Product Description:

The MAC063C-0-MS-3-C/095-B-0/S007 is an AC servo motor manufactured by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed for analog drives, it delivers controlled torque and speed to mechanisms such as indexing tables, packaging axes, and small gantries within automated cells. Its electromechanical design permits precise responses to current-loop commands from compatible drive amplifiers, supporting accurate positioning and speed regulation in established motion systems.

The motor’s rated speed reaches 3500 rpm, which is the upper continuous speed it can sustain when the drive supplies nominal current. A centering diameter of 95 mm seats the housing accurately on machine frames and keeps the shaft aligned with coupled loads. Heat is removed through natural convection, so no external fan or liquid-cooling circuit is required. Electrical power enters through a connector on side B, allowing the cable to be routed away from the feedback end and adjacent moving components. Internally, the stator uses winding code MS, which indicates the copper fill and number of turns associated with the motor’s voltage constant and current demand. These electrical characteristics allow the connected analog amplifier to supply suitable current throughout the normal operating range without compromising speed-loop response.

The motor has no blocking brake, so position holding after power removal must be provided by drive torque or an external clamp. Its feedback package combines tacho feedback with a second shaft end, providing an analog speed signal and an accessible end for an encoder or manual handwheel. The 063 frame designation indicates a moderate housing diameter that balances rotor inertia and peak torque for light to medium loads. During operation, the tacho generator outputs 1.5 V/1000 rpm, allowing the analog controller to regulate velocity from a proportional voltage signal. This feedback arrangement supports stable speed correction when the mechanical load changes during indexing, conveying, or positioning movements.
