Everything You Need to Know About Electric Starters

Kickstarting engines was the norm, even when it seemed physically demanding for everyone. Some may have complained, but that won’t start engines, would it? So, when an easier alternative came into the picture, what do you think it had? Clue: it’s something electric.

What are Electric Starters?

An electric starter is a device that starts an engine or motor using electricity instead of the usual manual labor. It’s usually powered by a battery and designed to crank engines instantly. Think of it like switching your lights on, but instead of a light, you’re turning on an engine.
Some come pre-installed in some devices and machines for convenience, while some are upgrades and installed manually.

What are They Used For?

Obviously, electric starters are primarily used for starting engines, but do they have any other uses? Apart from starters, they can also accelerate, reverse, or stop the engines. But it all comes down to two important functions:
1. Start and Stop: They are used to initiate and terminate the operation of electrical motors. It does so by safely connecting and disconnecting a device’s electrical power supply.
2. Overload Protection: Electric starters monitor the current being drawn into a motor. It also disconnects the power supply if the current exceeds a safe limit. This function protects the motor from overheating or potential damage.
In essence, we can boil it down to the safety and protection of electric motors. They control the flow of electricity to the motor, and from there, they prevent surges that may lead to overloads.

The Different Types of Electric Starters

Now, these electric starters may be simple in function, but they come in many types. The good news is, we can break them down into just a handful of types. In fact, it boils down to just five:

Direct-On-Line (DOL)

This is the most basic type of electric starter out there, which also makes it the most widely used. It connects the motor directly to the power supply and allows the motor to start at full voltage. It’s cheap and easy to use, making it the top choice for everyday tools and appliances.

Star-Delta

In comparison to DOL, this type of electric starter is mainly used for bigger motors that need a gentler start. It got the name Star-Delta because it reduces the initial voltage by starting in a “star” configuration. After that, it switches to a “delta” setup for normal operation. Star-Delta starters are often used in industrial applications but can also be found in common power tools.

Soft Starters

If you find Star-Delta a soft starter, it’s understandable, but they’re actually different. They both aim to reduce the starting current, but they do it differently. Soft starters gradually increase the voltage to the motor over time, while Star-Delta switches between low voltage and high voltage.
They’re found in systems that require smoother startup and shutdown, like HVAC systems and conveyor belts.

Autotransformer Starters

Another name implying electric starter that uses a transformer to reduce voltage at startup. An autotransformer starter allows for a controlled and smoother start, especially in large motors. Think industrial machinery and autotransformer starters are used there.

Variable Frequency Drives (VFDs)

These are, by far, the most advanced and most flexible option among electric starters. A Variable Frequency Drive can start a motor and control its speed and torque. The key to its function is control, which is why it’s frequently used to control fans, pumps, and compressors.

Where Can We Find Them?

We touched on a few applications where the different types of electric starters can be found. But unsurprisingly, they can be found in almost every appliance and tool we use every day. Here are a few of them:

● Everyday Power Tools: Electric start lawn mowers and basic pressure washers are some of the most common.
● Home Backup Solutions: An electric start generator is the most common. When a storm hits or if you’re in an RV living situation, this becomes a staple.
● Engine Upgrade Kits: If you’re into niche engine upgrades, an electric motor starter is always included on your list.
● Outdoor Cooking: If you’re into camping trips or backyard grill sessions, an electric charcoal starter is your friend.

Are They Essential Even in 2025?

The short answer is absolutely yes.
It’s safe to say that most of us don’t want to go back to doing everything manually. We’re moving to the age where almost everything we use has something electronic about it. Engines and motors are not an exception. They’re slowly becoming integrated with electronics, and anything manual is taken away.
We want our lives to be easier, and if electric starters are essential for that goal, then they’ll be everywhere. It will become a norm and not an exception, so for 2025 and beyond, yes they are essential.

Closing Words

Electric starters have been around for longer than we realize, and advances for them have been made. The good thing is that we don’t need to know every minute detail about it. Far more people are working on it and all we need to do is to use them properly.

Frequently Asked Questions (FAQs)

How does an electric starter work?
It uses electricity from a battery to crank an engine instead of manual labor.

What is the benefit of an electric starter?
It provides ease of operation, significant safety, and convenience for almost everyone.

Do we always need an electric starter?
No, it’s not always necessary. However, electric motor starters are often essential for safety reasons.
