-BS00-C2V1 main spindle motor is manufactured by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous unit intended to drive machine-tool spindles where continuous torque and stable operating temperature are important. As part of an integrated drive line, the motor converts electrical energy into high-speed rotation for milling, turning, or grinding centers in industrial automation. Its layout suits spindle applications that require steady performance during long machining cycles.

With a frame size of 134 and the elongated D length, the motor has a longer iron stack for higher spindle power. The motor uses flange mounting, so the stator seats directly against the machine headstock. Winding code BS matches the stator to standard Indramat inverters, and the cooling jacket circulates fluid because the unit is a liquid-cooled asynchronous motor, which helps keep winding temperature under control during sustained operation. Mechanical output is delivered through a plain shaft with a shaft seal ring, while electrical power enters through a top-mounted junction box with the conduit facing Side A. Feedback is not included because the motor is supplied without an encoder.

The rotor uses a balance grade of R DIN ISO 2373, which helps limit vibration during high-speed spindle operation. The spindle is supported by heavy-duty bearings that absorb radial and axial loads encountered in machine-tool service. Coolant connections use an axial rapid-action coupling, allowing the cooling circuit to be connected quickly and securely. The motor is supplied without a holding brake, so stopping torque or load holding must be provided by the machine control and drive system. Torque is transmitted through a single shaft end, while the opposite end remains closed.
