Product Description:

The ADF132D-B05TR1-BD03-B3S1 is a main spindle motor created by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Classified as a liquid-cooled asynchronous motor, it is engineered to drive milling, turning, or grinding spindles where continuous torque and thermal stability are required in industrial automation. Liquid cooling removes heat directly from the stator and supports high duty cycles, while the integrated sensor set supplies precise rotor position data to the drive controller. It is suited for machining centers and production cells that require high speed and steady torque.

The motor is balanced to R DIN ISO 2373, so residual vibration stays within limits suited for precision surface finishes. A spindle bearing set on the drive end supports radial and axial loads typical of cutting forces. Position information is supplied through high-resolution motor feedback, enabling tight velocity loops and accurate tool positioning. The stator frame follows size code 132, and its active stack extends to length code D, providing additional magnetic depth for higher power density. Coolant is routed through a standard connection, and the housing remains under liquid flow to carry away losses without external fans. The keyed shaft is balanced with the full key installed, minimizing runout when tooling components are mounted.

The unit is supplied without a holding brake, so static load retention must be managed by the drive or external clamps. It attaches to the machine frame via flange mounting, and the power leads enter from the right with the terminal housing on top of the stator. Electrical energy is delivered through a connector plug, which allows the motor to be disconnected without hardwiring. No shaft seal ring is fitted, so external sealing measures are required if the spindle operates in a flooded environment. The rotor is machined with a second shaft end, allowing an encoder, auxiliary fan, or belt drive to share rotational power.
