Product Description:

The Bosch Rexroth Indramat MAC093A-0-PS-4-C/110-B-1/WI520LV/S001 is an AC servo motor supplied in the MAC AC Servo Motors series. It serves as the prime mover in analog drive systems where a precision speed or position loop is executed directly inside the drive amplifier. By transforming the amplifier’s command voltages into tightly regulated mechanical output, the motor enables accurate indexing of transfer lines, tool changers, and packaging equipment. Integrated tachometer and encoder interfaces allow direct velocity and position feedback without ancillary transducers, which helps simplify installation in compact motion assemblies. This arrangement also allows the paired drive to react quickly to speed changes during starts, stops, and shifting load conditions.

The mechanical interface of the motor centers on a 110 mm pilot, ensuring concentric mounting to gearboxes or precision frames. Thermal management relies on natural convection, so airflow around the housing must remain unobstructed when the motor is loaded continuously. Frame designation 093 places the motor in a medium power class, and the magnetic and mechanical design supports a base speed of 3000 rpm that couples directly to ball-screw or pulley ratios used on high-cycle machines. An internal tachogenerator delivers 3 V/1000 rpm, providing a proportional velocity signal that analog drives use for closed-loop regulation. The combination of pilot fit, cooling method, and speed capability suits motion axes that need steady tracking and repeatable response through continuous production cycles.

Electrical behavior is linked to the winding designation PS, a code used for compatibility with MAC servo amplifiers. Stack length A keeps the rotor short, helping the axis accelerate rapidly when the standard blocking brake is released. Power conductors terminate through a connector on side B, an arrangement that prevents cable loops from crossing moving slideways and supports cleaner routing in confined machine spaces. The position loop can be closed with an incremental encoder mounted in the standard flange, and the feedback package supplies both fine positional data and real-time speed information to legacy control cards. This layout supports analog control systems that still require accurate motion feedback from a compact motor package.
