Product Description:

The MAC025C-0-QS-4-E/040-A-0/WI651LV is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. In automated cells, it couples with an analog drive amplifier to generate precise shaft torque and velocity, turning electrical control signals into repeatable mechanical motion for indexing tables, feed axes, and material-handling fixtures. It belongs to the medium-frame portion of the series and is used where compact dimensions, moderate inertia, and integrated electronic feedback are required for coordinated multi-axis motion.

With a frame size of size C, the unit uses a stator diameter that balances magnetic flux against installation space, while the stack depth marked 025 supports continuous torque without unnecessary mass. Heat released by the windings is removed through natural convection, so no external blower or liquid manifold is required, and the mounting position must permit free airflow around the housing fins. The three-phase power leads exit on side A through a keyed circular connector, which simplifies cable routing in cabinets where multiple motors are installed close together. Rotor position is reported to the drive by an integrated incremental encoder, providing the high-resolution quadrature signals needed for tight velocity loops.

Because there is no blocking brake, the application must rely on drive current or an external clamp to hold static loads when power is removed. The feedback harness also carries tachogenerator and encoder feedback, allowing the drive to use speed and position signals during ramping. As a motor for analog drives, its interface remains compatible with ±10 V command references and sinusoidal commutation used by earlier MAC controllers. The motor is intended for repeated start-stop duty when ambient conditions stay within the permitted operating range.
