Although electric cars are almost everywhere around us, the technology that powers them, whether it is batteries, engines or other accessories, is far from perfect. This is why many old and new companies are working hard to improve this technology.
As early as March, the British equipment manufacturing company Equipmake announced that it would cooperate with another entity company called HiETA to carry out the Ampere motor project to produce the world's largest power density permanent magnet motor.
Six months later, with the advancement of the 3D printing Ampere project, Equipmake announced that it has two electric motors ready. It is said to be the world's most mass-produced electric motor with the highest power density, which can be used in any equipment, from off-road machinery to mining equipment And agricultural equipment is also used in some automotive industries, such as super sports cars or electric buses.
Among them, the first electric motor is called APM120, weighs only 14 kg, and can obtain 125 kW (168 hp) peak power at 12,000 rpm. In addition, the continuous power is 75 kW and the peak torque is 130 Nm. The calculation shows that the power density is about 9 kW/kg. The second electric motor is more powerful, called APM 200, weighs 40 kg, and can obtain 220 kW (295 hp) peak power at 10,000 rpm. In addition, the continuous power is 110 kW and the peak torque is 450 Nm. The calculation shows that the power density is about 5.5 kW/kg.
"From electric buses to super sports cars, the APM series of motors will bring significant improvements to the efficiency and performance of our automotive customers' products." Ian Foley, managing director of Equipmake, said: "These motors have the same advantages. It can provide high power density and low weight, coupled with the extremely compact design of integrated components such as inverters and gearboxes, which are also suitable for the mining industry.
