Product Description:

The MAC041C-0-LS-3-E/050-B-0/S007 is a servo motor engineered by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. Built for use with analog drive controllers in industrial automation, the motor transforms command voltages into tightly regulated torque and speed. This supports positioning and velocity loops on compact mechanical axes where repeatable motion is required, including small handling units, feed assemblies, and other machines that rely on stable analog speed control.

It relies on passive heat dissipation through natural convection, so no external fans or liquid circuits are needed during continuous operation. The electromagnetic package uses size C, while the rotor-stack depth follows the 041 length code; together these dimensions set the continuous torque capability and mounting interface. An LS stator winding is fitted, matching the voltage constants and current ratings expected by analog amplifiers in the 40 mm class. Power enters the housing through a screened connector on side B, which permits cable routing along the machine frame and helps reduce electromagnetic noise toward feedback leads. For stop-hold situations, the unit is supplied without a blocking brake, so external clamping or motor torque must maintain position when power is removed.

The embedded tacho feedback element mounted on the rear shaft provides a proportional voltage signal that analog controllers use for closed-loop speed regulation. A machined second shaft end is available on the opposite side for coupling handwheels, encoders, or load sensors without altering the primary drive line. Because the extra shaft interface is separate from the main output, accessory devices can be attached without changing the basic drive connection. The feedback channel helps the controller correct speed deviations as load conditions change during operation.
