Product Description:

The MAC041B-0-QS-2-E/050-A-0/S001 is a compact AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It converts current commands from a compatible servo amplifier into controlled torque and rotary speed for positioning, indexing, and contouring axes. Its compact housing is suitable for automated machinery where installation space is limited and repeatable motion is required. Integrated speed feedback allows the connected amplifier to correct velocity changes caused by varying loads during operation.

The motor has a frame size of 041 and a frame length of B, providing a compact electromagnetic assembly with low rotating inertia. Power conductors exit through a connector on side A, allowing the cable to be routed along the selected side of the motor without crossing nearby moving components. Heat is removed through natural convection, so the surrounding area must permit adequate airflow around the housing. This passive cooling method eliminates the need for an external fan or liquid-cooling circuit. The motor is supplied with no blocking brake, so an external mechanical lock or drive-generated torque must hold the load when the axis is stationary. Velocity information is provided through tacho feedback, which sends an analog speed signal to the connected controller for closed-loop regulation.

The unit is designed as a motor for analog drives and is compatible with transconductance amplifiers that regulate current in proportion to analog command signals. This control arrangement supports established motion systems that use proportional voltage commands and analog velocity feedback rather than a digital communication interface. The motor can operate in packaging equipment that requires rapid indexing, small machining centers that use controlled feed axes, and material-handling stations that depend on consistent acceleration and deceleration. Its electrical response supports accurate speed regulation, while the compact housing permits installation near the driven mechanism and reduces the length of the mechanical connection between the motor and load.
