Product Description:

The MAC112D-0-ED-4C/130-A2/MR121ZS018 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. In automated equipment, it can couple directly to ball screws, belt stages, or gearboxes to position loads with low settling time and stable speed regulation. The motor converts electrical drive commands into controlled rotary motion for indexing, synchronized axis travel, and repeatable handling cycles. It is suitable for packaging, assembly, and material-transfer systems that depend on consistent servo response during frequent start, stop, and speed-change sequences.

The motor is cooled by natural convection, so heat is released through the aluminum housing without fans or liquid circuits. Its nominal shaft speed of 3000 rpm supports direct coupling to common transmission ratios while keeping the operating range suitable for general servo applications. Frame size 112 sets the stator diameter and the mechanical interface dimensions used for flange mounting. Electrical behavior is indicated by winding code ED, which corresponds to the rated voltage, current, and back-EMF expected by the drive amplifier. This arrangement avoids auxiliary cooling hardware and keeps the motor suitable for installations where a simple external layout is preferred.

Axial build class D extends the active magnetic length to increase continuous torque without enlarging the mounting footprint. Position and speed control can use an incremental tacho feedback device for speed-proportional output, while an absolute encoder can be used when immediate position information is required after power-up. Classified as a motor for analog drives, the unit is intended for servo systems that use analog command interfaces such as ±10 V references. This allows the motor to operate with established control platforms that still rely on analog signal handling rather than fully digital drive communication.
