Product Description:

The MAC025C-0-QS-2-E/040-A-1 is a brushless AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for pick-and-place arms, indexing tables, and material-feed modules where commanded current from a matching amplifier is converted into repeatable rotary motion. Because the unit works with analog velocity and torque loops, it fits systems that continue to use earlier control hardware while still requiring stable speed regulation and accurate axis response. This makes it suitable for packaging, handling, and light assembly equipment that depends on predictable motor response during frequent starts and stops.

The housing uses natural convection cooling, so heat leaves the stator through surface fins and surrounding air without fans or liquid lines. Integrated tacho feedback supplies a voltage proportional to shaft speed, giving the controller a real-time signal for closed-loop velocity correction during changing loads. The feedback signal helps the drive hold commanded speed more steadily when the load changes through the cycle. The motor has a size C frame and a 025 length, which provide moderate torque capacity with low rotor inertia for fast acceleration. Electrical power enters through a connector on side A, keeping the cable exit parallel to the motor axis and leaving the mounting face clear.

A standard blocking brake engages when drive current is removed, helping prevent load drift on vertical or inclined axes. When the axis is idle, the brake can hold position without relying only on motor torque from the amplifier. The unit is a motor for analog drives, so its electrical behavior matches the signal and brake-control requirements used by earlier MAC amplifiers. This makes the motor suitable for existing analog-control machinery that requires compatible feedback behavior and predictable operation through repeated starts and stops.
