Product Description:

The MAC063A-0ES-2-C/095-A-1 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified for analog drives, it supplies rotational power for coordinate axes, tool heads, and conveyors in automated equipment. Position and speed are monitored by an integrated tacho feedback device, while motion commands reach the motor through a power connector on side A of the housing. It is intended for machines that require accurate speed regulation without a separate feedback assembly. The motor uses natural convection for heat removal and fits a machine flange with a centering diameter of 95 mm, which supports the compact size 063, length A construction.

The electromagnetic profile starts with a continuous stall torque of 0.8 Nm, produced whenever the rotor is energized but not turning, and it requires 2.2 A at that condition. Under regular loading, the shaft can rotate at a nominal speed of 3500 rpm, which suits medium-duty positioning tasks. Torque output rises in proportion to current, and the torque constant is 0.370 Nm/A so the drive can relate phase current to motor torque. A holding brake that operates on DC 24 V supplies 3.0 Nm of mechanical locking torque when power is removed. The attached standard tacho returns 1.5 V per 1000 rpm for analog speed control.

For short transients, the winding can accept 12 A, allowing rapid acceleration before thermal limits are reached. Electrical response is influenced by a winding inductance of 9.1 mH and a resistance of 9.6 ohms, which affect current rise and copper losses in the stator. That electrical behavior is important during frequent starts, stops, and reversals. Heat from intermittent peaks dissipates slowly, as shown by a thermal time constant of 30 min, so duty cycles should allow time for the motor to cool between overload events. The side-mounted connector and standard tacho arrangement support use in legacy analog drive cabinets while preserving convection-cooled operation.
