Product Details

Engine description

This high and low voltage three-phase asynchronous motor series is a new generation product based on the long-term design and manufacturing experience of the company's stable high voltage three-phase asynchronous motor, combined with the latest international standards.

This series of high- and low-voltage three-phase asynchronous motors meets the IEC standard, which is suitable for motors with a power range of 0.12 kW to 1000 kW and a voltage of 50 V to 1 kV. Under this standard, motors are capable of continuous operation at their rated power with a temperature rise within the specified insulation temperature class. The majority of motors covered by this standard are classified for service type S1 (continuous service). However, some motors that are rated for other duty cycles are still capable of continuous operation at their rated power and these motors are also covered.

In addition, this series of motors is marked with any ambient temperature within the range of -20 °C to + 60 °C. The nominal efficiency and efficiency classes are based on the ambient temperature of 25 °C in accordance with IEC 60034-2-1. Motors rated for temperatures outside the range of - 20 °C and + 60 °C are considered to be of special construction and are consequently excluded from this standard. Smoke extraction motors with a temperature class up to and including 400 °C are covered by this standard.
