The e-bike motor developed in cooperation with partners was the result of a different, more innovative method of work, on that included several groups of associates.  The assembly is constructed of several complex parts and is highly sophisticated. Domel’s brushless motor installed in the e-bike drive is one of the best motors in terms of characteristics and efficiency. This provides the end application with lower consumption, good responsiveness in all conditions, and power that can be used by the end users.  

The electronics and software in the drive allow several customisations and adjustments that can be used in various types of battery-driven vehicles, such as: 

• cargo bikes,
• speed bikes,
• two- or three-wheelers,
• wheelchairs,
• cross motorcycles,
• small motorcycles,
• small boats,
• electric wheelchairs.

Turn your ideas into reality. 

Use 
The drive unit is currently adapted for demanding mountain bikers who like to climb forest paths as fast as they descend. It helps the rider with 750 W of power and up to 150 Nm of torque, which is as much torque as a small passenger car can achieve. 
The drive is versatile, perfect for experienced mountain bikers and those who want to travel a longer distance in a faster time. Thanks to the excellent Domel motor, the drive is energy efficient at the lowest level of assistance, and thus enables users to cycle long distances. 
Due to its high power, the drive is excellent for delivery or cargo bikes. 
Precise sensors and software enable optimisation that is suitable for lower speeds and higher starting torque. Due to the weight of the bike, the cyclist on a delivery or cargo bike starts to turn the pedals slowly, where even at a very low cadence the motor provides a great deal of assistance. The motor can then hold a nominal power of 450 W for a very long time, which is suitable for a powerful e-bike or delivery bike. Due to all these features, the drive is also suitable for tricycles or quadricycles. 
The drive is also installed on “speed” bikes, which are currently becoming more popular. With the same power, it helps the cyclist reach a speed of up to 45 km/h. 

Advantages: 

• Technological solutions have placed the new drive at the very top of performance in the global market. 
• It is classified in the highest quality class. 
• Domel’s drive has the highest torque on the e-bike market, and has the best weight / torque ratio in this respect. 
• The drive software can be customised. It is made in such a way that the buyer or distributor of an e-bike can optimise it on their own to meet their own needs or preferences with regard to the drive.  The speed is adjustable according to customer requirements. 
• This is the only product on the market where the motor helps at a very low cadence (and thus at low revs). 

The hub motor is a result of domestic know-how, designed with the most state-of-the-art approaches and simulation tools which allow us to use the materials efficiently. This reduces the environmental burden and complies with the required market guidelines, pursuing Domel’s development vision.

Domel’s direct drive motor for e-bike applications with the “pedelec” system does not use any pinions or gears. With its high efficiency, low weight and low noise, it is a very competitive product on the market with an excellent weight to torque ratio. Low energy consumption at a nominal power of 250 W and 25 km/h, and maximum power of 650 W allow a longer range on a single battery charge. The motor is designed in accordance with the 15194 standard for e-bikes. 

The hub motor has been developed and tested up to the sampling phase.

Technical data: 

The brushless 350 W DC motor powering the e-scooter is integrated in the front 10-inch wheel. The operation of the integrated motor ensures a comfortable and silent ride. Given its high power, the motor is very light due to the use of special technology. Its total weight including the hub is less than 2 kg.

The efficiency and power of the motor is ensured with a special technology that uses permanent magnets.

The whole scooter weighs 9 kg, making it among the lightest considering its power. Motor efficiency is between 85% and 90%. When descending a hill, the scooter will store energy for future rides by means of regenerative braking.

Applications of the electric motor:

• scooters,
• small bikes,
• folding bikes,
• trolleys,
• wheelchairs,
• mountain boards.
