Product Description:

The MAC041A-0-FS-4-E/050-B-0/WI673LV/S006 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for closed-loop motion axes, it converts electrical command signals from analog drives into precise shaft rotation for positioning and speed regulation in assembly machines and handling modules. The design follows a brushless three-phase topology, generating continuous torque through permanent-magnet excitation while preserving the compact footprint required by space-constrained equipment. Its direct-coupled construction removes gear backlash and enables high repeatability when executing indexed moves in packaging lines or small gantry axes. The brushless layout also reduces wear because there are no commutator contacts, which supports consistent operation over long duty cycles.

The unit uses an FS winding, which sets coil resistance and current density for the matching drive output stage. The motor has a frame size of 041 and a motor length of A, giving it a compact housing for smaller axes. Heat is removed through natural convection, so the housing should be installed where free airflow is available. Power conductors connect through a connector on side B, which can simplify cable routing when the flange faces the machine frame. The motor has no blocking brake, so load holding during power loss must be provided by drive torque or an external clamp.

A dual-channel system supplies position and speed feedback, including tacho feedback for velocity control and an incremental encoder for position monitoring by the controller. As a motor for analog drives, the MAC041A integrates with legacy control systems that use tachometer voltage and incremental marker signals instead of fieldbus communication. This arrangement avoids extra signal-conversion hardware and helps maintain responsive closed-loop operation during continuous duty.
