Product Description:

The ADF134D-B05TC3-BS07-A2N1 is an asynchronous spindle motor produced by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. It converts electrical energy into rotational power for machine tools and other automation equipment that require high thermal stability and steady spindle speed during long duty cycles. This motor type is intended for spindle applications where continuous machining can generate significant heat and demand stable operating behavior. The ADF134D-B05TC3-BS07-A2N1 designation identifies the 134 frame platform, D length class, and BS winding code. Its construction omits an integrated holding brake, so position retention must be handled by the drive or by an external clamping device.

Mechanical integration is simplified by flange mounting, which aligns the motor to the machine frame without additional brackets. Rotor symmetry is set to the R DIN ISO 2373 balance grade, which helps limit vibration that could affect surface finish during high-speed operation. Thermal exchange occurs through an axial rapid-action coolant coupling, allowing coolant hoses to be latched or released quickly while maintaining liquid flow around the stator jacket. Positional data is returned through digital servo feedback from an integrated encoder, enabling closed-loop speed regulation over the full speed range. The cooling arrangement supports consistent thermal behavior during extended machining periods. The motor uses liquid-cooled asynchronous construction to keep winding temperatures low under sustained spindle loads.

Electrical power enters through a junction box in a top-mounted housing, and the leads exit through a power exit on side A so cable routing follows the spindle axis. With the connection point above the motor body, hose and cable runs can be guided away from the rotating shaft area. The drive shaft is a plain shaft without keys or threads, and there is no second shaft end on side B. A standard rolling-element bearing set supports the rotor, and the absence of a shaft seal ring means the coolant circuit must remain leak-free to prevent ingress. This layout keeps the mechanical interface straightforward for direct coupling to a single tool flange.
