Product Description:

The MAC063A-0-RS-2-C/095-A-0/S007 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts current-loop commands from an analog amplifier into precise shaft rotation for automated pick-and-place units, indexing tables, and light conveyor sections. The unit is supplied without a blocking brake, so external clamping devices or continuous drive torque must hold a load when power is removed.

The motor features a centering diameter of 95 mm, allowing repeatable alignment with gearboxes and flange plates. Heat is dissipated by natural convection, eliminating the need for forced air or liquid circuits. Rotor position and speed are reported through tacho feedback, which produces a proportional voltage for drive regulation. Under rated excitation, the shaft can reach 6000 rpm, providing fast cycle times in small mechanical assemblies. Power conductors exit through a connector on side A, which simplifies wiring when the motor is mounted with the flange facing forward. The motor has an A length, so the housing remains short while still accommodating the winding package.

The feedback circuit uses standard tacho quality, making it suitable for general-purpose velocity loops where high linearity is not mandatory. The tachogenerator delivers 1.5 V/1000 rpm, which the drive card scales directly for speed regulation. The frame designation of 063 indicates the stator diameter and suits compact machines with limited space behind the load. The electromagnetic layout uses winding code RS, which establishes the current constant and back-EMF profile used by matching MAC analog controllers. This winding arrangement allows the controller to regulate motor current in accordance with the electrical characteristics of the stator. The motor can therefore operate within its thermal limits while relying on passive heat dissipation through the housing.
