Product Description:

The MAC041A-0-IS-2-E/050-B-0/S001 is a compact AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts electrical input into controlled torque for automated tooling, conveyor indexing, and light assembly actuators. The motor serves as the prime mover for positioning axes that require controlled acceleration, deceleration, and speed. Its rotor and stator arrangement supports smooth velocity regulation across the low-to-medium power range commonly used in factory machinery.

Heat generated during operation is removed through natural convection, eliminating the need for an auxiliary fan or a liquid-cooling circuit. This passive approach reduces the number of moving components and allows the housing surface to transfer heat directly to the surrounding air. Motion feedback is provided through integrated tachofeedback, which produces a voltage proportional to shaft speed for closed-loop regulation by the connected drive. A motor size of 041 provides a compact mechanical envelope, while the A length keeps rotor inertia low for rapid start-and-stop cycles. This combination supports responsive motion in pick-and-place stations and other equipment where the axis changes speed frequently. Power conductors exit through a connector on side B, allowing the cable path to remain toward the rear of the machine and away from wiring on the opposite side.

The motor is supplied with no blocking brake, so an external mechanism or drive-produced torque must hold the shaft when the axis is stopped. Vertical or gravity-loaded applications may therefore require gearing, a mechanical lock, or another holding device to prevent movement after motor power is removed. The proportional feedback signal is compatible with control systems that regulate speed by comparing measured shaft velocity with the commanded value. Its current-controlled operation also suits established transconductance amplifiers used in mature production equipment, while the compact housing supports installation where available machine space is limited.
