Electric motors and drives: Relationships

Every element and industry that Electric motors and drives is linked to, and how. Each pair has its own card explaining the relationships between the two.

  • Steel: Every electric motor's magnetic core is a stack of thin non-oriented electrical steel, and the quality of that steel sets a large part of the motor's energy losses. It is a specialised grade made by few mills, so its supply and price follow their own cycle rather than the general steel market. (researched)
  • Vehicles, ships, rail, aircraft: Electric vehicles move on traction motors, and most of those motors use rare-earth permanent magnets made almost entirely in China, so the motor is where the vehicle industry's exposure to magnet supply sits, as 2025's export curbs showed. (researched)
  • Water and sanitation: Water and sewage services are mostly a matter of moving water uphill and through pipes, so motor-driven pumps and blowers use most of a utility's electricity, and efficient motors and drives are the main lever on its energy bill. (researched)
  • Copper: Motors are one of copper's biggest uses, because their stator windings, and in some designs the rotor, are copper; tighter efficiency classes such as IE3 cut resistive losses largely by adding active material, so efficiency rules raise copper use per motor. (researched)
