Product Description:

The ADF132C-B05TA1-BS03-B2N1 main spindle motor is produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Classified as an asynchronous motor, it supplies steady torque for automated machining, grinding, and milling axes. A closed coolant jacket transports heat away from the stator so thermal drift is minimized during long production cycles, and its mounting interface lets the motor attach directly to a machine headstock without additional brackets. This arrangement supports stable operation during long duty periods in machine tools that need repeatable spindle performance.

The motor has a 132 frame size and a motor length C, providing the active iron volume needed for high continuous power in a compact envelope. Mechanical attachment is through flange mounting, which provides radial rigidity at the tooling interface. Internally, a liquid-cooled laminated core promotes a stable winding temperature, while the absence of a holding brake reduces mass and inertia for rapid spindle acceleration. The drive transmits position data through high-resolution motor feedback, enabling precise contouring when paired with a digital controller. Electromagnetic behavior is set by the BS winding code, allowing the inverter to match current and torque characteristics correctly. A standard bearing set supports the rotor under radial and axial cutting loads, and the layout is suited to applications where the spindle is controlled by the drive rather than held by a brake at standstill.

The motor meets R DIN ISO 2373 for dynamic balance, so residual vibration remains within spindle-class limits. The output uses a shaft with keyway that is balanced with the full key, and no shaft seal ring is fitted because the motor is intended for closed, pressurized coolant circuits. The housing uses a top power connector oriented toward Side A, which keeps the cable exit predictable and simplifies routing within the machine enclosure. Standard coolant fittings and the lack of a second shaft end help keep the overall envelope consistent for machine layout. This layout is useful in compact spindle housings where cable clearance and coupling space are limited.
