Product Description:

The MAC063A-0-ES-4-C/095-A-0/AM144SG is an AC servo motor produced by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. It is intended for analog drive amplifiers where closed-loop velocity and position control are required in packaging machines, handling systems, and light machining centers. Integrated feedback allows the drive electronics to monitor shaft movement without external sensors. A blocking brake is not included, so holding torque must be provided by the drive or by external mechanics during power-off conditions.

The machined mounting face features a centering diameter of 95 mm, which aligns the stator housing with gearboxes or adapters and helps maintain accurate installation. At rated excitation, the rotor reaches 3500 rpm. Heat generated by copper losses is removed through natural convection, eliminating the need for forced air or liquid cooling hardware and simplifying cabinet design. For position verification, the unit uses an integrated absolute encoder that provides multi-turn data to the controller, supporting a homing-free startup after power interruptions. A built-in tacho generator produces 1.5 V/1000 rpm, giving the analog velocity loop a proportional signal that scales directly with shaft speed.

The frame code of 063 indicates a compact stator diameter suited to applications with limited mounting space, while motor length code A represents the shortest magnetic stack available in the platform. The shorter stack helps reduce inertia and axial space, which is useful in tightly arranged machine layouts. Power conductors exit through a keyed connector on side A, placing the cabling parallel to the load axis and easing routing inside tight enclosures. Electromagnetic behavior is governed by winding code ES, which corresponds to resistance, inductance, and thermal rise characteristics compatible with MAC analog drives.
