On the maximum power transfer theorem within electromechanical systems
On the maximum power transfer theorem within electromechanical systems
Conditions for maximum power transfer are considered within electrical, mechanical and electromechanical systems. The familiar concept of resistance load matching within an electrical system is extended to a mechanical system, and is 50% efficient. For electromechanical systems, the transfer of maximum power from one domain (say, the electrical) to the other (say, mechanical) is also 50% efficient. However, when losses occur in both the electrical and mechanical domains, the concept of load matching must be applied within the domain to which power is being delivered; efficiency is now less than 50%, which is most easily seen from the source domain.

Abstract
Conditions for maximum power transfer are considered within electrical, mechanical and electromechanical systems. The familiar concept of resistance load matching within an electrical system is extended to a mechanical system, and is 50% efficient. For electromechanical systems, the transfer of maximum power from one domain (say, the electrical) to the other (say, mechanical) is also 50% efficient. However, when losses occur in both the electrical and mechanical domains, the concept of load matching must be applied within the domain to which power is being delivered; efficiency is now less than 50%, which is most easily seen from the source domain.
