Electric trikes, or e-trikes, are becoming increasingly popular for their convenience, efficiency, and environmentally friendly nature. One of the standout features of e-trikes is their ability to accelerate quickly. This blog series will explore the factors behind their rapid acceleration, starting with a look at how electric motors work and the role of torque.
How Electric Motors Work
Electric motors are the heart of e-trikes, converting electrical energy into mechanical energy. Here’s a breakdown of how they function:
- Electromagnetic Induction: At the core of an electric motor is the principle of electromagnetic induction. When electric current passes through a coil of wire in the presence of a magnetic field, it generates a force that causes the coil to rotate. This rotational movement is what powers the e-trike’s wheels.
- Components: The main components of an electric motor include the stator (the stationary part that generates the magnetic field), the rotor (the rotating part that turns the wheels), and the commutator (which ensures the current flows in the right direction).
- Type of Motor: Kwolity E-trikes use hub motors that are integrated into the wheels, providing direct drive without the need for chains or gears.
The Role of Torque in Acceleration
Torque plays a crucial role in how quickly an e-trike accelerates. Here’s why:
Definition of Torque: Torque is a measure of the rotational force applied to an object. In the context of e-trikes, it’s the force that the motor generates to turn the wheels. The higher the torque, the faster the wheels can spin from a standstill. Imagine you are opening a jar of jam. The force you apply to the lid to twist it open is torque. When you twist the lid, you’re using torque to turn it and open the jar.
Similarly, for an e-trike, torque is the force that helps the wheels start turning and get the trike moving quickly.
- Instant Torque: One of the biggest advantages of electric motors is their ability to deliver maximum torque instantly. Unlike internal combustion engines that need to rev up to generate power, electric motors provide full torque as soon as you as you turn the motor on. This means e-trikes can accelerate rapidly, providing a smooth and powerful start.
- Comparison with Internal Combustion Engines: Internal combustion engines rely on fuel combustion, which take time to build up power. Electric motors, on the other hand, have fewer moving parts and can generate torque immediately, resulting in quicker acceleration and a more responsive ride.
Mitigating Acceleration in Kwolity E-Trikes
- Throttle Control:
- Gradual Throttle Application: Riders are encouraged to apply the thumb throttle gradually rather than all at once. This helps to prevent sudden jerks and provides a smoother acceleration. The thumb throttle is a great way to get the trike rolling, especially at the lights or crossings, or up an incline.
- Electronic Speed Limiter:
- Pre-set Speed Limits: Kwolity E trikes have electronic and sprocket ratios that cap the maximum speed the e-trike can reach. This ensures that acceleration is kept within safe limits.
- Customisable Speed Limits: The electronics on a Kwolity E Trike have pre-set speed limits, which can be particularly useful for beginners or those who prefer a more controlled ride. This is done through the central console and is preset when delivered to the customer. You can see how this is done if you go to YouTube and type in “how does the SW900 console work”.
- Power Mode Settings:
- Multiple Power Modes: Kwolity E-trikes come with 5 different power modes, such as eco, normal, and full power. By choosing a lower power mode, riders can reduce the acceleration rate and enjoy a more leisurely ride. Its roughly starts with 20% power then works its way up to the 5th power mode which is full power or 100%. If the rider wants to fully exercise without power at all, the central console allows the rider to go down to a zero-power setting.
- Weight Distribution:
- Balanced Design: Kwolity E-trikes are designed with balanced weight distribution parameters that help maintain stability during acceleration. This includes the placement of the battery, motor, 20-inch wheels, and the rider.
- Adjustable Seats and Cargo: Riders can adjust the seat and handlebar to help achieve better weight distribution and reduce the impact of sudden acceleration. The cargo baskets at the rear also assist in stabilising the trike, whether it is the tilting model or the rigid Rail Trail.
By building these measures into the product, Kwolity E-trikes offer a safer and more enjoyable riding experience, especially for seniors and those new to electric E trikes.
