Product Description:

The MAC041B-0-QS-2-E/050-B-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is designed for closed-loop motion systems that use analog velocity or torque commands. The motor converts current from a compatible drive amplifier into controlled rotary motion for actuators, feed rollers, and small transfer axes. Its compact housing is suitable for automated machinery where installation space is limited and accurate speed regulation is required.

The motor is supplied without a blocking brake, so stationary loads must be held by drive-generated torque or an external clamping device. Heat is dissipated through natural convection, with the housing transferring internally generated heat to the surrounding air without a fan or liquid-cooling circuit. Rotor speed is monitored through integrated tachometer feedback, which supplies the analog controller with a continuous voltage proportional to rotational speed. The motor has a size 041 frame, providing a compact flange and centering arrangement for compatible gearheads or machine plates. Its motor length B balances the active electromagnetic stack, torque capacity, and rotor inertia for responsive motion on smaller machine axes.

The three-phase power leads exit through a connector on side B, allowing the power cable to be routed away from adjacent equipment and moving components. Classified as a motor for analog drives, the unit operates with compatible MAC amplifiers that regulate motor current in response to external reference voltages. This control arrangement supports stable speed and torque loops without requiring a digital fieldbus connection at the motor. The compact format allows the motor to be installed on feed mechanisms, indexing assemblies, and other low-inertia axes that require repeatable rotary movement. Its integrated feedback channel helps the connected amplifier correct speed deviations caused by changing mechanical loads during operation.
