Home > The Unique Yamaha Advantage
Yamaha Generators are designed to supply powerful electricity everywhere and anytime. |
For outdoor leisure The Yamaha Generator features a lightweight, compact body and portability. It is very convenient to put in your car and optimal for use in camping. |
For outdoor work The Yamaha Generator features ensure it is easy to operate and can be used outdoors. It can really show it’s worth and performance on construction sites and in remote areas. |
At construction sites Yamaha Generators have excellent durability and powerful generation ability. They also consume less fuel for an economic power supply. |
For photographers Yamaha Generators are useful when taking photographs and filming for a long period of time. It can, of course, supply extra electricity for lighting effects at night, too. |
For restaurants, shops & outdoor markets Yamaha Generators run very quietly and are perfect for use in stores and market stalls. You can illuminate the exterior and run the eftpos, making the appearance and convenience more attractive to the customers. |
For anything The inverter model is also available and designed to supply perfectly stable electricity, even better than a domestic power supply. It can be also used as a power supply for micro-computer assisted power tools. |

Damper Winding Adopted for Greatly Reduced Waveform Distortion Ratio Adding a damper winding (short-circuit ring) to the alternator’s rotor serves to correct the distortions in magnetic flux occurring during electricity generation and makes it possible to greatly reduce waveform distortion ratio by adding a skew to the alternator core. This greatly expands the range of electric appliances the generator can be used with to include those operating with microcomputer control, such as air-conditioners, computers and uninterruptible power supply (UPS) systems that require quality electricity. FW series generator is a wave distortion ratio of about 6.2% at a rated load connection.

Perfect power! “Sine wave” electricity for precision machinery The alternate current is generated by means of an inverter system. This inverter system employs Pulse Width Modulation (PWM) to output high-quality “sine wave” electricity. This means it can be used safely with precision equipment like a microwave oven, PCs and appliances with microcomputer functions.

![]() Waveform distortion of under 2.0% This generator can be used for appliances that require “sine wave” electricity, such as appliances with built-in microcomputer units or microcomputer control systems. Merit of multi-polar alternator
Adoption of an inverter system enables the alternator to generate highly efficient high-frequency 3-phase AC current. The alternator for inverter generators is a multi-polar type composed of two 18-pole stator coil(s) and a rotor with six permanent ferrite magnets. Adoption of this highly efficient alternator makes it possible to achieve a dramatically lighter and more compact unit compared to conventional alternators with bi-polar synchronous rotors. |
A wave distortion ratio of less than 2.0% is achieved. This model can be used with equipment that requires stable frequency and voltage (as defined by an ideal "sine wave" when graphed), like products with built-in computer functions and micro computer -controlled power tools or equipment like projectors.

POWER REQUIREMENTS Calculating your total power needs 1. Firstly, list the item you need to run that has the highest starting wattage. 2. Then take the running wattage of this item and add to it the running wattage of all the other items you need to power simultaneously. This is your total running (rated) wattage requirement. 3. Next, take the start up wattage of the same item and add to it the running wattage of all the other items you need to power simultaneously. This is your start up (maximum) wattage requirement. You should try to pick a generator with the power outputs that are greater than the totals you calculated above. |

This chart lists average power requirements. Your particular tool or appliance may require more or less than the listed wattage. * Where START wattage is the same as RUN wattage, this signifies no additional power is required for starting. |
