Product Description:

The MAC041C-0-LS-4-E/050-B-0/WI651LV is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for motion control in machine tools, packaging stations, and general handling axes, the unit converts electrical power into tightly regulated rotary torque and speed that an analog drive can modulate. Its compact frame and integrated feedback support precise axis positioning, making it a suitable choice where low inertia and fast acceleration are required.

Thermal management relies on natural convection, so heat leaves the housing through surface radiation and ambient airflow without auxiliary fans. The mechanical envelope corresponds to the frame designation C, giving a mid-sized stator diameter that balances torque density against weight. The axial stack depth is coded as 041, which indicates the active iron and copper volume available for continuous torque. Power conductors exit through a connector on side B, simplifying cable routes when the motor is mounted with the shaft facing the machine. Electromagnetic characteristics follow winding code LS, which sets the resistance and inductance values recognized by the companion analog controller.

Position monitoring is handled through tachofeedback with an incremental or absolute encoder, giving the drive either velocity-proportional signals or discrete position data depending on the installed transducer. For applications that only need pulse feedback, the secondary option uses an incremental encoder with standard mounting, allowing replacement with commonly available sensor heads. The motor has no shaft-locking brake, so vertical loads must be secured by external clamping or by keeping the servo energized when stationary. Because it is a motor for analog drives, command interfaces use voltage or current loops rather than digital fieldbuses, which supports integration into legacy control cabinets.
