Product Description:

The MAC025B-0-ZS-4-E/040-B-0/WI670LV/S006 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. In industrial automation, this motor couples with matching analog drives to position machine axes precisely. The frame size and internal electromagnetic design are intended to support low inertia, so small process deviations can be corrected rapidly. Installed in conveyors, pick-and-place heads, or indexing tables, it provides the rotational energy that the controller modulates in real time through current commands.

Heat is removed solely by natural convection, so sufficient airflow around the housing must be maintained. Because the shaft is supplied without a blocking brake, the machine must rely on external brakes or motor holding torque to secure vertical loads when power is off. Its mechanical outline corresponds to Motor Size 025, giving a flange diameter suited to this size class. The active magnetic stack is identified as Motor Length B, which indicates the axial dimension and continuous torque capability within the size class. Power is routed through a connector mounted on side B, simplifying cable runs when the motor is oriented in line with gearboxes or carriages.

Position feedback is handled by tachofeedback with an incremental or absolute encoder, allowing either speed-based or true position-based control loops. The default sensor shipped with this code is an incremental encoder with standard mounting, so the drive receives uniform quadrature signals for commutation and motion profile generation. The unit is classified as a motor for analog drives, meaning command and feedback lines operate through voltage and current levels rather than digital fieldbus packets. This makes the motor suitable for axes that use conventional analog servo amplifiers in packaging or transfer equipment.
