Product Description:

The MAC025B-0-ZS-4-E/040-B-0/WI656LV/S001 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is an AC servo motor intended for closed-loop motion axes that rely on external speed and torque control. Within automated machinery, this motor converts electrical commands from the drive into precise mechanical rotation, enabling positioning or velocity control on packaging lines, material-handling gantries, pick-and-place stations, and similar equipment. In closed-loop service, the connected amplifier uses the feedback signals to correct speed deviations as load conditions change during operation.

Cooling is handled by natural convection, so cabinet airflow must remove radiant heat without an auxiliary fan. Because no separate fan is used, heat leaves the housing through its surface and the surrounding air. Shaft position is monitored by an incremental encoder with standard mounting; the square-wave channels generated by this sensor allow the drive to derive velocity while a zero index supports homing routines. Power and protective earth conductors exit through a connector on side B, which can simplify cable routing when that side faces the supply trunk. The frame uses the B size code, which corresponds to the flange dimensions and rotor diameter used for this motor.

The stack length is coded as 025, indicating a short magnetic core that helps reduce inertia for responsive acceleration on light-load axes. Classified as a motor for analog drives, it works with legacy controller families without requiring digital communication. The motor is supplied without a blocking brake, so mechanical holding during power-off conditions must be provided externally. This approach keeps the rotor assembly lighter and suits applications where the load is counterbalanced or otherwise secured at standstill. For systems that need speed correlation to an external reference, the platform also supports tacho feedback, incremental encoder, or absolute encoder variants while keeping the same general mounting interface.
