Product Description:

The MAC025B-0-ZS-4-E/040-B-1/WI668LV is a servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. This model is intended for integration with analog servo amplifiers, where it transforms drive current commands into precise rotary motion for light-duty automation axes, pick-and-place heads, and gantry stages. By delivering controlled torque and speed, it supports repeatable positioning tasks in industrial machinery. This type of motor is well suited to short indexing moves and steady low-speed operation in compact handling equipment.

Heat produced during operation is dissipated through natural convection, so the housing cools without fans or forced airflow. The internal rotor stack corresponds to motor length 025, which gives the motor a short axial profile for shallow machine layouts. Electrical power reaches the windings through a connector on side B, helping route cables alongside adjacent components and away from the mounting face. A standard blocking brake is included to hold the shaft when drive current is removed, which helps prevent unintended load movement during stops or power loss.

Rotor position is resolved by an incremental encoder with standard mounting, providing line-driver signals for speed and position processing by the connected controller. The motor also supports tacho feedback and incremental or absolute encoder options, which broadens compatibility with both legacy control racks and newer motion systems. Its electromagnetic core uses motor size B, giving it a mechanical envelope consistent with other units in the same frame group. The unit is configured as a motor for analog drives, so it fits applications built around earlier analog motion platforms while still providing closed-loop feedback for controlled operation. That flexibility helps the motor fit control layouts that use different feedback methods without changing the basic mechanical package.
