Product Description:

The MAC041A-0-FS-2-E is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive controllers, it converts commanded current into precise shaft motion for small material-handling axes, auxiliary packaging stations, and other compact automation tasks that require accurate speed and position response. A permanent-magnet rotor provides the excitation field, while electronic commutation sequences the stator currents for controlled rotation. Integrated thermo switches monitor winding temperature so the motor can be installed in any mounting orientation without requiring separate external temperature sensors.

This model delivers a continuous torque of 0.64 Nm at a continuous current draw of 2.00 A, giving the drive amplifier a clear relationship between current demand and available load capacity. Under rated conditions, the shaft reaches 6000 rpm, which suits high-cycle positioning and moderate-power spindle duties where quick indexing is needed. The housing carries an ingress rating of IP65, helping protect the internal windings, magnets, and feedback components from dust and low-pressure water exposure during normal operation. This combination of torque, current, speed, and sealing makes the motor suitable for compact machinery that must maintain repeatable motion in enclosed industrial equipment.

Thermal energy leaves the stator through natural convection, which eliminates the need for a separate fan and keeps the motor layout simple. A rotor inertia of 0.70×10^-4 kgm² supports rapid acceleration and deceleration, which is useful on axes that change speed frequently. Velocity feedback is supplied by an internal tacho generator with a constant of 0.75 V/1000 rpm, allowing an analog drive to monitor speed directly at the motor. The electromagnetic design produces a torque constant of 0.330 Nm/A, so current response remains predictable across the normal operating range. The mechanical interface follows the IM B5 flange pattern from IEC 60034, allowing direct attachment to compatible machine brackets or gearheads without custom adapter plates.
