Product Description:

The ADF134B-B05TC3-BS07-A2N1 is a liquid-cooled asynchronous motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Designed as a main spindle drive, it supplies continuous torque and speed control for machine tools and automated machining centers. Liquid circulation through the stator jacket removes waste heat, while a plain output shaft couples directly to precision tool holders, making the unit a compact source of rotational power in industrial automation lines. High thermal capacity keeps winding temperatures stable during extended high-speed duty cycles.

With a 134 frame size and length B construction, the motor offers a short axial dimension yet retains a generous bore for large drawbars. The BS winding code identifies the conductor dimensions and phase turns used by the matched inverter. The rotor is balanced to R DIN ISO 2373, which helps minimize residual vibration that could degrade surface finish. Installation uses flange mounting, and a standard bearing set supports radial and axial loads developed during cutting. The shaft is plain and is supplied without a seal ring, so any required sealing is provided externally. A top-side junction box forms the stator power interface, and liquid cooling maintains low thermal drift under continuous duty.

Position control is handled by a digital servo feedback package that integrates an encoder for closed-loop speed control and spindle orientation. Coolant is routed through an axial coolant coupling with a rapid-action connector that streamlines hose changes. Mains conductors enter through a power entry on side A, a configuration that frees the opposite side for tool changers and chip conveyors. For applications that manage deceleration electronically, the motor is supplied without a holding brake. The design excludes a second shaft end, reducing overhang mass, and the power terminal location on the top of the frame simplifies cable routing away from coolant lines.
