Product Description:

The MAC041A-0-FS-2-E/050-A-0/S007 is a compact AC servo motor built by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. As a motor for closed-loop positioning and speed control, it converts electrical command signals from analog drive controllers into precise shaft torque for automated machinery, transfer lines, and small handling axes. Its designation as a motor for analog drives means the command interface expects ±10 V speed or torque reference signals rather than digital fieldbus communication. This makes the unit suitable for compact motion axes that need accurate speed response and repeatable positioning.

This unit uses winding code FS, which indicates the stator’s electrical resistance and inductance so the matched drive can supply the proper current without magnetic saturation. Frame designation A indicates the smallest housing cross-section in the MAC family, which reduces installed weight and inertia for fast acceleration. The mechanical stack depth corresponds to length code 041, which supports continuous torque while keeping the motor short enough for tight machine envelopes. Heat produced in the windings is removed through natural convection, eliminating the need for external air or liquid cooling hardware. This cooling method keeps the motor layout simple and avoids added blower or coolant connections on the machine.

For velocity feedback, the motor is equipped with tacho feedback; the built-in DC tacho generator supplies an analog voltage proportional to speed, allowing the drive to regulate rpm in real time. This feedback method supports stable speed monitoring across the operating range used by compatible analog controllers. The motor has no blocking brake, so applications that require static holding torque must rely on drive current or an external brake module. Power is supplied through a connector on side A, which can simplify cable routing when the motor is mounted with the flange facing the machine frame.
