Rotor inertia is 54.95 × 10⁻⁴ kg·m², which puts this build in the medium-to-high inertia band — the matched drive has to be sized for the acceleration current this inertia draws at the target cycle time, not just the steady-state 3.0 kW. Regenerative energy handling matters on this frame: capacitance absorbs 42.43 J per regen event with another 67.93 J from empty-load deceleration at 3000 r/min to stop — exceeding that on a vertical-axis emergency stop will fault the drive unless an external regen resistor is fitted.","metaTitle":"Delta ECMA-L11830SS Servo Motor with Brake, 3.0 kW, 400 V","metaDescription":"Delta ECMA-L11830SS ECMA-series AC servo with brake, 3.0 kW at 400 V / 1500 r/min, 20-bit encoder, 180 mm frame.
