Product Description:

The MAC071C-0-GS-4-C/095-B-0/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Built for analog drives, it delivers closed-loop torque and velocity control for repeatable acceleration, deceleration, and steady-speed motion in packaging, machine tool, and material-handling axes used in automated equipment. The unit is supplied without a blocking brake, so external mechanical restraint is required when the shaft must remain stationary after power-down. This makes it suitable for axes that rely on drive torque during operation but need separate holding force at rest.

At a nominal speed of 6000 rpm, the rotor is optimized for fast cycle duties while maintaining the magnetic profile associated with the GS winding code. Shaft alignment during installation is simplified by a centering pilot of 95 mm, which mates with standard machine adapters. Thermal management depends on natural convection; therefore, the housing fins must stay unobstructed so heat can rise away from the stator without auxiliary blowers. Power conductors enter through a connector on side B, keeping the cable bundle clear of the driven load and shortening the route to panel-mounted analog drives.

The motor occupies the 071 frame class and follows the intermediate C length code, balancing torque output against footprint for mid-range axes. Position and velocity signals are taken from an incremental encoder mounted with the series standard interface; its companion tachogenerator produces 1.5 V/1000 rpm, and the resulting standard tacho quality waveform is suited to analog velocity loops that demand linear speed feedback. The encoder and tachogenerator provide the feedback channels needed for positioning and stable speed regulation in analog systems. Because the feedback and power connectors are separated, routing noise into the control cabinet is minimized during operation.
