Product Description:

Bosch Rexroth Indramat builds the MAC112B-2-GD-4-C/130-A-2/WI524LV/S013 for the MAC AC Servo Motors series. Classified by the manufacturer as a motor for analogue drives, it is integrated into closed-loop control chains to provide commanded torque and speed to automated presses, gantries, and packaging stations. The product couples its electromechanical output directly to machine shafts, allowing the associated drive amplifier to position or regulate load motion under real-time feedback.

The shaft incorporates a blocking brake that can apply 60 Nm of static holding torque to secure vertical or suspended loads when power is removed. A dedicated external blower rated at AC 115 V forces airflow across the housing; this keeps the windings within thermal limits during continuous duty. Accurate mechanical alignment is simplified by a 130 mm centering diameter on the flange, while Axial Surface Cooling directs the forced air parallel to the frame for even heat removal. Power is delivered through a Connector to side A, so both mains and motor cables exit the same face of the cabinet. The feedback configuration supports tachofeedback plus either incremental or absolute encoder signals, enabling the analogue controller to observe actual speed without conversion delays. Standard tacho quality guarantees consistent voltage-per-rpm characteristics, and the motor length coded “B” balances rotor inertia against peak torque rise time.

Additional construction features reinforce application flexibility. The integrated Heavy-duty Blocking Brake is matched to the frame’s mass moment, permitting emergency stops without external clamps. Electrical performance is defined by winding code GD, which establishes phase resistance and inductance values used by the drive for current limit parameters. Position feedback is supplied through an incremental encoder with standard mounting, ensuring plug-compatible replacement in existing MAC installations. Frame identification as size 112 provides interchangeability across the series, and the overall geometry remains within the B-length envelope so the unit can slide into machines originally engineered for the same footprint.
