Product Description:

The MAC112D-0-ED-4-C/130-A-0/WJ520LX/S05 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts controller commands into proportional torque and speed for positioning or continuous-duty axes in industrial automation equipment. Its feedback arrangement allows the connected amplifier to monitor motor behavior during operation and correct for load-related speed changes. It is commonly used on packaging, transfer, and handling axes where repeatable rotation is more important than networked communication features. Its form factor follows the MAC platform used in many established machine designs.

Mechanically, the motor uses size 112 and a centering diameter of 130 mm for accurate mounting to machine plates and adapter faces. The centering shoulder helps align the motor shaft with couplings and driven components, which reduces mounting error during installation. The ED winding supports a nominal speed of 3000 rpm at rated current, which suits general servo applications that need stable mid-to-high operating speed. Heat is removed through natural convection, so the housing should remain exposed to free ambient air instead of being enclosed against nearby surfaces. Because the motor does not include a blocking brake, any load that must remain fixed after shutdown needs external holding hardware or drive-applied torque.

Electrical integration is handled through a power connection on connector on side A, which keeps cable routing near the preferred end of the housing in many machine layouts. That arrangement helps keep power leads clear of rotating machine members when the motor is mounted with the shaft facing the load. Speed feedback quality is listed as Standard, and the built-in tacho generator outputs 3 V/1000 rpm so the analog controller receives a linear speed signal. If an incremental or absolute encoder version is used, the same housing format can accept that feedback option without changing the basic motor envelope. The motor length code D gives the unit a longer active section than shorter lengths in the same frame, which helps support continuous operation and stable thermal behavior.
