Product Description:

The MAC90C-0-GD-4-C/110-A-1/WI520LX/S001 is an AC servo motor produced by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. Classified as a motor for analog drives, it is intended for position and speed control tasks in industrial automation equipment such as packaging lines and transfer stations. The unit integrates an incremental encoder in the standard mount position for basic feedback. It also ships with factory-wired power, signal, and brake leads for connection to matching Indramat drives, which helps keep external wiring direct and organized at the machine interface.

Its rated operating point is a nominal speed of 3000 rpm, where the motor can deliver a continuous stall torque of 9.6 Nm while drawing a continuous stall current of 24.8 A. During normal duty, the phase conductors carry 20.2 A, and the recommended cable cross-section is 2.5 mm² for that load. Acceleration reserves are available through a peak pulse current capability of 196 A, and the electromagnetic design converts current to torque with a constant of 0.43 Nm/A. The stator windings have an inductance of 1.5 mH and a resistance of 0.24 Ω, which influence current rise and heat generation. Heat produced under these conditions is dissipated by natural convection, so no forced airflow is required.

A holding brake rated at 6.5 Nm is included to secure vertical or load-holding axes when power is removed, and it operates from a DC 24 V coil. The housing has an IP65 rating, which helps keep dust and water jets away from internal components during normal industrial use. A thermal time constant of 60 min indicates that the motor can absorb heat for a meaningful period before internal temperature rises fully stabilize. The 110 mm centering diameter supports accurate flange seating, and the incremental encoder continues to provide position feedback for controlled stopping and drive regulation during operation.
