Product Description:

The ADF134D-B05TA0-BS06-A2N1 main spindle motor is produced by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. It is an asynchronous unit intended for continuous rotation in CNC and automated machining centers, where it acts as the primary drive for the spindle and interfaces with external vector drives for speed and torque control. Its operating role is to deliver steady torque across the speed range required for drilling, milling, and similar machining processes.

With a frame designation of 134 and an internal length code of D, the rotor and stator geometry provide torque suited to medium-power cutting tasks. Installation is by flange mounting, which aligns the motor face to the machine bed while supporting the plain shaft. Overall vibration is held to balance class R DIN ISO 2373, which helps protect the standard rolling-element bearings at high spindle speeds. The power conductors exit through a connector on side A mounted on the top of the stator, keeping cable runs clear of chips and coolant. No second shaft end is provided, and the design omits a shaft-seal ring, so integration is simplified in closed-end housings that use the machine's own coolant barrier for contamination control.

Thermal energy is removed through an internal water jacket, and fluid enters through the axial connection with a 1/4-inch thread for direct hose attachment without restrictive elbows. Motion control accuracy is maintained by the integrated Digital servo feedback system that relays position and speed to the inverter. For installations that depend on regenerative drive torque to hold position, the motor is supplied without a holding brake. The electromagnetic circuit follows winding code BS, matching impedance and current density to compatible drives. It belongs to the Liquid-cooled asynchronous motors product class, which suits enclosed spindle compartments and helps reduce airborne contamination.
