Product Description:

The MAC041A-0-FS-3-E is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drives, it delivers controlled rotary motion in compact positioning axes that require high operating speeds. The size 041 frame with length code A allows the motor to fit into narrow machines without adapter plates. Its compact housing makes it suitable for small indexing tables, automated handling equipment, and other applications where installation space is limited.

Thermal management relies on natural convection, so no external blower or liquid cooling circuit is required, and the housing releases heat directly into the ambient air. Under nominal excitation, the rotor reaches a rated speed of 6000 rpm, which affects the commutation frequency required from the amplifier and the mechanical throughput of coupled loads. Torque rises linearly with phase current according to a constant of 0.330 Nm/A, allowing force output to be calculated during acceleration. Dynamic feedback is generated by an internal tachogenerator that produces 0.75 V/1000 rpm, giving the drive a proportional velocity signal for closed-loop control. The low rotor inertia of 0.70 × 10⁻⁴ kg·m² supports rapid directional changes with reduced overshoot, which can shorten motion cycles in small indexing systems.

Mechanical integration follows the B05 flange mounting style, so the pilot diameter and bolt circle comply with IEC dimensions for installation in compatible brackets. Power is delivered through a connector located on side B, keeping the cable route clear of the driven shaft. The feedback package includes tachometer feedback and a second shaft end, allowing the additional shaft end to accommodate an external encoder or another compatible mechanical attachment. The stator uses winding code FS, which indicates the resistance and inductance values associated with compatible analog MAC drives. The frame size and length combination provide the compact proportions required for installation while supporting the motor’s applicable thermal and continuous-torque characteristics.
