Product Description:
The MAC071B-0-TS-3-C/095-B-1 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it delivers closed-loop speed and position control for axes used in packaging, printing, material-handling equipment, and similar production machines. The unit includes a blocking brake for load holding, and its built-in tachogenerator supplies velocity feedback to the drive amplifier, allowing precise regulation during acceleration, constant-speed operation, or controlled deceleration.
During standstill, the brake applies 3 Nm of torque to lock the shaft. A centering diameter of 95 mm aligns the flange with machine housings for repeatable installation accuracy across standard machine faces. Internal losses are carried away by natural convection, eliminating the need for a fan and reducing maintenance points. The rotor can maintain a continuous speed of 3000 rpm, making it suitable for medium-inertia spindles and feed screws. To close the velocity loop, the tachogenerator outputs 3 V/1000 rpm; this linear voltage allows the analog controller to track speed changes with minimal phase lag and stable response during normal operation.
The housing dimensions correspond to frame size 071 and length code B, giving a compact overall length while preserving thermal mass for continuous duty. Power is supplied through a connector on side B, which keeps cable bends shallow when the motor is mounted against panels or machine structures. Electrical characteristics are set by winding code TS, matching resistance and inductance to analog amplifiers that can deliver rated current without saturation. The motor also has a second shaft end, so an auxiliary encoder, pulley, or manual hand wheel can be coupled directly for additional sensing or mechanical linkage without altering the primary drivetrain.
