Product Description:

The MAC071A-0-HS-4-C/095-B-0/519LX belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is supplied as a motor for analog drives, where it converts current-controlled commands into precise shaft rotation for industrial automation tasks. Within the series lineup, this model serves applications that rely on the motor’s tacho-based speed feedback to keep velocity errors low while running closed-loop position or speed regulators.

The centering pilot is machined to 95 mm, giving a fixed reference diameter for aligning the flange to a machine frame. Heat is dissipated by natural convection, so no external blower or liquid circuit is required and mounting can remain compact. Its windings follow the HS code, a selection that indicates copper fill and impedance values suited to medium-voltage analog amplifiers. At the rated point, the shaft reaches 2000 rpm, providing a balance between torque output and mechanical life in indexing tables or feed axes. A built-in tacho generator produces 3 V/1000 rpm, and with standard tacho quality, the speed signal stays linear enough for proportional control loops. Incremental or absolute encoder options can be fitted alongside the tacho so that digital motion controllers may also obtain position information without additional adapters.

The motor has no blocking brake, so any vertical axis using this motor must hold load torque through drive current or a separate mechanical lock. Power conductors exit through a connector on side B, keeping cable routing on the non-drive end and freeing the shaft side for couplings or pulleys. Overall length follows motor length A, resulting in a compact body that pairs with motor size 071. The natural-convection housing and side-B connector arrangement keep the installation compact while matching the analog drive layout used by this motor type.
