Product Description:
The MAC025B-0-ZS-4-E/040-B-1/WI670LV belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is an AC servo unit intended for axis control on analog drive modules, where commanded current is converted into precise rotary motion for positioning, speed regulation, or tensioning tasks inside automated machinery. In operation, the motor responds to changing drive commands and helps maintain stable motion during repeated starts, stops, and speed changes. Its compact construction, combined with closed-loop feedback capability, allows installation in space-constrained equipment while still providing the accuracy needed for repetitive industrial cycles.
The motor uses the 025 length code and a Size B frame, giving it a short stack that reduces mass while preserving enough magnetic surface for moderate torque output. A standard blocking brake is integrated to clamp the shaft whenever the drive is disabled, which helps prevent drift on vertical or torsion-loaded axes. Thermal dissipation relies on natural convection, so no external fan or liquid circuit is required, although surrounding air must be able to move freely around the housing. Power reaches the stator windings through a compact connector on side B, which helps keep cables clear of moving machine parts and supports neat routing in tight cabinets.
Feedback integration uses tacho feedback with an incremental or absolute encoder, giving the control system a choice between speed-related tacho signals and multi-turn position data. The base configuration includes an incremental encoder with standard mounting that emits phase-shifted signals compatible with analog servo amplifiers, allowing the drive to track rotor movement during normal operation. Because the unit is a motor for analog drives, its electrical feedback arrangement matches legacy MAC control platforms that process current and speed commands with analog circuitry. The brake and feedback package supports repeatable stop-and-start motion on compact axes without auxiliary cooling hardware.
