Product Description:

The MAC041C-0-LS-3-E/050-B-0/S001 is a brushless AC servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. It is configured for analog drives, making it suitable for velocity or position loops that rely on ±10 V command stages rather than digital fieldbus control. In automated machinery, the unit converts drive commands into rotational motion so that slide tables, feeders, or indexing devices achieve repeatable speed and position accuracy. This type of motor is commonly used in systems where a separate amplifier handles current regulation and closed-loop axis control.

The motor dissipates its internal heat by natural convection, so enclosure airflow must remain unobstructed when it is mounted inside a cabinet. Rotor position and speed are reported by integrated tacho feedback, and a second shaft end can be used for a mechanical tachometer or another auxiliary connection. The motor has a motor size C frame and an overall length 041, allowing it to fit medium-power axes where a smaller housing would be undersized. Power conductors exit through a connector on side B, which can simplify cable routing when the drive train occupies the opposite side of the motor. The passive cooling arrangement also avoids the need for a separate motor-mounted fan.

The motor is supplied with no blocking brake, so the shaft will not hold position when power is removed. On vertical or suspended axes, an external holding device is needed whenever the load must remain fixed after shutdown. The LS winding matches analog MAC drives configured for 50 V class outputs, keeping current ripple within the limits of their linear amplifiers. With this winding and cooling method, the motor can deliver continuous torque as long as ambient conditions allow convection to remove heat. Feedback signals and mounting codes follow the conventions used across the MAC product line, which supports consistent integration with related drive components.
