What Is a 10 Inch Wheel Hub Motor?
A hub motor is a type of E-bike drive system that is built into the wheel hub. They are generally controlled by a motion sensor that detects pedalling and triggers the motor to provide assistance.
They omit a large number of transmission components and simplify the vehicle structure. However, they significantly increase the under spring mass and wheel hub inertia and have an impact on handling performance.
Omits a Large Number of Transmission Components
In-wheel motors, also called hub motors, are attracting attention as next-generation electric drive systems because they can 10 inch wheel hub motor make vehicles much lighter and more compact. They can reduce the weight of the vehicle, control the drive force to each wheel independently for torque vectoring, and expand cabin space. In addition, they can improve environmental performance, safety, and comfort. However, there is a bottleneck that needs to be overcome in order to commercialize the technology.
Traditionally, the size of in-wheel motors has limited their application. Achieving the large drive torque required for acceleration and hill climbing, while maintaining a sufficient maximum speed, has been difficult, especially with a motor that can fit inside a 16-inch wheel. NSK has developed a new motor-equipped wheel hub motor that achieves both high driving performance and compactness by using two motors and a special transmission. The motor uses two planetary gears to achieve both the driving torque and maximum speed, and it has the additional feature of smooth gear shifting even during acceleration by controlling the rotational speeds and torque of the two motors.
NSK has successfully demonstrated the world’s first transmission-equipped wheel hub motor in a breakthrough development intended to improve the environmental performance, safety, and comfort of automobiles. Based on this experience, NSK plans to further develop specific components such as the hub unit bearing with an integrated speed reducer and a one-way clutch unit, as well as the motor’s miniature cage and roller bearings and anti-corrosion bearing. This will enable the company to commercialize the new motor as soon as possible.
Simpler Vehicle Structure
Hub motors have a simpler vehicle structure than traditional electric vehicles that use a clutch, transmission and drive shaft. This is mainly because they do not have gears and differentials that increase the overall weight of the vehicle and require regular maintenance. They also have lower power-to-weight ratios than conventional motors.
Hub-motor-driven vehicles can also use differential steering, which is achieved by separating the rotational speed of the front and rear wheels. This can significantly reduce the vehicle turning radius and improve driving performance under certain circumstances. This technology is especially useful for special vehicles.
The basic principle of a hub motor is that it has a circular assembly inside its can (or casing) which holds windings made of turns of magnet wire around its projections or teeth (the rotor). This assembly is driven by the spinning of the axle, and the electric power produced is converted to torque to help you ride uphill.
The hub motor is controlled by a motion sensor that is usually built into the pedal crank – so you must be pedalling for it to work. At the lowest level of assistance you must still work quite hard to ride uphill – but at higher settings you can get near-zero effort climbing. However, there are some disadvantages to the system – it increases the unsprung mass of your vehicle and you may feel a slight difference in the way your bike rides.
Easy to Adopt a Variety of New Energy Vehicle Technology
The hub motor is a common choice for E-bikes because it’s made in mass quantities and relatively affordable. You can find it on cargo E-bikes, 3-wheeled E-bikes and even pedicab E-bikes. It’s a small electric motor that’s built up into the wheel hub either in the front or rear. It’s triggered by motion sensors on the pedal crank and when you are pedalling it will switch on and provide assistance. Once you stop pedalling it will switch off.
You can find both geared and brushless 10 inch wheel hub motors that are ideal for use 12 inch hub motor wheel in an E-bike. It is important to check the wattage of the motor to ensure that it can cope with the amount of power that you will be using. You should also look at the number of gears and the maximum torque of the motor.
The main advantage of a hub motor is that it can be integrated into a wheel and will work with almost any type of bicycle. It’s less expensive than a central motor system and can be used with most existing bikes. It can be mounted in the front or rear of the bike and can be designed to allow for regenerative braking. It’s also lighter than a direct drive system, making it easier to transport and install on the bike.
Easy to Operate
Unlike mid drive motors that integrate into the e-bike’s cranks, hub drive motors transfer power to the bicycle using their own axle. This makes them a more affordable option for many riders who want to upgrade an existing non-electric bike into an electric one. While the popularity of these motors is on the decline, they can still be found on a number of popular e-bike models from manufacturers like Bafang and Eunorau.
There are two main types of hub motors: geared and direct drive. Geared hub motors use a system of internal gears to turn the shell of the motor, whereas direct drive motors are completely gearless and operate on magnets. Both types can be used for either front or rear wheel drive, and both can offer a different experience depending on where the motor is located.
The newest front hub motor from Bafang, for example, boasts a rated power of 500 watts but, when paired with the appropriate controller, can actually deliver up to 864 watts. This system is also extremely quiet and can be easily adjusted to the level of pedal assistance you want through the Pedal Assist Sensor that comes with it.
Another manufacturer that produces front and rear hub systems is MXUS. They have a number of options in both geared and direct drive models, with a range of power outputs up to a whopping 4000 watts.
