The moment of inertia is 109 J (×10⁻⁴ kg·m²) — this is a high-inertia rotor relative to the output power, which means the load-to-rotor inertia ratio stays manageable even with a heavy payload coupled directly. Expect the velocity loop to need a lower proportional gain than a low-inertia servo of the same power class. ## Inertia and tuning — what the 109 J figure means for your axis A 109 J rotor inertia paired with a 5.0 kW output places this motor in the medium-to-high inertia range — the inertia ratio between the load and the rotor is the dominant factor in settling time. If your load inertia is below 200 J (×10⁻⁴ kg·m²), the auto-tuning in the MR-J4 drive series will converge without manual notch filters. Above that, expect to dial in a low-pass filter on the velocity loop to keep the resonance below 200 Hz. ## Active production — sourcing and lifecycle The estimated lead time from the factory is 1–10 working days, though actual lead time depends on order volume and regional stock levels.","metaTitle":"Mitsubishi HG-SR502B AC Servo Motor 5.0 kW, with Brake","metaDescription":"Mitsubishi Electric HG-SR502B AC servo motor, 5.0 kW output, 44 Nm brake torque.
