Electric motors and drives and Transformers and power electronics

Energy flows from transformers and power electronics to electric motors and drives; their prices have moved together.

Electric motors and drives (energy) and Transformers and power electronics (energy): 2 relationships.

How they are linked

1. Energy flow

Physical flow · 9% of flow · Transformers and power electronics → Electric motors and drives

Variable-speed drives control motor speed.

• 9% of Transformers and power electronics's energy goes this way

2. Price link: drives

Cost and price · Strong · Both ways

Variable-speed drives and inverters control most modern motors, so the two are often sold together. Monthly moves correlate at 0.26 and yearly at 0.77, a common driver from electrical equipment costs and industrial investment.

• 0.26 monthly change correlation
• 0.77 12-month change correlation
• 0.67 fitted elasticity
