What the headline numbers buy you
The ECMA-E21320SS sits in Delta's 220 V AC servo motor line at 2 kW rated output, delivering 9.55 N-m of continuous torque at 2000 r/min and a 33.03 A rated current, with peak torque capability up to 28.65 N-m when the drive calls for it. That 2000 r/min base speed with a 3000 r/min ceiling gives the machine builder the constant-torque region most packaging and converting lines actually run in, with the upper band available for fast-index moves. The power-rating figure of 62.5 kW/s is the acceleration headroom — high enough that point-to-point moves on a 2 kW axis don't sit and cog while the rotor winds up. Mechanical time constant of 0.96 ms and electrical time constant of 15.86 ms are the loop-tuning numbers a controls integrator reads first when sizing the velocity-loop bandwidth against the load inertia.
Insulation resistance is rated above 100 MOhm at DC 500 V, which is the figure a site electrician looks at when a motor comes back from a wet environment or after long storage. It sets the floor for the megger test the maintenance crew runs before re-energising a damp cabinet.
Lifecycle status and quoting posture
Lifecycle stage is recorded as current, with a typical shipment window of 1-10 working days against an order.
Second-source question: drop-in for the RS variant?
The motor is also sold paired with the ASD--2023-B drive as a kit (ECMA-E21320SS mated with that 220 V three-phase ASDA- servo drive), which is the configuration most integrators buy when commissioning a fresh axis rather than retrofitting a single motor into an existing cabinet.
