Product Description:

The MAC112D-0-ED-4-C-13-A-D-WI520LV-S005 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for closed-loop axis control in industrial automation where precise torque and velocity regulation are handled by an analog servo drive. The motor’s electromagnetic package, magnetic feedback, and mechanical interface are coordinated so the unit can be mounted directly onto gearboxes or couplings, while its tacho or encoder signals are returned to the drive for real-time correction.

This model uses a frame size of 112 mm, giving the housing the stiffness and bolt pattern expected for mid-range power output. The stack length marked as D extends the active iron to raise continuous torque without changing the mounting footprint. Under rated operating conditions, the rotor reaches 3000 rpm, a speed that matches the frequency limits of many analog regulators. Cooling relies on natural convection, so heat is dissipated through the ribs of the stator case without an external blower. The winding code ED identifies the phase resistance and inductance values expected by the analog drive, supporting current-loop stability and predictable thermal rise.

For position and velocity sensing, the motor is supplied with tacho feedback and an incremental or absolute encoder, allowing both speed feedback and higher-resolution position monitoring. The designation motor for analog drives indicates that command inputs and current control are handled by ±10 V or similar analog references rather than fieldbus messages. A built-in tacho generator produces 3 V/1000 rpm, giving the drive a proportional voltage suited for speed regulation. Tacho quality is graded as standard, meaning ripple and linearity stay within the tolerances expected for general-purpose motion axes without special precision demands.
