Product Description:

The MAC071A-0-OS-2-F/095-A-1 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it supplies controlled torque and speed to automated machinery such as pick-and-place units, indexing tables, and material-handling axes. Integrated feedback allows the connected amplifier to regulate motion during changing loads and repeated start-stop cycles. A built-in blocking brake keeps the shaft fixed when power is removed, allowing the motor to hold loads securely during idle states or emergency stops.

The motor’s nominal speed reaches 3000 rpm, giving a balance between rapid cycle times and manageable drive currents in general automation service. This speed range suits axes that need responsive motion without requiring a large motor frame. With frame size 071, the motor uses a stator diameter and coil geometry suited to this housing size, which supports mounting compatibility within the series. A centering diameter of 95 mm aligns the housing precisely on machine adapter plates, helping maintain concentricity for couplings or pulleys. The blocking brake develops 3 Nm of holding torque for light to moderate inertial loads. Heat is removed by natural convection, so no external fan or liquid cooling circuit is required.

Electrical power reaches the stator through a connector on side A, which can simplify cable routing inside compact enclosures and help avoid unnecessary cable bends near the motor body. Winding code OS identifies the electrical characteristics matched to compatible analog servo amplifiers in the same product generation. For velocity feedback, a mechanically coupled tacho generator produces 3 V/1000 rpm, allowing the drive to monitor speed with a linear signal across the operating range. The motor is delivered with integrated tacho feedback, which supports smooth low-speed regulation and stable response during changes in load. This feedback arrangement is useful in applications where steady speed control is required during frequent acceleration and deceleration.
