Re: [EVDL] EVLN: Halbach near-monopole e-motor> Focused Magnetics
What a bunch of baloney. If a motor is already 95% efficient, how do you double its efficiency? I'm sure the motor gurus on the list can shoot holes in this nonsense. There are reasons motors haven't changed much in 100 years. One, there isn't much room left for improvement, two, the laws of physics.

February 01, 2018 Mil Arcega [image https://gdb.voanews.com/1D51C300-4BED-48EF-87B8-4B9596EDD5F5_cx0_cy7_cw0_w1023_r1_s.jpg Roberto Catalan, inventor and CEO of Focused Magnetics says his new electric motor can beat your electric motor. (M. Arcega/VOA) ] If Nikola Tesla, the legendary genius who invented the electric induction motor were alive today, he would no doubt be disappointed. That’s because the majority of electric motors we produce today (including the one that powers his namesake 2017 Tesla Model S), remain fundamentally the same as the one he patented in 1887. So much for progress. The Stakes are Big For those of us alive today, that’s not a good thing. Here’s why: half of all the electricity in the world is consumed by electric motors. Combined, these motors consume about 9,000 trillion watt hours (terawatts) of energy each year. Improving the energy efficiency of the world’s electric motors by just one tenth would save enough electricity to run the entire country of Japan for an entire year, dramatically reducing the world’s carbon footprint and cutting harmful CO2 emissions by nearly a billion tons. Now imagine if the technology to make electric motors nearly twice as efficient were already here. Robert Catalan, founder and CEO of Focused Magnetics says it is. Wearing an impish smile that never seems to leave his face, Catalan looks more Buddhist monk than genius. But it is the belief for what his new invention can accomplish where this mild mannered engineer’s true motivation shines. Turns out, deep down, he just wants to save the planet. The Solution Intrigued, I agreed to meet Catalan in a quiet urban park just outside Washington, D.C. There he unpacks a wooden crate revealing a tire-sized contraption that looks like something out of Star Gate SG-1. He says the prototype motor represents a breakthrough technology that effectively doubles the power and efficiency of any device that uses a conventional electric motor. Before explaining how, he offered a primer on how conventional motors work: “Electric motors have two basic elements. One is the part that rotates (the ‘rotor’) and the other is the part that doesn’t move (the ‘stator’). But it’s really the space between the rotor and the stator (i.e. the air-gap) where the work of an electric motor takes place.” Because conventional electric motors use magnets and electromagnets with equal polarity (i.e. 50% north pole and 50% south pole), Catalan says half of the magnetic energy is always directed away from the air-gap, leading to poor utilization of available energy. Who is Klaus Halbach? Catalan’s quest to utilize available energy efficiently led him to investigate the work of Berkeley physicist Klaus Halbach. In 1987, Halbach discovered that by orienting permanent magnets a certain way, he could focus nearly all of the magnetic field to one side. In doing so, Halbach had discovered a way to create ‘near-monopole’ magnetic fields, meaning that approximately 97% of one pole is enhanced, while the other pole’s magnetic field is reduced to about 3%. The phenomenon is known as the “Halbach Array” (and even has its own Wikipedia page). A handful of companies have successfully applied Halbach’s permanent magnet arrays to enhance the power of their rotors. But their electromagnetic stators remained unchanged. Unlike permanent magnets, electromagnets cannot be oriented in a Halbach sequence because the copper wires create a physical and energized barrier that prevents magnetic forces from combining to form a near-monopole field. Catalan says he has overcome that physical hurdle and was recently awarded three U.S. patents along with several international patents currently pending for the electromagnetic version of a Halbach array and its various applications in motors and generators. Achieving Near Monopole Magnetic Fields Catalan says conventional motors are a bit like incandescent bulbs. Like photons from a light source, electric motors wastefully radiate magnetic energy in all directions. Catalan says his motor is configured to act like a laser, focusing nearly all the magnetic energy exclusively towards the airgap to enhance power and efficiency. By harnessing this ‘near-monopole’ energy, Catalan says an electric vehicle using a production version of his new motor would travel nearly twice as far as a conventional motor on the same set of batteries. Conversely, his motor in its final form would provide nearly twice as much power or torque as a conventional motor using exactly the same amount of energy. There are other advantages. Halbach arrays don’t require the additional metal (known as back-iron) that conventional motors need to function. As a result, ‘Catalan motors’ are lighter. Additionally, because the polarity of the patented electromagnetic array can be manipulated, both sides of his stator’s surfaces

Tesla racing championship Electric GT gets green light from FIA after Model

]
As we recently reported, the Tesla racing championship Electric GT is still
alive despite a crash and several delays.
Now, the company has received the green light from FIA after their modified
Model S P100D passed crash tests.
Electric GT announced today that its racing championship, now called the
Electric Production Car Series (EPCS), has been officially sanctioned by the
FIA, the governing body for world motorsports.
The company first planned to launch its championship with the Tesla Model S
P85+, but they instead decided to use the Tesla Model S P100D with
‘Ludicrous+’ after it was announced. They claim that a stripped-down
racetrack-ready Tesla Model S P100D can accelerate from 0 to 60 mph in 2.0
seconds (0 to 100 km/h in 2.1 seconds).
The change turned out to be a good decision since they ended up crashing
their original Tesla Model S prototype race car during testing – pictured
above.
As for their modified Model S P100D, they claimed that they reduced the
weight by 1,100 lbs with biocomposite and by stripping the interior.
The new vehicle has now passed the FIA crash tests for approval. Here it
experienced a frontal collision against a rigid barrier – a block of
concrete that weighs 130 tonnes covered with a 19mm wooden plate – at a
speed of 14 m/s (50.4 kph):
The vehicle was supposed to debut at their first official race in November,
but it was delayed and instead replaced by a “Day of Light” event during
which they made several announcements and unveiled the supporting events
around their championship, like a virtual reality race and e-kart race.
But now with FIA’s approval, they say that they can move forward.
Electric GT CEO Mark Gemmell said:
“This is such an exciting day for us as we confirm that the Electric
Production Car Series has been officially sanctioned by the FIA. We respect
the FIA and we are honoured to have their support ahead of our inaugural
season.”
They released all the rules and regulations of the series for the 10 teams
and 20 drivers. Here’s a quick summary of them:
“Electric GT Holdings Inc. has also published the EPCS sporting
regulations, which include a three-heat (585kW) qualifying format. Rounds
will include a day race (60km) and a dusk race (60km). EPCS race power will
be set to a maximum of 585kW (778hp).
An innovative “Drift Off” competition will also take place at suitable
circuits, where fans will see the top two finishing drivers plus two
fan-voted drivers go head-to-head to complete a series of drifting
challenges to secure three further championship points.”
558 kW and 300 kW.
The company has released an updated calendar yet, but we expect to have more
information soon.
Electrek’s Take
It could be an exciting electric race series, but it looks like their
troubles and delays might have lost them the first mover advantage.
Of course, Formula E has been doing well for a while now, but Jaguar is now
also launching an all-electric race series using new I-Pace with Formula E.
I am glad that they are moving forward, but I won’t hold my breath until I
see those 10 Model S P100Ds on the starting grid.
