Press release from Höganäs AB of Sweden:
http://www.hoganas.com/en/News-Cent...rchive/Hoganas-launches-unique-bicycle-motor/
In connection with the inauguration of the Swedish pavilion at the World Expo in Shanghai this week, Höganäs AB launches a new motor for electric bicycles, particularly aimed for China and other Asian markets. The motor is made of metal powder, which enables a unique combination of low cost, low weight and high performance.
“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 75 kilometres, thanks to high efficiencyâ€Â, Höganäs Group CEO Alrik Danielson comments.
Höganäs AB is the leading manufacturer of metal powder. The company is continuously driving market development by extending the use of metal powder technology to new applications. The technology offers entirely new possibilities to create more efficient and lighter products with reduced environmental impact.
“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 generatorsâ€Â, Alrik Danielson continues.
The motor has been developed to minimise the environmental impact. The stator is based on metal powder manufactured from metal scrap, and the motor design allows a very efficient recycling. Furthermore, it uses less rare earth magnets and copper-wire than comparable conventional electric motors.
During the autumn Höganäs will market this unique motor concept towards end users in various suitable application segments starting with the bicycle industry. Höganäs intends to license and subcontract the production of the motors.
“With this bike motor, we want to show that we have the technology to support innovative electric motor applications development, By introducing it at the World Expo Höganäs wishes to contribute to the image of Swedish industry as entrepreneurial and innovative.†says Alrik Danielson.

ABSTRACT
Soft Magnetic Composite (SMC) challenges traditional material such as soft magnetic ferrites and electrical steels in applications with alternating magnetic fields. As the market potential is large this is an interesting area for the P/M industry. By utilising the features offered by the material itself as well as the
P/M forming technique new competitive electromagnetic designs can be realised. This paper will describe main features and benefits offered by the technology with focus on electrical motors. Finally, the latest and future materials will be presented.
INTRODUCTION
SMC-materials (Soft magnetic composites) are basically iron powder particles separated with an electrically insulated layer as shown schematically in Figure 1. The powder metallurgy (P/M) process has for long time been used to manufacture SMC components for high frequency inductor applications. These traditional SMC materials consist generally of iron particles distributed in matrix of organic materials. Due to the distributed air gap and good high frequency behaviour cores made of iron based SMC materials is the most cost efficient solution for inductive components in various filter and power conversion applications.
Recently the group of SMC´s has been expanded by the introduction of new materials. These materials do not contain any organic matrix that set limitations on the processing conditions. This makes it possible to manufacture components with significantly higher saturation induction, permeability as well as lower
hysteresis losses. As a result SMC´s are now also an alterative to electrical steels in applications in the low to medium frequency range such as rotating machines, sensors and fast switching solenoids. As the technology still is rather young applications, material, process and application development is ongoing at a high speed.
Basically there are three main features offered by the technology.
1. Unique combination of magnetic saturation and low eddy current losses. Figure 2 shows the position of SMC compared to traditional materials.
2. 3D-flux carrying capability.
3. Cost efficient production of 3D-net shaped component by the P/M process.
