Product Description:

The MAC071A-0-HS-3-C/095-B-1 is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It is intended for analog drive systems where a velocity signal is required directly from the motor, making it useful for point-to-point and speed-regulated axes in automated production. Permanent magnets generate synchronous torque, while a built-in tachogenerator on the second shaft end supplies real-time speed feedback to analog controller hardware. This arrangement allows the motor and drive to operate together without requiring a separate external speed-sensing device.

The motor reaches a nominal speed of 2000 rpm, which supports continuous operation for matching gear ratios and drive amplifiers. Its winding code is HS, which identifies the electrical winding used for this motor. A centering diameter of 95 mm seats the stator precisely in machine frames so radial misalignment is minimized. Power is routed through a connector on side B, which helps keep the cable exit away from moving machine parts on side A. Heat produced in the stator is removed by natural convection, so no fan or liquid cooling circuit is required. This cooling method keeps the installation simple as long as surrounding airflow remains unobstructed.

A blocking brake is installed as standard and can hold up to 3 Nm when the axis is de-energized. The tachogenerator outputs 3 V/1000 rpm, giving the analog controller a proportional voltage for closed-loop speed regulation. Motor size code 071 corresponds to the frame diameter and mounting pattern used for this housing. The mechanical length designation A keeps overall mass low, which is useful for gantry heads or pivot arms where added inertia can reduce dynamic response. The installed brake can also help keep the axis in position during power-off stops.
