Let’s Brief You on Recent Developments for Electrostatic Motors

Summary
Ryan Inis’s YouTube video explores how electrostatic motors are challenging the dominance of electromagnetic motors due to the scarcity of certain materials used in electromagnetic motors, such as rare-earth magnets and copper.
Electromagnetic motors function by passing a current through copper windings to create magnetic fields that turn a rotor, whereas electrostatic motors date back to the 1740s and work through the attraction and repulsion of high voltage electric charges, requiring less electrical current.
While the high voltage needed for electrostatic motors presents practical challenges, such motors offer higher torque with less friction and heat, making them suitable for low-speed, high-torque industrial applications.
Furthermore, they consume 90% less copper compared to electromagnetic motors, and no electrical steel or permanent magnets.
The electrostatic motor is making a comeback, with increasing interest due to its potential to deliver highly efficient, economical motors.
