TMEIC

What TMEIC does

TMEIC Corporation (株式会社TMEIC) is a privately held industrial systems joint venture, established in 2003 and equally owned by Toshiba and Mitsubishi Electric. The company designs, manufactures, and services power electronics (variable frequency drives), rotating machinery (industrial motors and generators), and automation/control systems for energy-intensive industrial customers. Its product portfolio spans the TMdrive family of medium- and low-voltage AC and DC drives (with flagship offerings TMdrive-70 and TMdrive-XL85), the 21-H and 21-G motor series with capacities up to 23,000 kW, PV inverters (creator of the world's first 1000 kW PV inverter), and specialized port automation products (Maxspeed crane controls, MaxShorePower, Hybrid-Power Guardian, E-Tanker, Operations Viewer, Fleet Management System).

Core technology is grounded in proprietary power semiconductor switching (IEGT), inverter architecture (3-level NPS for 99% peak conversion efficiency), MPPT algorithms (99.9% dynamic MPPT efficiency, Fraunhofer-verified), and water-cooled drive designs achieving 20+ year MTBF. TMEIC operates eight manufacturing facilities across Japan, India, USA, and China, and sells through direct enterprise field sales channels with regional HQs in Tokyo, Houston, Beijing, Bengaluru, Singapore, and Uxbridge. The customer base spans metals, ports and terminals, renewable energy, mining, oil and gas, cement, paper, rubber and plastics, water/wastewater, utility plants, and substation solutions, with named accounts including Steel Dynamics and DP World Vancouver.

The business model is project-based and quote-driven, with multi-year contracts and lifecycle service revenue (commissioning, renewal parts, field service, 24/7 emergency support, training). Revenue streams are predominantly hardware sales (drives, motors, inverters, crane systems) complemented by professional services and custom-engineered solutions. In FY2024, the company reached record revenue and profit globally with orders exceeding ¥400 billion for the first time.
