Product Description:

The MAC112D-0-ED-4-C/130-A-0/WI520LX AC servo motor is produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for analog drive loops that demand accurate speed and position control across automated packaging, material-handling, and general machinery platforms. By translating regulated electrical input from a drive amplifier into controlled rotation, the unit provides the mechanical work required for coordinated motion inside an industrial automation cell. This motor is suited to applications where the amplifier must maintain stable response during repeated starts, stops, and speed changes.

The motor uses a centering pilot of 130 mm, allowing precise alignment with gearboxes and fixtures. Heat is removed by natural convection, so housing fins dissipate losses without fans or liquid cooling. Under rated excitation, the rotor reaches 3000 rpm, which gives the drive a nominal operating speed for steady running and axis setup. Power conductors exit through a connector on side A, which routes cabling toward the machine frame. For velocity feedback to analog regulators, the integrated tachogenerator supplies 3 V/1000 rpm, and the control card reads that proportional signal directly.

The motor uses the ED winding, which provides resistance and inductance values compatible with legacy amplifiers. The unit has no blocking brake, so holding torque during shutdown must come from external clamps or drive current. The housing corresponds to size 112, and the D length gives shaft dimensions suited for moderate inertia loads. Position data comes from an incremental encoder mounted in the standard location, and that feedback supports closed-loop speed and position monitoring during operation. The motor also uses standard-quality tacho feedback, allowing the drive to process a stable velocity signal without additional signal conditioning.
