Product Description:

The MAC071B-0-TS-3-C/095-B-2/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for positioning and velocity-regulated stations where analog drive amplifiers control motor current and speed. The motor converts amplifier commands into mechanical rotation for gear stages, ball screws, timing belts, and other transmission components used in automated assembly cells and material-handling equipment. Integrated speed feedback allows the paired analog regulator to monitor rotor velocity and correct deviations caused by changing loads. Its compact design supports installation on machine axes that require controlled acceleration, repeatable motion, and dependable holding capability.

The motor uses frame size 071, providing a compact form that fits within confined machine frames while accommodating the thermal load associated with winding code TS. A heavy-duty blocking brake rated at 6.5 Nm holds the shaft when power is removed, helping prevent vertical or suspended loads from drifting. The rotor operates at a nominal speed of 3000 rpm, making the motor suitable for motion profiles that require responsive acceleration and steady speed regulation. A centering pilot measuring 95 mm locates the housing accurately on reducer flanges or mounting plates and helps minimize radial alignment error. The B-length stator provides the active motor length used for this configuration, while the brake supports secure load retention after controlled deceleration.

Heat is dissipated through natural convection, so the motor does not require an auxiliary blower or liquid-cooling circuit. Adequate airflow around the housing allows heat from the stator windings to pass into the surrounding air during operation. A tacho generator on the second shaft end produces 3 V/1000 rpm, enabling the analog regulator to compare actual speed with the reference signal and correct errors in real time. Power enters through a connector on side B, keeping the cable route away from the driven-load side and providing convenient access to the connection point. Standard tacho quality supports stable velocity feedback during acceleration, constant-speed operation, and deceleration. The side-B connector orientation also helps prevent interference between the motor cable and couplings attached to the output shaft.
