Product Description:

The MAC063A-0-ES-2-C/095-B-0/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drive systems, it converts commanded current into precise torque and speed for machine axes, conveyors, and pick-and-place actuators used in industrial automation. When connected to an external power amplifier, the permanent-magnet motor provides closed-loop motion control for applications that require compact and responsive rotary power.

With a frame classified as size 063, the motor uses length A to balance torque density and overall mass for compact equipment layouts. The centering pilot on the flange measures 95 mm, providing the reference surface for concentric mounting to gearboxes or machine frames. Its stator carries the ES winding code, which indicates resistance and inductance values that allow the companion amplifier to regulate the current loops. A nominal speed of 3500 rpm lets the shaft deliver moderate velocity while maintaining stable commutation. Heat generated during operation is removed through natural convection, eliminating the need for forced-air accessories and simplifying installation in compact machinery.

Rotor speed information is supplied through tacho feedback, which uses a DC tachogenerator to provide the analog drive with voltage proportional to shaft speed. The signal is calibrated at 1.5 V/1000 rpm, matching the standard tacho quality rating and providing predictable resolution for velocity control loops built from discrete components. Power reaches the stator through a connector on side B, directing cabling away from the motor face to keep access to the mounting area clear. The motor has no blocking brake, so vertical or high-inertia axes must rely on an external clamp or drive-supplied holding torque when motion stops. If the system is de-energized, the external holding device must secure the load because the motor cannot generate holding torque without electrical power.
