Product Description:

The MAC041A-0-FS-3-E/050-B-0 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is an AC servo motor intended for closed-loop positioning tasks in automated machinery, where rotational accuracy and repeatability are required for analog drive controllers. By converting electrical command signals into controlled shaft torque and speed, the motor serves as a compact actuator for packaging stations, light pick-and-place axes, and inspection equipment. Its compact format also suits smaller machine sections where installation space is limited but stable servo response is still necessary.

Within the type code, the winding designation FS indicates the copper fill and impedance used with common analog amplifiers. The motor length index 041 identifies the active stack height, which supports moderate continuous torque while keeping overall mass low for quick acceleration. Heat is removed through natural convection, so the unit should be mounted where ambient air can circulate freely, and no fan or liquid loop is required. Power conductors are routed through a molded connector on side B, which allows the cable to exit opposite the instrumentation side and simplifies wiring. This arrangement also helps keep the connection path clear in narrow machine layouts.

For velocity monitoring, the second shaft end carries a permanent-magnet tachogenerator, and the feedback bundle delivers tacho feedback to analog regulators for proportional speed control. The frame code A places the motor in the smallest housing of the series, permitting installation on compact linear stages without exceeding a 40 mm center height. Because the motor has no blocking brake, vertical axes must rely on electrical holding torque or an external mechanical lock when the load must remain fixed at standstill. The unit is engineered for analog drives, so its voltage constant and tacho signal bandwidth match classic current-controlled servo amplifiers. Consistent factory tolerances keep the mechanical interface and feedback phasing aligned across units, which helps maintain predictable motion response during operation.
