MAC090A-0-RD-4-C/110-A-0/WI520LX

The MAC090A-0-RD-4-C/110-A-0/WI520LX from Bosch Rexroth Indramat in the MAC AC Servo Motors series offers a robust design with a continuous torque at standstill of 3.5 Nm and a torque constant at 20 °C of 0.34 Nm/A. With a peak pulse current of 76 A and a windings resistance of 0.56 Ohm, this low-inertia motor achieves rapid dynamic response while maintaining precise current-to-torque conversion. Its natural convection cooling type, combined with a rated ambient temperature range of 0 °C to 45 °C, ensures reliable operation without auxiliary fans. A convenient Side A power connection simplifies cable routing and reduces installation time.

The motor’s compact footprint is highlighted by its Motor Size 90 and Motor Length A configuration, delivering a weight of just 12.5 kg and a very low rotor moment of inertia of 20 x 10^-4 kg·m2. A long thermal time constant of 45 minutes provides stable thermal behavior under cyclic loading, while the absence of a blocking brake reduces mechanical complexity. The AC Servo Motor designation (MAC) reflects its permanent magnet excitation and compatibility with standard servo drive interfaces. Constructed to fit a B05 mounting pattern, this servo motor integrates seamlessly into existing automation layouts.

Engineered for precise positioning in robotics, CNC machining, and material handling, the MAC090A-0-RD-4-C/110-A-0/WI520LX excels where fast acceleration and deceleration are critical. Its balanced mass and low inertia deliver minimal overshoot and exceptional settling times. Fully rated for heavy-duty industrial environments, this AC servo motor is an ideal choice for demanding motion control applications.
