Product Description:

The MAC025C-0-QS-3-E/040-B-1/S001 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for closed-loop axis control, the unit converts analog current commands from a drive amplifier into proportional shaft torque and controlled speed. This operation provides precise motion for packaging machinery, small transfer lines, measurement tables, and other automated equipment. Its compact housing supports direct integration into assemblies that require consistent synchronous rotation and quick acceleration during repetitive operating cycles.

Thermal management relies on natural convection, so no external fan or liquid-cooling circuit is required. The motor has a frame size of 025 and a frame length of C, providing a compact mechanical envelope for space-constrained installations. Power cables enter through a connector on side B, keeping the drive end clear for coupling components and simplifying cable routing inside the machine. This connector position also helps separate the power conductors from sensitive feedback wiring when the cables are routed correctly. For vertical axes or applications that require stationary load retention, the installed blocking brake holds the rotor when the brake is engaged. The brake reduces the risk of load movement when the drive can no longer provide holding torque.

Position and speed signals are generated through tacho feedback and a second shaft end. The tacho feedback supplies an analog velocity signal to the connected drive amplifier, while the additional shaft end provides a mechanical interface for compatible auxiliary equipment. As a motor for analog drives, the unit works with current-controlled amplifiers that close the velocity loop externally and regulate motion from analog command signals. The QS winding code identifies the electrical winding configuration used with this motor size and compatible drive equipment. A centering diameter of 040 mm locates the motor accurately against the mounting surface, helping maintain alignment between the shaft and the connected coupling. The housing arrangement supports installation with gearboxes, machine plates, or other components that accommodate the motor’s mounting dimensions.
