TECO Medium-Voltage Totally Enclosed Fan-Cooled Motor (IEC Standard)

As a core product in TECO’s medium-voltage motor series, the totally enclosed fan-cooled (TEFC) motor is fully designed and manufactured in compliance with IEC standards, delivering reliable, efficient, and stable performance for high-demand industrial applications. Adhering to IEC 60034 specifications, this motor excels in harsh working environments, making it a preferred choice for enterprises pursuing operational safety and energy efficiency.

The motor features a totally enclosed structure that effectively prevents dust, moisture, and corrosive substances from entering the internal components, paired with an external fan cooling system (IC411 cooling method) for rapid heat dissipation. Its housing is crafted from high-strength cast iron, ensuring excellent structural rigidity and thermal conductivity to maintain stable operation even under continuous medium-voltage loads. The low-vibration design meets IEC 60034-14 standards, with vibration levels above Class N, and the precision-machined components reduce operational noise to below 75 dB, creating a quieter working environment.

With a voltage range of 3kV-10kV and power coverage from 100kW to 1500kW, the motor adopts a three-phase asynchronous design with B-class temperature rise and a service factor of over 1.0. The F-class insulation system enhances durability, extending the service life to over 10,000 operating hours. It boasts strong overload capacity, capable of withstanding 150% rated load for 60 seconds, and offers stable speed regulation when paired with inverters, adapting to complex process requirements.

This versatile motor is widely applied in power generation, petrochemical, water treatment, and heavy machinery industries, such as driving pumps, fans, compressors, and conveyors. It supports modular installation and is compatible with international communication protocols for seamless integration into smart industrial systems. Backed by TECO’s strict quality control and global after-sales service, this IEC-compliant motor provides a cost-effective solution for industrial upgrading, ensuring long-term, low-maintenance operation.
