Product Description:

The MAC090B-0JD-4C/110-A-1/WI524LV is a three-phase AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it supplies controlled rotary motion to machine axes, packaging stations, and pick-and-place heads that rely on tight velocity and torque regulation. It is also suitable for retrofit installations that keep the existing mechanical assembly while updating the motor.

At standstill, the electromagnetic system can generate 6.7 Nm of continuous torque while drawing 18.2 A of phase current. Heat is removed by natural convection, so the housing must remain in unobstructed airflow without forced fans. Integrated position feedback comes from an incremental encoder that delivers 625 lines per revolution and operates from a 5 V logic rail. The rotor reaches a nominal speed of 3000 rpm, which supports high throughput while maintaining stable operation.

For short bursts, the stator can deliver 137 A of pulse current, enabling rapid acceleration despite a rotor moment of 36 × 10⁻⁴ kg·m². Torque rises in direct proportion to current at 0.41 Nm/A, which helps keep amplifier response predictable. A holding brake rated at 6.5 Nm engages from a 24 VDC supply to secure loads when power is removed. Installation is centered by a 110 mm pilot diameter, and the 60-minute thermal time constant suits duty cycles with extended dwell periods. Electrical response is also influenced by 2.0 mH of winding inductance and 0.38 Ω of resistance, which affect current behavior during dynamic operation.
