Product Description:

Bosch Rexroth Indramat manufactures the MAC112B-0-GD-1-B/130-A-1 I01250/S002 as part of the MAC AC Servo Motors series. Within a closed-loop motion axis, this permanent-magnet AC motor translates the drive amplifier’s current commands into proportional shaft torque and speed. It is intended for feed drives on machine tools, packaging lines, and general automation installations where repeatable positioning and moderate continuous duty are required.

The unit’s flange has a locating rim of 130 mm, providing a rigid centering interface that keeps runout below permissible limits when bolted to gearboxes or mounting plates. Its frame size designation of 112 indicates a stator outside diameter near that value, establishing the magnetic air gap and usable torque range. Because cooling relies exclusively on natural convection, additional fan kits are unnecessary, but ambient temperature must remain within the motor’s rated range to avoid thermal derating. The integrated blocking brake supplies 45 Nm of static holding torque; this spring-applied, electrically released device prevents unwanted motion on power loss. Mechanical length code B refers to the second lamination stack in the MAC family, giving the motor higher inertia than the shorter A variant and helping stabilize speed under load disturbances.

The stator winding set marked GD matches the electrical characteristics expected by compatible drive amplifiers, including current and back-EMF behavior. High-resolution commutation and positional data reach the controller through incremental encoder feedback, which carries sinusoidal signals and an index track for homing. Main power reaches the motor through a radial connector on side A, easing cable routing when adjacent axes limit available space. As a motor for analog drives, it is intended to operate with analog drive amplifiers that regulate velocity and position without digital fieldbus hardware.
