MAC112B-0-PD-3-C/130-A-0/S037

Bosch Rexroth Indramat manufactures the MAC112B-0-PD-3-C/130-A-0/S037 within the MAC AC Servo Motors series. Classified as a motor for analogue drives, it converts the velocity commands of legacy drive amplifiers into mechanical motion for industrial positioning and process equipment. Its design aligns with the mechanical envelope and mounting conventions common to the MAC family, allowing straightforward exchange or upgrade inside existing automation lines.

The motor belongs to size code 112, establishing its frame dimensions and shaft height, while the centering flange measures 130 mm to guide precise seating against the machine plate. Heat is removed solely through natural convection, so no external blower or liquid circuit is required. The windings follow code PD, which defines the copper fill and resistance profile used by analogue current regulators. Under rated excitation the rotor runs at 1500min-1, a speed that pairs with standard 50 Hz or 60 Hz gear ratios in material-handling lines. Tacho feedback is produced with standard quality filtering to maintain velocity accuracy inside the analogue loop.

No holding torque is provided because the blocking brake is Not Present; applications that need standstill security must add an external clamp or rely on drive torque. Position and speed data exit the rear thanks to the optical encoder plus a second shaft end equipped for tachofeedback and second shaft end coupling. Power enters through a connector to side A, simplifying cable routing inside cabinets where the motor faces left. The mechanical depth corresponds to motor length code B, ensuring clearance when swapped with other “B” units in the series. Velocity feedback produces 3V/1000min-1, giving analogue controllers a linear signal for closed-loop regulation without additional scaling circuitry.
