Product Description:

The MAC090A-0-RD-4-C/110-A-0/WI520LV/S001 servo motor is produced by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It delivers closed-loop rotary motion for automated machinery that relies on analog velocity or torque commands, converting those signals into precise shaft movement for positioning, indexing, and speed regulation in packaging, printing, and material-handling stations. As a motor for analog drives, it is optimized for ±10 V command interfaces rather than digital fieldbus control. This arrangement lets the paired amplifier respond predictably to command changes during acceleration, deceleration, and steady-state speed control.

Mechanical alignment is assisted by its centering diameter of 110 mm, which helps seat the motor face accurately in the mating flange. Heat generated in the stator is removed through natural convection, so no external blower or liquid loop is required and airflow around the housing should remain unobstructed. The power leads exit through a connector on side A, which can simplify cable routing when the motor is mounted with the shaft facing forward. Position information is returned by an incremental encoder with standard mounting, allowing the associated drive to regulate speed and torque with consistent feedback resolution. Because the cooling method is passive, the motor can be installed without extra fan hardware, provided surrounding space is kept clear for heat dissipation.

The motor is supplied without a blocking brake, so vertical or load-holding axes need an external locking method when power is removed. At standstill, the shaft is retained only by magnetic detent effects, so any axis that must remain fixed under load needs separate holding hardware. For diagnostic flexibility, tacho feedback for incremental or absolute encoders can be selected, allowing the controller to use either coarse velocity data or higher-resolution position information as needed by the application. It also comes with standard tacho quality, which supports general-purpose operation where a higher-precision feedback option is not required.
