Product Description:

Bosch Rexroth Indramat manufactures the MAC041A-0-IS-2-E/050-A-0 as part of the MAC AC Servo Motors series. This brushless synchronous unit is intended for closed-loop positioning duties in automated assembly lines, pick-and-place modules, and other precision axes where consistent torque, rapid acceleration, and repeatable settling times are required. Integrated sensors provide velocity feedback to the drive, allowing the controller to regulate stator excitation and hold commanded motion profiles under moderate load fluctuations. Because the drive receives continuous speed information from the motor, it can correct small load-related deviations quickly during short indexing and positioning cycles.

The unit is supplied without a blocking brake, so any static holding function must be provided by an external mechanical lock or by continuously energized drive torque. Heat generated in the windings is removed through natural convection, eliminating the need for auxiliary fans and simplifying cabinet airflow design. Rotor speed is monitored through built-in tacho feedback, giving the drive a proportional voltage signal that supports analog velocity loops. Power is delivered through a sealed connector mounted on side A of the stator housing, which simplifies cable routing when the motor is flange-mounted with the shaft facing the work area. The sealed connection keeps the electrical interface enclosed without requiring a separate terminal box.

The motor uses the 041 build, which pairs a compact stack height with moderate continuous torque output. Within the same frame family, the size A stator diameter helps keep mass low for quick inertia matching in small gantry or indexing tables. The documented motor length places the unit within the short housing range used for compact axes. Its classification as a motor for analog drives confirms compatibility with voltage-controlled servo amplifiers that rely on linear current stages. That arrangement suits applications where moving-axis mass and installation space must both remain limited.
