TMEIC Delivers Next-Gen Self-Starting Motors with Ultra-Low Starting Current for Superior Efficiency
TMEIC Corporation (President & CEO: Akira Kawaguchi; hereinafter, “TMEIC” or “the Company”) has introduced a self-starting 4-pole synchronous motor with minimized starting current*¹ to ensure successful startup and operation where power and water are limited. By July 2024, TMEIC has shipped 20 units in capacities of 10MW, 14MW and 16MW.
The self-starting, low-current synchronous motor primarily serves the oil and industrial gas industries. It is compact and not heavier than traditional frames but possesses a robust structure that ensures integrity, facilitates handling, uses less space and lowers installation costs.
Key Benefits
1.Enhanced plant stability with digitized excitation control and ultra-low starting current
By digitizing excitation*² control and optimizing the timing for the motor to reach full operating speed, TMEIC’s advanced design minimizes starting current, voltage drops and vibrations. Developed using high-precision analysis and cutting-edge 3D modeling technology, this ensures smoother startups, reduced system strain and superior stability for continuous plant operations.
2. Improve space utilization and reduce costs
The compact design that is 15% smaller and 9% lighter than traditional models optimizes space usage and cuts installation and maintenance costs. A smaller footprint than conventional frames allows for more flexible plant layouts and lower operational expenses.
3. Versatile cooling solutions for any environment
In addition to its air-water-cooled models, TMEIC is now introducing the IC616 air-air-cooled design, eliminating the need for cooling water, which makes it ideal for dry or remote locations such as oil & gas facilities. The air-air cooling system enhances flexibility, simplifies maintenance and reduces the need for utility resources, thereby offering efficient, low-maintenance operation across diverse installation scenarios.
[Product range]
- Totally enclosed air-air cooled (IC616): Up to 22.35 MW
- Totally enclosed air-water (IC81W): Up to 27.5 MW
This versatile motor range delivers high performance and reliability, setting new standards in efficiency and adaptability in oil and industrial gas production.
