When the power goes out, having a generator will come in handy. Since you rely on your household electrical system to run important devices, like the refrigerator or AC, waiting for the power to come back on isn’t always an option. To ensure you find the right generator for your needs, here are features to keep on your radar during the search. 

How Do Generators Work?

A generator is a machine that converts mechanical energy into electrical energy by rotating a wire coil within a magnetic field. The process is called induction. When the coil rotates, it creates an electrical current. The strength of this current depends on the number of turns in the coil and the strength of the magnetic field.

What Are the Key Components? 

1. Stator

This is the stationary part of a generator. It contains the wire coil that rotates within the magnetic field. The stator is typically made from cast iron, which has a high resistance to corrosion and wear. It's also insulated to protect against electrical shock. 

2. Rotor

This is the rotating part of a generator. It contains the magnets that create the magnetic field. It's made from a non-magnetic material, such as aluminum or brass. This prevents the magnets from interfering with the electrical current in the stator. 

3. Armature

This part contains the wire coil. It rotates within the magnetic field created by the rotor and stator. It carries alternating currents and is typically made from copper or aluminum, which has a high resistance to corrosion and wear. 

4. Commutator

This is a rotating switch that alternates the current flow through the armature coils. It's made from copper or brass, which has a high resistance to corrosion and wear. It's also insulated to protect against electrical shock. 

What Should You Consider When Choosing One?

The generator is connected to a circuit breaker panel to supply power to multiple devices on one circuit. To prevent an overload, consider what devices you'll still need to use until the power outage is resolved, including the refrigeration equipment. If you need to power multiple devices, pick a generator with a high running wattage rating. The equipment should also have a high surge wattage rating.
