Product Description:

The MAC112B-0-PD-2-C/130-A-2/S018 is an AC servo motor manufactured by Bosch Rexroth Indramat and positioned within the MAC AC Servo Motors series. Designed as a torque-controlled rotary drive, it interfaces with analog servo amplifiers to move machine axes in automated assembly lines, printing presses, and material-handling stations. By converting commanded current into proportional mechanical output, it supports closed-loop motion sequences that demand consistent velocity regulation and repeatable positional accuracy. Its operating style suits transfer axes that must start, stop, and reverse smoothly while maintaining predictable response under changing load conditions. In packaging and indexing equipment, that behavior helps the machine hold timing relationships between driven sections without relying on oversized mechanics.

The integrated heavy-duty blocking brake secures the shaft when power is removed, and its holding capacity is 60 Nm, so vertical loads stay fixed without external clamps. A 130 mm centering pilot aligns the housing to gearboxes and frames. Heat from the windings leaves through natural convection, so no fan or liquid circuit is needed. Under rated excitation the rotor turns at 1500 rpm, matching analog controllers that supply sinusoidal current. This arrangement supports compact installations where quiet operation and simple cable routing are preferred. Passive heat removal also reduces maintenance points and avoids introducing forced airflow into enclosures that handle dust or paper debris.

Speed feedback comes from an internal tacho feedback generator that produces 3 V/1000 rpm, providing a direct speed signal for the connected amplifier. Power leads enter through a connector on side A, simplifying wiring in tight enclosures. Electrical parameters follow winding code PD, so the motor matches the current and voltage characteristics expected by compatible drives. The motor occupies size 112 with length code B and is classified as a motor for analog drives, fitting machines that favor direct tacho signals over digital encoders. That combination is useful in retrofit systems where analog velocity loops remain in service and feedback simplicity is more important than encoder resolution.
