Linear Labs’ HET electric motor is 2-3 times more powerful than any other motor

Since we have been dealing with petrol and diesel engines for so many years, in the future this will be the case with electric motors. Often, many companies speak about their electric motors, which should generate a much higher torque density, measured in kilowatts per kilogram, than their competitors – and are not stingy with superlatives.

Now, Linear Lab announced the development of the Hunstable Electric Turbine (HET) electric motor, which promises twice the torque and three times the power of any other motor of the same size and with the same energy consumption.

The electric motor was developed by father and son: engineer Fred Hanstable, who designed nuclear power plants, and Brad Hanstable, who helped create the Ustream streaming service, sold by IBM in 2016. The new electric motor promises to revolutionize electric vehicles.

Initially, Linear Labs decided to create a linear generator that could generate sufficient power from a low-speed rotating shaft – a windmill or a water wheel. The development has received 25 patents and has been very effective.

In a magnet-driven electric motor, one component rotates inside another. To create more torque, you need to apply more energy to the engine or create a larger motor. Linear Labs found a different path: combining axial and radial flows in one engine.

In simple words, HET is an electric installation with four rotors rather than the regular single unit. The central rotor rotates inside the stator, creating one source of torque. Meanwhile, the second rotor rotates outside the stator, creating a second source. Two additional rotors are located at different ends of the stator – in fact, these are two concentric radial engines with two axial.

The HET has four rotors, which help the coils of the engine to rotate.

As a result, HET develops a torque that is several times greater than that of electric motors of comparable size and power consumption. In addition, Hunstable Electric Turbine uses 30% less copper to produce. The design also eliminates the end windings that lie outside the stator, generating heat.

Linear Labs invented a turbine that doesn’t need to spin so fast to make enough power and torque to drive a vehicle. Hence, Father and son decided to eliminate the gearbox to reduce weight, cost, and complexity. It also eliminates the AC-to-DC converter, again reducing complexity, cost, and weight. It also offers the possibility of a larger battery, while reduced weight improves handling and acceleration of the vehicle, which means that it enables excellent performance.

Linear Labs has already signed agreements for the production of its “turbocharged” electric motor: with a scooter manufacturer, with the Swedish company for the production of electric drive systems Abtery and with an unnamed company developing a hypercar, which is due to appear in two years.
