Product Description:

The MAC071A-0-ES-4-C/095-B-0/WA612XX/S01 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for analog drive systems that require closed-loop speed and position control in packaging machines, material-handling axes, and similar automation equipment. By combining motor operation with integrated feedback support, the unit supplies continuous speed information to the controller so commanded motion remains stable during load changes, start-stop cycles, and routine positioning tasks. That arrangement supports repeatable motion in machines that need smooth speed regulation throughout normal production.

This model has a centering diameter of 95 mm, providing a reference surface for precise shaft alignment in gearboxes or mounting flanges. Heat is removed by natural convection, which eliminates external fans and keeps installation simpler in enclosed cabinets. Under rated conditions, the rotor can reach 4000 rpm, giving the motor a fast operating range for indexing, tracking, and other high-response motion tasks. The three-phase power leads exit through a connector on side B, which helps keep cabling clear of nearby moving machine parts. The built-in tacho generator outputs 1.5 V/1000 rpm, giving analog regulators a linear signal for real-time speed monitoring.

The motor is supplied with no blocking brake, so vertical or suspended loads must be held by external hardware when power is removed. The motor uses frame code 071, which places it in a MAC family size suited to medium-power servo applications. Winding code ES identifies the electrical winding arrangement used by compatible drive systems and matches the motor’s intended operating characteristics. Housing length code A keeps the overall motor depth short, which helps when mounting space behind the machine frame is limited. This shorter housing can also be useful where adjacent components leave little rear clearance.
