Product Description:

The MAC112C-0-ED-4-C/130-A-0/WI520L/S05 AC servo motor is manufactured by Bosch Rexroth Indramat and is part of the MAC AC Servo Motors series. Intended for analog drive systems, the unit supplies continuously regulated torque and speed to automated axes, conveyors, and tooling heads. It links the commanded current from the drive amplifier to mechanical rotation, providing closed-loop response that supports precise industrial motion sequences across a wide range of manufacturing cells.

A centering diameter of 130 mm aligns the stator housing with gearboxes or machine frames. Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, balancing dynamic response and bearing life. Heat is removed by natural convection, so the surrounding air must allow free circulation instead of relying on forced cooling. The three-phase power leads are routed through a connector on side A, which helps when cable runs approach from that direction. Magnetic characteristics are set by the ED winding, which matches the resistance and inductance values expected by the analog drive electronics. The motor is supplied without a blocking brake, so vertical axes must use external clamping when power is removed.

Compact mechanical proportions are established by length code C and motor size 112, which provide sufficient stack depth for moderate continuous torque while keeping mass low for rapid acceleration. The integrated tachogenerator outputs 3 V/1000 rpm, a level matched to conventional analog velocity regulators, and this signal is complemented by an incremental encoder that supplies position data when tighter angle control is needed. For applications that demand higher resolution, the factory-installed incremental or absolute encoder with tachofeedback option provides additional position data without changing the motor body.
