Product Description:

The MAC112C-0-HD-4-C/130-A-0/WJ520LX/S05 is a servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, it converts commanded current into controlled torque and speed for positioning axes, conveyor sections, and other process equipment. The unit is suited for packaging equipment, transfer systems, and general-purpose machine axes where the drive must regulate torque changes smoothly during acceleration and steady running. Its feedback arrangement supports precise motion in industrial automation, especially where repeatable speed control is required under varying load conditions.

Thermal management relies on natural convection, so heat leaves the housing through surface radiation and airflow without auxiliary fans. The motor has a centering diameter of 130 mm and a frame size of 112, which fit mounting flanges commonly used on medium-power axes. Stack length code C indicates the active core depth, and the motor reaches a rated shaft speed of 2000 rpm. Velocity feedback to the analog drive comes from an internal tachogenerator that produces 3 V/1000 rpm, and the sensor assembly can be configured for incremental or absolute encoder signals to match controller requirements.

Electrical performance is tied to winding code HD, which corresponds to the resistance, inductance, and current limits that the analog amplifier must observe. Power conductors terminate at a connector on side A, which can simplify cable routing when the motor is installed with its shaft horizontal. Because there is no blocking brake, axis holding torque must be supplied by the drive or by an external mechanical lock during power-off conditions. This layout also supports reliable speed measurement for closed-loop velocity regulation without additional sensors.
