Product Description:

The MAC041A-0-IS-2-E/050-B-0 is an AC servo motor in the MAC AC Servo Motors series developed by Bosch Rexroth Indramat. Designed as a drive element for position and velocity control on analog controller platforms, the motor delivers continuous shaft power to light-duty axes where compact dimensions and direct-coupled mounting are preferred. Its electromechanical design supports integration into machine tools, material-handling fixtures, and indexing mechanisms that require precise motion under closed-loop control. The brushless design also avoids the wear associated with mechanical commutation, making the motor suitable for repetitive operating cycles.

This model dissipates heat solely through natural convection, so an external fan is unnecessary as long as the applicable ambient limits are observed. Rotor position and speed are returned to the drive through integral tacho feedback, enabling proportional control without a separate resolver or encoder interface. Because the motor is supplied without a blocking brake, the axis must rely on drive torque or an external clamp to hold its position while power is off. Power conductors exit the rear housing through a connector oriented toward side B, simplifying cable routing when the motor is mounted against a gearbox or machine wall. This connector arrangement helps keep wiring clear of the output shaft and nearby mechanical components.

The motor has a frame size of 041 and a compact A length, which provide a small housing for installations with limited space. This combination lowers rotor inertia and supports rapid acceleration when the motor is connected to a light mechanical load. When paired with a compatible analog amplifier, the unit functions as a motor for analog drives, allowing established control racks to use brushless motor technology. The amplifier can process ±10 V command signals commonly used for speed or torque references in analog motion-control systems. Direct coupling can reduce the need for additional transmission components in indexing mechanisms, compact machine tools, and material-handling equipment. The integrated feedback signal also allows the velocity regulator to respond to changes in shaft speed during acceleration, steady operation, and deceleration.
