Rotary power is often described in terms of Horsepower, while Electrical power is described in Kilowatts (kW) or Kilovolt-Amperes (KVA). The conversion of frequency (hertz – Hz), voltage, and/or phase (3 phase, 1 phase) are inherent in &lt;/ins&gt;this &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;process&lt;/ins&gt;.&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Another method is direct coupled converters that directly couple the motor shaft to the generator shaft using a mechanical coupling, and adjusting &lt;/ins&gt;the &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;speed of &lt;/ins&gt;the &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;drive motor to vary the rotational speed of the generator, thus varying the output frequency. An adjustable speed electronic drive  is used for this purpose, instead of a conventional motor starter.Finally, the most sophisticated and most costly method is to build the motor and generator onto a single common shaft, called common shaft frequency converters&lt;/ins&gt;. &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;In &lt;/ins&gt;this &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;case, the frequency change is made by winding &lt;/ins&gt;the &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;motor with a different number of electrical poles than the generator. &lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
