Product Description:

The ADF132D-B05TA1-AS03-D3N1 spindle motor is manufactured by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous drive for milling, turning, and grinding centers that operate continuously. Heat is removed through an internal coolant jacket, permitting constant torque in automated production lines. The type code identifies the frame size, active length, winding, and connection layout for matching with Indramat inverters and machine interfaces.

Within the type code, the frame size of 132 refers to the stator outside diameter, while the active length index D extends the iron core to raise continuous power density. Installation is carried out through flange mounting, which provides a rigid axial seat against the machine headstock. Rotor angle is reported by a high-resolution motor feedback system that supplies the drive controller with precise positional data for closed-loop speed control. Balance is graded to R DIN ISO 2373, which limits residual vibration and helps protect the host spindle bearings. Standard deep-groove bearings carry radial and axial loads, the AS winding code sets the electrical resistance and inductance profile, and the power connector exits toward Side A at the top of the housing through a molded connector and plug interface.

This motor is supplied without a holding brake, so braking or clamping must be provided by the machine tool's mechanical system. Torque is transmitted through a shaft with a keyway, balanced with the entire key, and a shaft seal ring helps block coolant from entering the bearing chamber. For auxiliary encoders or alignment tasks, the unit includes a second shaft end on Side B. Coolant lines attach through a standard coolant connection, matching the hose sets used throughout the ADF portfolio.
