Product Description:

The MAC025B-0-ZS-4-E/040-B-0/WI652LV is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. The unit is intended for integration with analog drive amplifiers, where it delivers commanded torque and speed for precise axis motion in automated assembly, printing, or packaging lines. Its electromechanical construction allows continuous closed-loop control, supporting tight process repeatability in multi-axis industrial machinery. In this role, the motor converts electrical input into controlled rotary motion while the connected amplifier manages the commanded operating response.

Heat generated during operation is removed by natural convection, eliminating the need for forced-air accessories and simplifying cabinet design. The frame is categorized as frame size B, giving a compact cross-section that matches small-to-medium mechanical assemblies, and the magnetic stack depth uses the 025 length code to balance inertia with continuous torque. Power conductors enter through a connector on side B, keeping the opposite face clear for mounting to gearboxes or machine plates. As a motor for analog drives, it accepts ±10 V speed or torque references that are common in legacy Rexroth controllers. This arrangement supports straightforward cable routing in compact machine layouts.

The design omits a mechanical holding device, and the shaft is supplied with no blocking brake, so external clamping or drive torque must secure vertical loads when power is removed. For velocity-matching applications, the motor can be equipped with tacho feedback, an incremental encoder, or an absolute encoder. This unit carries an incremental encoder with standard mounting that delivers pulse trains to the controller for high-resolution speed loops. The feedback signal supports accurate speed regulation and stable response as operating conditions change.
