Innomotics 1LE0 Series of Low Voltage 3-Phase Asynchronous Motors (IE3)

The Innomotics 1LE0 Series of low-voltage, 3-phase asynchronous motors are designed for general-purpose use. They feature a Totally Enclosed Fan Cooled (TEFC) housing with IP55 environmental protection, making them suitable for a wide variety of applications. These motors comply with international standards such as ISO, IEC, and GB.

The 1LE0 Series motors are engineered for constant or adjustable speed with continuous duty operation (S1), covering a broad speed range and providing reliability and efficiency in industrial settings.

Features of Innomotics 1LE0 Series (Low Voltage, IE3)
