Jõumuundur

Jõumuundur is an Estonian term that translates to "power converter" or "torque converter" in English. It refers to a device that modifies the characteristics of power or torque from a source to meet the requirements of a load. The specific type of jõumuundur can vary greatly depending on the application.

In the context of mechanical engineering, a jõumuundur often refers to a hydraulic torque converter, commonly found in automatic transmissions of vehicles. This device uses hydraulic fluid to transfer rotational power from an engine to a transmission, allowing for a smooth start and variable torque multiplication. It essentially acts as a fluid coupling that can also increase torque when needed.

Beyond automotive applications, the concept of a jõumuundur can extend to electrical systems. Here, it might describe devices such as AC-DC converters, DC-DC converters, or DC-AC inverters, which all modify electrical power characteristics. The term's broadness suggests that its precise meaning is determined by the context in which it is used, be it mechanical or electrical power transmission.
