Product Description:

The MAC041A-0-FS-4-E/050-A-0/WI652LV is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. This rotor-stator assembly provides precise rotary motion for industrial automation equipment that relies on analog velocity and position loops. It is suited to positioning axes, feed systems, and other coordinated machine movements where smooth response is required. When connected to a compatible drive, the unit delivers controlled torque and speed so machine axes can follow programmed motion profiles with stable response during acceleration and deceleration.

Winding code FS indicates the electrical winding used in the motor and must be matched by the drive during current regulation. The motor has a frame size of 041, which keeps inertia low and suits compact axis layouts where quick speed changes are important. The housing uses natural convection for cooling, so ambient air removes heat without an external fan or liquid circuit. Electrical power enters through a connector on side A, allowing cable routing from the same end as the machine connection. The motor is supplied without a blocking brake, so load holding must be handled by the machine or by drive torque when power is applied.

The unit uses frame length A, which gives it the short housing length used for this motor size. It is built as a motor for analog drives, making it suitable for amplifiers that operate with voltage or current commands rather than fully digital control platforms. The motor family supports tachofeedback, incremental, or absolute encoder arrangements, depending on the feedback package installed. On this version, feedback is provided by an incremental encoder with standard mounting, which sends consistent signals to the drive during motion and at standstill. Stable feedback helps the amplifier maintain speed control during low-speed operation, reversals, and routine positioning moves.
