✅ Operating Boundary for Selection

1. モーター: 3-phase asynchronous motor 0.75kW; 380~480V 3-phase power supply
2. 負荷の種類: Light constant-torque load preferred; 180% short-time overload for max. 60s

4. インストール: IP20等級, must be installed inside control cabinet, cannot be exposed directly on site.

⚠️ Industry Status

This model has been discontinued by the manufacturer for many years. Units available on market are mostly surplus stock or used reclaimed drives. Not recommended for new projects; Lenze i500 series is preferred for replacement.

I can prepare a E82EV751K4C to i500 replacement selection & parameter migration comparison table if needed.

Method to Verify Suitability of Lenze E82EV751K4C for Your Application

Core premise: This obsolete 8200 Vector 0.75kW sensorless vector inverter is only suitable for spare part replacement on legacy machines; not recommended for new project procurement.

Verification covers four aspects: load power & トルク, process control requirements, 環境 & installation conditions, project type (new retrofit / maintenance spare).

1. 力 & ロードマッチング (Primary Check)

2. Short-time overload requirement: マックス. 180% overload for up to 60 秒. Suitable for applications with mild start-stop shock and short peak load.
3. Compatible load types:

✅ おすすめ: Light constant-torque loads (conveyor rollers, traction rollers, small mixers), variable torque loads (小型ファン, 小さなポンプ)

✅ Inertial loads: Paper rolls, コンベヤーベルト, fast stop with external brake resistor (onboard brake transistor)

❌ Not Suitable

モーター出力 >0.75kW; continuous heavy load, frequent heavy impact loads (破砕機, stamping mechanisms)
