Australian research team develops a new high-speed electric motor that can reduce costs and increase the battery life of electric vehicles

CTOnews.com, September 15, with the continuous development of the electric vehicle industry, electric motors and other related technologies used in electric vehicles are also making continuous progress. Due to the shortage of raw materials in the market, many manufacturers begin to develop faster electric vehicle drive motors, mainly because the faster the speed of the drive motor, the smaller the motor volume, which helps to reduce the consumption of raw materials.

A research team at the University of New South Wales (UNSW) in Australia has developed a new high-speed electric motor that can reach a speed of 100000 revolutions per minute, newsroom reported. The researchers say the new electric motor achieves a maximum power and speed that exceeds the existing laminated permanent magnet synchronous motor (Interior Permanent Magnet Synchronous Motor), making it the fastest laminated permanent magnet synchronous motor built with commercial laminated materials in the world.

The trend for electric vehicles is to have faster motors, which can be reduced in weight and consume less energy as the speed of the motor increases, said Dr. Guoyu Chu of the team. Therefore, this is conducive to improve and reduce costs and improve the battery life of electric vehicles. He said the new motor has reached 100000 revolutions per minute and has a peak power density of about 7 kilowatts per kilogram.

The electric motor system is scalable and can adjust power and speed, and it will take about 6 to 12 months to adapt the electric motor to Tesla electric vehicles, Dr. Chu said.

CTOnews.com learned that the output power of the motor is determined by the product of torque and rotational speed, and when the output power is constant, the higher the speed, the smaller the torque of the motor. The torque can be divided into the radius of the motor and the force applied to the motor. when the force applied to the motor is constant, the smaller the torque is, the smaller the radius of the motor is, and the smaller the motor can become.
