Product Description:

The MAC112C-0-ED-4-C/130-A-0/WI524/S05 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a motor for analog drives that converts commanded current into precise torque for automated tooling, pick-and-place equipment, and material transfer stations. Its internal tachogenerator supports speed feedback for closed-loop operation. The motor has no blocking brake, so applications that must hold position at standstill need an external holding method.

A centering diameter of 130 mm aligns the housing concentrically with the driven load and simplifies repeatable flange mounting. The rotor is designed for a nominal speed of 3000 rpm, allowing the drive to follow high-frequency reference changes without overshoot when paired with proper gear ratios. Winding code ED identifies the copper fill and insulation arrangement used for this motor so it can deliver rated torque at standard supply voltages. Heat is removed through natural convection, and fins on the stator surface dissipate losses into ambient air without forced ventilation hardware. For velocity feedback, the built-in tacho produces 3 V/1000 rpm, giving the controller a linear voltage proportional to shaft speed during regulation.

Frame designation 112 indicates the stator diameter, while length code C uses a longer active stack to increase continuous torque without changing the mounting face. Position information is supplied by an incremental encoder with standard mounting, and it works alongside the tacho to support fine position interpolation and stable speed control. Power and ground conductors route through a connector on side A, keeping electrical access on one face of the machine layout. This cable orientation can simplify routing where the motor is installed close to guards, gearboxes, or other adjacent hardware.
