Product Description:

The MAC071B-0-TS-3-C/095-B-0 is a three-phase AC servo motor produced by Bosch Rexroth Indramat for use with analog velocity and current loops. It belongs to the MAC AC Servo Motors series and is used in positioning tables, handling axes, and other automation modules that require stable speed regulation. The motor converts drive commands into mechanical rotation while providing the continuous response expected in legacy analog motion systems. Its housing and mounting arrangement suit machine designs that need a compact servo motor with integrated speed feedback and straightforward installation.

Mechanical alignment is aided by a centering pilot of 95 mm, which helps the motor seat concentrically in the machine housing. Heat is removed through natural convection, so the unit operates without an external blower or liquid cooling circuit when surrounding airflow is adequate. Under rated conditions, the rotor turns at 3000 rpm, a speed that suits common gearbox ratios and supports stable feedback generation. The TS winding code identifies the electrical winding used with the designated analog amplifier family. Power enters through a connector on side B, which can simplify cable routing when the driven load or coupling is located at the opposite end of the motor.

Overall dimensions correspond to frame size 071, so the motor fits machine layouts intended for this housing size. The built-in DC tachogenerator produces 3 V/1000 rpm, giving the connected drive continuous speed feedback during operation. The motor uses tacho feedback with a second shaft end, allowing an auxiliary encoder or mechanical coupling to share the same rotation when the application requires it. Because the motor is supplied without a blocking brake, load holding during power-off must be handled by an external clamp or by controlled drive torque when the application permits. This arrangement suits analog systems that need direct feedback, passive cooling, and a compact motor for continuous industrial duty.
