Which motor is best for electric motorcycles?

When you think of electric motorcycles, what image comes to your mind? Most likely, it wasn’t someone running around on an electric two-wheeled machine. But that’s starting to change, and for the better. There are a wide variety of electric motorcycles on the market today, each with its strengths and weaknesses. This article will explore which motor is best for electric motorcycle use and why. We’ll also discuss some of the pros and cons of each engine so you can make an informed decision when choosing the engine that’s right for you.

What are the benefits of electric motorcycles?

Electric motorcycles are becoming more popular because they offer many advantages over traditional gasoline-powered motorcycles. These benefits include lower fuel costs, reduced emissions, and reduced noise.

One of the most important benefits is cost. Electric motorcycles generally use less fuel than gasoline-powered motorcycles, which can save you a lot of money in the long run. They also produce significantly fewer emissions, making them a greener choice for transportation. In addition, electric motorcycles are much quieter than gasoline-powered motorcycles, so they are ideal for urban environments where noise levels are important.

There are a few things to consider when choosing an electric motorcycle, including battery capacity and range. You must ensure your bike has enough battery capacity to reach your destination without a long charge. Additionally, the riding range of an electric motorcycle can be affected by factors such as rider weight and terrain. Therefore, it is important to test various models before purchasing.

different motor types

Many types of electric motors are available, each with advantages and disadvantages. Here, we look at the four most common motor types and discuss their suitability for electric motorcycles.

1) Permanent Magnet Motor (PMEM)

PMEM is the oldest type of electric motor and is often considered the best choice for electric motorcycles. They have a very high torque density (the ability to generate a lot of torque), making them ideal for high-torque applications like acceleration and hill climbing. Also, PMs do not generate much heat, so they are a good choice for high-power applications where heat is a concern.

One disadvantage of PMEMs is that they tend to be very expensive and produce a lot of noise. Additionally, they require a high-power power source to operate efficiently – which can significantly reduce the overall range of the battery pack. Finally, PMEMs are less suitable for low-speed applications because their torque drops rapidly as RPM increases.

2) Brushless DC Motor (BLDC)

BLDC motors are similar to PMEMs because they both have high torque and low-speed limits. However, BLDCs offer some advantages that make them ideal for electric motorcycles. On the one hand, BLDC motors are much quieter than PMEMs—even at high speeds. This makes them ideal for use in areas where noise is a concern, such as urban environments. Additionally, BLDCs are very efficient—they generate very little heat, making them ideal for applications where power is a concern.

One downside of BLDC motors is that they require a lot of power to operate efficiently – which can significantly reduce the overall range of the battery pack. Finally, BLDC motors don’t have the torque of a PMEM, so they are less suitable for high-power applications.

3) Torque Converter Motor (TCM)

TCM are a hybrid of PMEM and BLDC – they have the high torque of PMEM but the efficiency of a BLDC motor. This makes them ideal for applications requiring high torque and low-speed limitations. Additionally, TCEMs are significantly cheaper than PMEM or BLDC motors – making them ideal for applications where cost is a major factor.

One downside of TCEMs is that they are not as efficient as PMEM or BLDC motors, which generate more heat than either option. This can lead to overheating and reliability issues. Additionally, TCEMs do not have the low-speed limitations of PMEMs, so they are less suitable for applications where low-speed operation is a priority.

4) Stator Field Motor (SFEM)

SFEM is a new type of electric motor currently only available in prototype form. They are designed to be very efficient – they generate very little heat, so they are a good choice for applications where limited power is a concern. Additionally, SFEMs have very high torque – they can produce over 1,000 ft-lbs of torque. This makes them ideal for applications such as acceleration and hill climbing.

One downside of SFEMs is that they require a lot of power to operate efficiently – which can significantly reduce the overall range of the battery pack. Also, SFEM is still in development, which means there may be some performance issues that need to be addressed.

Brushless DC Motor

There is no single answer to this question, as it depends on many factors, including specific applications and budget constraints. However, some of the most popular brushless DC motors for electric motorcycles include motors from brushless motor manufacturers such as Bosch, Yamaha, and KTM.

There are a few things to keep in mind when it comes to electric motorcycle motors. First, make sure the motor you choose has enough power (watts/rpm) to handle the weight and speed of the bike. Also, pay attention to the torque specs – the high torque motor will provide more power at low speeds and help reduce engine vibration. Finally, be sure to check the compatibility of the motor with the bike’s battery configuration. Some motors require a dedicated battery compartment, while others can shut down the main electrical system.

Permanent Magnet Synchronous Motor

A permanent magnet synchronous motor (PMSM) is popular because it provides good power and efficiency. It’s also relatively quiet compared to other motors, making it ideal for riders who want a smooth ride.

One downside of the PMSM is that it doesn’t have a lot of torque, so it might not be suitable for riders who want to go fast. Additionally, PMSM motors can be expensive to purchase and maintain

Parallel synchronous motors

When choosing an electric motorcycle engine, the first thing to consider is its power output. Electric motorcycles come in different power ratings, from 250W to 1000W or more. The higher the power rating, the faster the motorcycle; however, it requires a more expensive battery and a larger motor.

Parallel synchronous motors are a good compromise between power and cost. It produces about 350W of power, enough to get most electric motorcycles going fast without getting too expensive or difficult to maintain. In addition, parallel synchronous motors are very reliable and have a long service life – they can even be used in boats!

One disadvantage of parallel synchronous motors is that they are relatively slow compared to other motors – typically around 50 km/h. This means they are not suitable for very fast electric motorcycles. However, if you want a robust motor that requires little maintenance, a parallel synchronous motor may be the way to go!


Electric motorcycles have various motors, and deciding which is best for you can be difficult. I’ve put together this guide to help you find the right motor for your needs. This guide covers everything from how torque affects performance to the battery range you should expect. By following these tips, you’ll be able to find the perfect motor for your electric motorcycle and get plenty of power without sacrificing reliability or handling.
