Product Description:

Bosch Rexroth Indramat manufactures the MAC090B-0-PD-4-C/110-B-0/WI524LX/S001 as part of the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts command voltages into controlled torque for positioning, conveying, and general axis duties within industrial automation cells. Its integrated feedback and mechanical format allow it to pair with compatible Indramat analog servo amplifiers for stable motion during continuous operation. This arrangement supports applications that need repeatable speed control and accurate axis response without a separate motor-mounted cooling assembly.

The motor has a centering diameter of 110 mm, which helps align the flange with a gearbox or machine frame and reduce mounting runout. Cooling is handled by natural convection, so heat leaves through the housing surface without a built-in fan. The stator uses the PD winding code, which indicates the electrical values used with compatible analog drive amplifiers in this frame size. Under rated excitation, the shaft reaches a nominal speed of 1500 rpm, so the drive can regulate velocity around a fixed operating point. A built-in tacho generator outputs 3 V/1000 rpm, allowing the controller to monitor actual speed as an analog voltage proportional to shaft rotation.

The unit is supplied without a blocking brake, so load holding must be provided by external hardware or continuous drive torque when the axis is stopped. Power conductors terminate through a connector on side B, which helps route cables away from the output shaft area and nearby machine components. For position feedback, the motor uses an incremental encoder as the primary feedback device, while the tacho supplies speed data for the analog control loop. Speed feedback follows a standard tacho quality classification, which provides baseline linearity suitable for general analog velocity control.
