Product Description:

The MAC112D-0-ED-4-C/130-A-0-W1520LV/S00 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it converts voltage commands into precise shaft motion for automated machinery. The design couples a permanent-magnet rotor with integrated speed feedback, allowing closed-loop control of packaging lines, handling modules, and other industrial axes that require repeatable torque. This arrangement lets the paired amplifier monitor motor behavior continuously and correct speed changes caused by shifting load conditions.

The centering diameter of 130 mm seats the flange precisely on gearboxes and mounting plates, helping keep radial runout low. Heat is removed through natural convection, so the installation must leave clear air space around the frame instead of relying on auxiliary fans. Under rated conditions, the shaft reaches 3000 rpm, which suits analog drive operation in medium-inertia loads. Power conductors terminate at a connector on side A, which simplifies cable routing in compact cabinets. The internal tacho generator delivers 3 V/1000 rpm, providing a linear voltage signal for speed regulation. Standard tacho quality and encoder feedback complete the feedback path.

The frame size 112 gives the motor a larger magnetic cross-section than smaller MAC units, while the extended D length adds stack iron to raise continuous torque without increasing current. Winding code ED indicates resistance and inductance values that match legacy voltage-controlled amplifiers and help avoid saturation during dynamic cycles. The motor has no blocking brake, so vertical or safety-critical axes need an external holding method when power is removed. When a load must remain fixed at standstill, the holding function has to be provided by the machine design or by the drive system.
