Product Description:

The MAC041B-0-BS-4-E/050-B-0/WI671LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for use with analog drive controllers, the unit provides precise shaft rotation for closed-loop motion axes in packaging lines, pick-and-place stations, and similar automation equipment. Electrical power is converted into mechanical output through a permanent-magnet rotor and stator winding assembly. When the drive compares commanded and measured values, the motor can respond smoothly during starts, speed changes, and short positioning moves.

The motor relies on natural convection to remove heat, so installation must allow unobstructed airflow around the housing. Its frame uses Size B construction with a 041 motor length, which keeps the axial dimensions moderate for tight machine compartments. Supply leads are routed through a connector on side B, orienting the cable away from the load end and simplifying cabinet wiring near guards, couplings, and machine panels. The integrated incremental encoder with standard mounting delivers 1 Vpp signals for fine speed control, and the drive can also use tacho feedback for velocity monitoring during operation. This arrangement gives the controller a consistent feedback source without requiring forced cooling or external adapters.

Mechanical holding force is not provided because the unit is supplied without a blocking brake, so vertical or suspended axes must secure the load through external means when power is removed. The motor is classified as a motor for analog drives, allowing it to work with legacy command modules that output ±10 V speed or torque references. This makes it suitable for existing systems that still use analog motion commands instead of newer digital control networks. The compact frame and non-load-side cable routing help the motor fit into installations where space is limited and clear airflow around the housing must be maintained.
