Quick Summary

A dynamotor is a device that combines an electric motor and an electric generator into a single unit. It is used to convert electrical power from one form to another. For instance, a dynamotor can transform alternating current (AC) into direct current (DC), which is useful in applications like welding. It can also generate high-frequency AC power for purposes such as induction heating. The term "dynamotor" is a blend of "dynamo" (an older term for generator) and "motor".12
