Key Takeaways

- Single conductor motors and generators operate based on the principle of electromagnetic force.
- The speed and direction of a motor are influenced by the electromagnetic force and the opposing force.
- In a steady state speed, the current will be zero and no mechanical power output will be produced.
- A single conductor generator can be constructed by placing a conductor in a magnetic field and rotating it.
- In rotating machines, the interaction between the stator and rotor produces electromagnetic torque.
