Product Description:

The MAC071B-0-TS-2-C-095-B-0-S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for analog drives, so current-mode amplifiers supply the torque-producing current instead of fully digital regulators. In automated machinery, this motor provides closed-loop speed control and position holding for axes that require moderate torque and a base speed suited to gearboxes or direct coupling. Because it works with analog control hardware, the motor is suited to systems that rely on separate speed feedback rather than integrated digital regulation.

The mechanical interface uses a centering diameter of 95 mm, allowing repeatable location in a bell housing or mounting flange. Heat is removed through natural convection, so rated output must be observed when airflow is limited and no auxiliary fan is used. Rotor speed and velocity control are supported by tacho feedback, which lets the analog drive monitor motor speed continuously. The windings reach a nominal speed of 3000 rpm, giving the drive a common operating point for continuous service. The tachogenerator produces 3 V/1000 rpm, which provides a proportional speed signal for the control loop.

Power leads exit through a connector on side B, which keeps cabling on the same face as the machine junction box and can simplify routing in compact installations. The motor has no blocking brake, so holding torque during power-off must be provided externally when the axis must remain fixed. This arrangement leaves fewer components inside the housing and simplifies the external connection layout. Its frame size is 071, and winding code TS identifies the electrical characteristics used with compatible analog amplifiers. The intermediate B motor length provides a compact housing while maintaining the proportions associated with this frame.
