A new electric motor designed for use with electric bicycles, scooters and other lightweight vehicles has been launched by Swedish company, Höganäs. The motor takes advantage of "metal powder technology", resulting in high performance but with reduced size, with a range of up to 75km between charges. The motor has been shown during the World Expo in the heart in Shanghai, China, one of the world’s stronghold for electric bicycle manufacture and deployment due to its cost efficiency, flexible and environmentally-friendly means of transportation.
Metal powder technology involves reducing the metal to tiny, individual particles, heating and injection-molding them into the desired shape. The results can be stronger than other manufacturing methods.
“We chose the bicycle motor as a first application when introducing our new motor concept. The bicycle motor is very challenging, in terms of performance as well as cost, but we are confident that we have a unique product. It is lighter than other electric motors and in the e-bike it has a good range, up to 75km, thanks to high efficiency”, Höganäs Group CEO Alrik Danielson said. Höganäs says it is the leading manufacturer of metal powder, extending the technology to new applications.
“The e-bike motor is a good example of the Power of Powder. It is a highly efficient and very compact motor for direct drive applications. By combining high power per mass with a modular design, the motor is suitable for a wide range of applications in addition to electric bikes, such as scooters, other light electric vehicles, pumps, fans and generators”, said Danielson.
The stator is based on metal powder manufactured from metal scrap, and the motor design can be easily recycled, it also uses less rare earth magnets and copper-wire than comparable conventional electric motors according to Höganäs.
The new motors go on sale this fall, starting with models for the bicycle industry. “With this bike motor, we want to show that we have the technology to support innovative electric motor applications development,” said Danielson.
