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.","metaTitle":"Delta ECMA-E21320SS Servo Motor, 2 kW, 9.55 N-m","metaDescription":"Delta ECMA-E21320SS AC servo motor, 220 V series, 2 kW, 9.55 N-m rated torque at 2000 r/min, available to order against the BOM.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"ECMA-E21320SS","Weight":"9.2 Kg","Product No.":"ECMA-E21320SS","description":"Ac Servo Motors","Product Type":"AC Servo Motor Drive 220V Series","Shipping Weight":"11.5 Kg","lifecycle_stage":"current","Rated current (A)":"33.03","Rated torque (N-m)":"9.55","Estimated Lead Time":"Usually ships in 1-10 working days.","Power rating (kW/s)":"62.5","Rated speed (r/min)":"2000","Maximum torque (N-m)":"28.65","Insulation resistance":"100M? , DC 500V above","Maximum speed (r/min)":"3000","Rated output power (kW)":"2.0","Electrical time constant (ms)":"15.86","Mechanical time constant (ms)":"0.96"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$957.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/88b29396e0ea7f946b1c4dc682217678.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/delta/ECMA-E21320SS","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/delta/ECMA-E21320SS when reusing this data.
