Rotary Converters

Single phase 240V or 415V to three phase 240V or 415V:
The rotary phase converter will artificially generate the third leg of a three phase system from the two lines of a single phase system. The generated three phase supply depends to the level of available single phase. For example if the supply is 240V, it generates three phase close to 240V, if it is 415V it generates three phase close to 415V. Rotary Phase Converters are one of the oldest and economical option to run a three phase system. However thee power quality is often compromised with poor voltage balancing and for most equipment loads, an over sized converter must be specified to enable motor start-up. In other words, this type of converter is the cheapest solution but with least efficiency. These inefficiencies lead to increased energy consumption and eventually may cause damage to the three phase equipment, especially digital or electronic machinery. We should also remember that this type of converter has problem of unbalanced three phase output. Balance of the three phase generated output, is very much load dependent. It is extremely difficult to tune a static phase converter for wide range of possible applications. |
Depending on the unit rating and specifications, it may vary in size and shape.

The rotary converter with an idler motor acts as a three phase wave generator. The idler motor is under no physical load, but it cleans up the generated signal.
This product provides more power to the tool motor, and also brings it up to speed faster. The rotary converter is best served when you have a motor which requires frequent Start/Stop, and you need the full power of the motor. Furthermore, a single rotary converter can drive several different 3-phase motors which are much smaller than the idler motor. This means, a decision has to be made with the required power which commands the size of the idler motor.
Important points to note:
The run capacitor of a converter has a fixed value, and as a result the power quality is very much load dependent and only acceptable at one specific load condition. And in any other load conditions, the output symmetry of the three phases will become less perfect. Manufacturers usually compensate for this mismatch by using a larger frame size in a rotary converter. For example, if the internal motor used is 10 -20 times bigger than the largest external motor, the output symmetry would not be affected much whether a load is connected or not, but this will cost a compromise on other disadvantages such as the larger size, the higher weight, less efficiency, higher starting currents and higher overall running cost.
We provide custom designed Rotary Converters for wide range of three phase application and ratings.
Simply plug and run your three phase (415V) system using 240V power using our Rotary Converter.
240V single phase input to three phase 240V output is also available.
Package includes:
- Rotary Controller
- Idler Motor
- Two Plugs (One for the Idler Motor and One for the Output Load)
The following items are in the range of our general production. We will be glad to customize and design systems suitable for your application.
