Product Description:

The MAC041B-0-BS-4-E/050-B-0/WI652LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as an electromechanical actuator for position-controlled and speed-controlled machinery, converting electrical command currents into precise rotary motion. A permanent-magnet rotor interacts with the stator windings to generate torque with low rotor inertia and responsive acceleration. The motor can operate pick-and-place heads, small conveyors, packaging spindles, and other compact automation axes that require repeatable movement. Closed-loop operation allows the connected drive amplifier to correct changes in speed or position caused by varying loads.

The motor is supplied without a holding brake, so an external mechanism or drive-applied torque must secure the load when the axis is stationary. Heat is dissipated through natural convection, eliminating the need for an auxiliary fan when the motor is installed with sufficient airflow around its housing. Rotor velocity is monitored through tacho feedback, which sends an analog speed signal to the connected drive amplifier for closed-loop regulation. The motor size is 041, providing a compact housing suitable for machinery with limited installation space. Power conductors terminate at a connector on side B, allowing cables to be routed away from nearby moving components. The short housing and low rotating mass help the motor respond quickly during repetitive starts, stops, and direction changes.

The motor has a frame length of B, which provides the active stator length required for its torque range while retaining a compact axial profile. Its winding is designed for analog drive systems, including compatible VT-MAC or KDS controllers that regulate motor current according to incoming command signals. Fine position measurement is provided by an incremental encoder mounted at the standard feedback location. The encoder produces square-wave output channels that external control electronics can count and interpolate for accurate position tracking. The combined encoder and velocity feedback paths support precise movement during indexing, conveying, and spindle operations. The mounting arrangement allows the motor to connect to suitable gearheads, couplings, or machine assemblies used on light-duty automation axes.
