A rotary 3 phase converter operates by using a rotary device called an idler generator to convert single-phase power into three-phase power. The idler generator consists of a motor with a special design, capable of generating the missing two phases required for three-phase power. Here’s how it works: When the converter is initially turned on, the idler generator motor spins up to full speed. This motor is connected to a single-phase power source, which provides power to the first phase of the idler generator. As the motor rotates, it generates a magnetic field that induces a voltage in the second and third phases. This voltage is then tapped and combined with the original single-phase power to form three-phase power. The converter’s output is connected to the load, allowing it to receive the desired three-phase power supply. This process enables the use of three-phase equipment or machinery in situations where only single-phase power is available.
