FOUR key things in the past 20-30 years are causing the physical world to electrify:
1) magnets got way better, enabling high torque permanent magnet motors.
1) magnets got way better, enabling high torque permanent magnet motors.
2) power transistors (whatβs needed to power electric motors and convert DC <> AC power) got more power dense and more efficient. Silicon is being displaced by Silicon Carbide and Gallium Nitride.
3) batteries got both high energy density and cheap, thanks to Lithium-Ion and the scale from electric vehicles driving down battery cell costs.
4) scale from EVs and drones led to purpose-built single-chip solutions for battery management and motor control, driving lower costs, better overall integration, and letting new companies benefit from abstraction when using these technologies.
