Product Description:

The MAC063A-0-RS-2-C/095-B-1 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Built as a motor for analog drives, it converts drive controller commands into rotary motion for positioning axes, feeders, and compact handling units in industrial automation lines. Its compact frame and integrated sensor enable closed-loop speed regulation, making it suitable for applications that need responsive motion in a small installation space. The model also incorporates tacho feedback so the drive can monitor actual shaft speed without an external encoder. This arrangement is useful in machines that need precise speed control without adding extra feedback hardware. Because the feedback device is built into the motor, the installation remains compact and avoids the need for a separate speed sensor assembly.

At its nominal operating point, the rotor reaches 6000 rpm, so the motor can support high shaft speed in compact axis applications. A blocking brake is fitted and delivers 3 Nm of holding torque, which helps keep light loads stationary when power is removed. The housing centers on a 95 mm pilot for accurate alignment to gearboxes or mounting plates. Heat is removed through natural convection, so no external fan or liquid circuit is required when ambient airflow is available. Power leads exit through a connector on side B, helping route cables away from the driven shaft inside tight machine spaces.

The electrical winding identified by code RS pairs the motor with standard MAC analog drives and corresponds to the motor's electrical characteristics. Within this winding, the built-in tacho generator outputs 1.5 V/1000 rpm, giving the controller a proportional feedback signal across the operating range. Frame size 063 and body length A keep overall mass low while still providing the rotor inertia needed for smooth velocity regulation. The tacho signal supports analog amplifiers that rely on continuous speed feedback for stable control under changing load conditions. The short housing also helps the motor fit into compact machine sections where axial mounting space is limited.
