Product Description:

The MAC063A-0-ES-2-C/095-B-1 is a brushless AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, it converts small control voltages into regulated torque and speed for machine tools, conveyors, and assembly stations. An integrated tachogenerator supplies real-time velocity data so the drive can close its servo loop and maintain setpoints as the mechanical load changes. This arrangement supports stable speed control in axes that need repeatable motion without a separate feedback package. Because the motor is brushless, there are no commutator brushes to wear during normal servo duty, which helps support consistent response over repeated cycles.

The motor uses frame size 063, which supports installations with limited space while still providing useful output for medium-duty axes. A centering pilot of 95 mm aligns the housing with mounting flanges or gearboxes to help reduce radial misalignment during assembly. Nominal shaft speed reaches 3500 rpm, allowing fast indexing when paired with suitable gearing. A fitted brake provides 3 Nm of holding torque, which helps keep vertical or rotary loads in place after supply power is removed. The short A-length rotor reduces inertia, helping the axis respond quickly to changes in command speed or position. This layout fits compact mounts where the motor must accelerate quickly without requiring a larger frame.

Cooling relies on natural convection, so no fan is required and air can move freely around the housing. Passive cooling also keeps the outside shape simple because no auxiliary blower housing is needed. The motor uses winding code ES, and the matching analog drive is selected to suit its electrical characteristics. Tachofeedback is proportional at 1.5 V/1000 rpm, giving the controller a direct speed signal for regulation at low and moderate operating speeds. Power conductors exit through a connector on side B, which can simplify cable routing when the opposite face is reserved for mounting access or nearby machine parts.
