Buying Guide: Electric Motor for Go-kart

After looking at the variety above, you may have already interpreted that there is an extensive range of electric motors available on the market. To make sure you do not end up with the wrong product, we have compiled a comprehensive buying guide to help you choose the right one. 

Factors to Consider When Purchasing an Electric Motor for Go-Kart

When it comes to purchasing a good electric motor for your go-kart, there are a few parameters that you should weigh different models against. Doing so will help you identify the right motor for your needs. We have listed some of these aspects below:

Power 

The first and foremost thing that you should consider in any potential model is its performance. You should evaluate its ability to power your go-kart by checking the various values like torque and speed. In fact, simple multiplication of torque and speed values will give you the exact power the motor can output. 

A motor with higher power output will propel your go-kart faster. Power rating between 2,000 and 3,000 watts is highly desirable for adult go-kart motors. Since they are heavier and have to pull more weight hence higher power. If you are building an electric go-kart for juniors, a motor with 1,000 watts or above is perfect. 

Voltage

The voltage of an electric motor signifies its electrical pressure. It is important because other aspects of electrical operation like current and speed depend on it. Most electric motors for go-karts operate between 24 to 72 volts of rated voltage. The word rated implies the motor can operate reliably at this range. 

It is also important to match the voltage of your motor with the voltage of your battery. Using a high voltage motor with low voltage batteries will lower its performance. And a battery with a higher voltage than the motor will reduce its lifespan causing it to eventually fail. 

Current 

Current denotes the flow of electrons in a circuit. It is measured in Ampere or amps. The higher the rated current of a motor, the more electricity it will draw, meaning a more powerful battery will be required. 

For example, a battery with a 100 Ah rating can power a 20-ampere battery for 5 hours. So you should carefully check the rated current of an electric motor to pair it with a compatible battery. 

Components

As you may have already noticed, some of the models on our list are standalone motors, while others come with a few accessories, Iike hardware, tools, and speed controller. If you choose to purchase a complete kit, you won’t have to bother with separately purchasing the compatible parts with the motor. But if you like choosing parts yourself, a stand-alone electric motor would be a better choice. 

Electric Motors vs Internal Combustion Engines 

The biggest choice any DIY go-kart builder has to make is choosing between an electric motor and a gas-powered engine. In this section, we will tell you why the former is a better choice for your go-kart. Take a look!

They Are Clean for the Atmosphere

The biggest benefit of electrical engines is that they don’t release any unpleasant fumes, odors, small toxic particles, or harmful gases into the atmosphere. Plus, they do not consume huge amounts of oil like internal combustion engines, which helps preserve resources. Plus, it saves you from the pollution that happens because of oil disposal. 

They Generate Low Noise and Vibration

This is the exact reason why Tesla became a favorite amongst car buyers. Electric motors generate significantly lower noise and vibration than internal combustion engines. They operate by creating a magnetic field that allows smooth and frictionless rotation of their components, emitting little to no vibration in the process.

They Generate More Motion Than Heat

As their name suggests, internal combustion engines use heat to generate motion. The entire process involves pressurized fuel, micro-explosion, and friction between different components. However, despite the complex process, these engines only manage to partially convert energy into motion. 

Electric motors, on the other hand, generate very little heat during their operation. Plus, they efficiently convert almost all the electrical energy into motion. 

Their Maximum Torque Is Constant

Torque is the rotational force of an engine. Where combustion engines see a steady increase in torque as the RPM increases, electric motors boast maximum torque even at minimal RPM. Thus electric go-karts not only have the highest traction at the start but also deliver higher acceleration. 

Tips for Maintaining an Electric Motor for Go-Kart

The motor is the fundamental component of any electric go-kart. Unlike their initial bulky and energy-consuming versions, the electric motors manufactured these days are extremely compact and energy-efficient. However, that does not mean that they don’t require any maintenance. Here are some tips to help you maintain your go-kart motor in its optimum condition:

Practice a General Cleaning Routine

You should develop a regular cleaning routine for your go-kart motor. You’ll be surprised at how something as simple as cleaning impacts the performance and lifespan of your electric motor. Removing dust, excessive grease, and other debris improves airflow to the motor, which helps keep it cool. 

Plus, it also presents you with an opportunity to inspect the other parts of the motor, like couplings and belts, if they are working fine. 

Check the Lubrication

Keeping your electric motor well-lubricated is a good practice. However, if you end up overlubricating the motor, it will cause internal problems. Each electric motor requires different amounts of lubricant. You should carefully check the instruction manual to learn about its requirements, as premature and late lubrication can both lead to excessive wear and tear. 

Inspect the Bearings

A motor’s bearings are subjected to the most wear and tear. Hence you should check them regularly. Worn-out bearings can quickly dampen your go-kart’s performance. Regular cleaning and maintenance, proper lubrication, and correct alignment can help keep your bearings in good condition. 

FAQs: Electric Motor for Go-kart

Although we have explained everything about go-kart motors in great detail if you still have any concerns, here are some FAQs to answer your queries:

Will a starter motor work for my electric go-kart?

Yes, you can use a starter motor for your go-kart, but there are some limitations to its usage. For example, assuming you’ll use a starter solenoid to run that starter motor, it won’t give you much speed control. You’ll just be able to turn it on and off. 

Can I use an AC motor for my DIY go-kart? 

Yes, you can use an AC motor for your DIY go-kart, but it is not a good idea because you’ll need a compatible inverter for it. Go-karts need lots of power to start under load. So even if your kart needs about 1,000 watts when it is running, it’ll need about 5,000 watts of power to start under load and, a 5,000-watt inverter is an expensive piece of equipment. 

Can a starter motor run continuously for long? 

No, a starter motor cannot run continuously for long. They are designed to run continuously for up to 30 seconds requiring a 1 or 2-minute cool-down time between operation cycles. If you try to run one continuously under load, its rotor and stator windings will melt. 

What type of motors works with go-karts? 

Go-kart motors run on direct current (DC) that is supplied to them via rechargeable batteries. The best go-kart motors are specifically designed and shaped for recreational vehicles. Any motor that works with ATVs, scooters, and bicycles will also work with a go-kart. They feature a compact design and come with mounting brackets for easy installation. 

What’s better – a complete go-kart motor kit or just the motor alone? 

It really depends upon your personal preference. If you like to source compatible parts yourself, the motor alone is a better choice. It will give you the freedom to choose the components like battery and speed controller according to your requirement and personal preferences. 
But, if you don’t want to be bothered with the hassle of buying parts separately, a complete motor kit will be a more suitable choice. 

Conclusion

Go-karts that operate on electric motors are both more convenient and eco-friendly than their gas-powered counterparts. Whether you are building a go-kart yourself or are looking to replace the old one on your go-kart with a more powerful option, we have listed the 12 best electric motors for go-karts that you can check out.
