Product Description:

The MAC025C-0-QS-2-E/040-A-0/S001 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. The unit functions as a rotary actuator in closed-loop positioning and velocity applications throughout automated assembly, material handling, and light machining cells. By converting electrical commands from analog drive controllers into controlled shaft movement, it forms the electromechanical link between the drive power stage and the mechanical load. Its compact frame and feedback arrangement support accurate speed regulation on small-inertia axes. This type of motor is well suited to machinery that requires responsive starts, stops, and speed changes without using a large motor package.

Heat is removed through natural convection, so the housing relies on ambient airflow without fans or liquid circuits. Shaft speed is monitored by built-in tacho feedback, which returns an analog voltage proportional to rpm for the drive’s velocity loop. The motor has a frame size of 025 and a motor length of C, giving it a compact envelope for tight installation spaces. Electrical power is delivered through a sealed connector on side A, which keeps the supply cabling parallel to the motor axis and helps simplify routing inside smaller machine enclosures. Because the cable exit follows the motor axis, the unit can fit more easily where nearby guards, slides, or mounting surfaces limit radial clearance.

The motor has no blocking brake, so external holding methods are required when vertical or overhung loads are present. The unit is categorized as a motor for analog drives, meaning its electrical interfaces match voltage and current commands from legacy analog control amplifiers rather than fieldbus-based digital inverters. This arrangement suits established motion systems that still rely on current and voltage command architecture. It also allows the motor to operate in applications where passive cooling and analog speed feedback are preferred over more complex digital communication methods.
