Product Description:

The MAC025C-0-QS-4-E/040-B-0/WI657LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It is intended for integration with analog drive amplifiers where accurate velocity and position control of rotary axes is required in industrial automation, such as material handling, packaging, and machine-tool feed modules. The motor operates as a synchronous unit energized by a three-phase supply, converting electrical power into controlled mechanical motion for these processes. Its construction follows the manufacturer’s modular stator and rotor design. This arrangement suits compact automation axes that need repeatable motion during frequent starts, stops, and direction changes.

In terms of mechanical construction, the motor is built to motor size 025, giving a compact frame diameter that pairs with planetary gearboxes and belt transmissions. The active magnetic stack follows motor length C, so continuous torque is tailored for light to medium duty axes. Thermal management relies on natural convection, meaning heat dissipates through the housing without external blowers or liquid circuits. The power leads exit through a connector on side B, simplifying cable routing in cabinets where the shaft faces the operator. For holding functions, the unit is supplied without a blocking brake, so external clamping or drive torque must secure vertical loads during power-off states.

Signal interfacing supports tacho feedback with an incremental or absolute encoder, allowing the control system to use either speed-proportional voltage or digital counts for closed-loop regulation. When operated with analog amplifiers, the motor functions as a motor for analog drives, and the drive card supplies current commands proportional to ±10 V. Standard mounting provisions accommodate an incremental encoder with standard mounting, providing 1 Vpp or TTL channels to the controller. These feedback and wiring features support older analog motion systems and keep signal routing straightforward in compact equipment.
