Product Description:

The MAC090C-0-KD-4-C/110-B-0/WI522LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is supplied as a motor for analog drives and is intended for motion axes that require continuous torque production and closed-loop speed control. Within automated handling equipment or machine tools, the unit delivers rotational energy while providing real-time velocity feedback to its drive controller. That combination supports precise positioning during repetitive industrial tasks.

This model reaches a nominal speed of 1500 rpm, giving the controller a clear operating point for speed regulation. A centering diameter of 110 mm aligns the motor housing with the machine frame and minimizes radial runout at installation. Heat is removed by natural convection, so no external blower or liquid circuit is needed and mounting space stays compact. This cooling method reduces the need for auxiliary hardware around the motor. The electromagnetic design uses winding code KD, which indicates the stator wire gauge and impedance matched to the rated current of the companion analog drive. For velocity monitoring, the integrated tacho generator produces 3 V/1000 rpm, giving the controller a proportional voltage signal that scales linearly with rotor speed.

The power leads exit through a connector on side B, allowing cable routing away from moving machine members. Position data is generated by an incremental encoder with standard mounting, while additional speed feedback is available through the tachofeedback incremental or absolute encoder interface used with this motor. The motor has no blocking brake, so external clamping or drive torque must secure the load when power is removed. The tacho section is built to standard quality, supporting repeatable voltage output over the service life. This arrangement allows the drive to process motion feedback without requiring separate external sensing hardware.
