Product Description:

The MAC025B-0-ZS-4-E/040-B-0/WI671LV/S001 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is an AC servo motor intended for use with analog drive amplifiers where precise, closed-loop axis control is required on printing lines, packaging equipment, and general automation cells. In that role, the motor converts electrical commands into proportional torque and speed so machine axes can follow process setpoints with repeatable accuracy. Because it is used in closed-loop service, the paired amplifier can correct for normal load changes during operation.

The motor has no blocking brake, so any load-holding function must be provided by external mechanics or by the drive itself. Heat is removed solely by natural convection, eliminating the need for forced-air or liquid cooling hardware and simplifying cabinet layouts. The cooling method leaves the housing free of auxiliary fan components, which is useful where surrounding space is limited. The rotor and stator stack follow length code 025, and the housing frame is size B; together, these physical codes indicate the continuous torque range and mounting dimensions used within the MAC family. Power conductors enter through a connector on side B, an orientation that helps cable routing when the motor flange is fixed against a machine back plate.

The unit is classified as a motor for analog drives, meaning its winding and feedback selections align with amplifiers that process ±10 V velocity or torque references. For velocity sensing, it carries a composite feedback package described as tacho feedback with an incremental or absolute encoder; this arrangement supplies real-time speed information together with a high-resolution position signal to the drive. The primary position device is an incremental encoder with standard mounting, which produces phase-shifted pulse trains that the controller counts for displacement tracking. These feedback channels are wired through shielded low-voltage lines and share the multi-pin circular connector, which helps maintain EMC compliance without extra glands. This arrangement supports both velocity regulation and position tracking through the same motor interface.
