Product Description:

The MAC041A-0-FS-4-E/050-A-0/WI670LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. The unit is intended for analog drive systems that require closed-loop velocity or position regulation in automated machinery, converting drive commands into precise shaft movement for feeders, positioning slides, and similar industrial axes. Integrated feedback allows the paired amplifier to monitor shaft motion continuously, which supports stable response during speed changes and positioning moves.

The unit relies on natural convection to remove heat from the stator, so installation must allow air to flow around the housing. It is supplied without a blocking brake, so any static holding duty must be handled by the mechanical transmission or an external brake. Power conductors reach the windings through a connector on side A, which helps align cabling with adjacent drives. The FS winding code sets the resistance, inductance, and torque constant values used by compatible drive hardware. The size code 041 gives the motor a short form factor that lowers inertia while still supporting steady torque for light to medium loads.

The motor has frame size A, which matches smaller gear stages or direct-drive couplings where compact installation space is important. For speed supervision, the motor includes tacho feedback with incremental or absolute encoder capability, allowing legacy analog velocity loops to work alongside position capture when the proper decoder electronics are used. The specific sensing element is an incremental encoder with standard mounting, which provides 1 Vpp signals for common servo drive interfaces without custom brackets. These features identify the unit as a motor for analog drives, so it can be used where predictable response and familiar interface behavior are required.
