Product Description:

The MAC071A-0-HS-4-C/095-B-1 is an AC servo motor built by Bosch Rexroth Indramat and integrated into the MAC AC Servo Motors series. Intended for analog drive systems, it converts electrical commands from legacy controllers into controlled mechanical rotation for machine tools, printing presses, and handling units. This self-cooled unit incorporates a blocking brake for load holding during power-off conditions and relies on embedded tachometer feedback to supply real-time speed information to the drive amplifier. The combination of onboard braking and speed feedback supports stable axis control without requiring separate external devices for those functions.

With a frame designation of 071, the motor fits mounting interfaces standardized for this stator diameter, while a centering diameter of 95 mm ensures precise alignment against mating flanges. Its nominal shaft speed is 2000 rpm, which is the rated operating speed at nominal voltage and frequency. The blocking brake applies 3 Nm of static torque to hold moderate loads while the axis is at rest. Heat is removed solely by natural convection, so no auxiliary fan or separate cooling connection is required. The standard tachometer provides a proportional feedback signal of 3 V per 1000 rpm, which the analog drive uses for closed-loop speed regulation.

Electrical performance is linked to the winding code HS, which corresponds to the resistance and inductance values expected by the drive. The motor has length code A, which gives it a compact housing depth for installations with limited axial space. The power leads exit through a connector on side B, which can simplify cable routing when the motor is mounted close to a machine wall or vertical bulkhead. Additional feedback can be provided by an incremental or absolute encoder with tachometer feedback, allowing the control system to receive speed information together with position data when the application requires more than tachometer-based regulation alone.
