The word’s best rare-earth electric machine
Scroll to learn more about the difference that a Jacobi Variable Flux Memory Motor (VFMM) can make
The world market for electric motors will be
$186B
by 2027
These motors are responsible for almost half of the world’s power use
Motors are in just about everything
Efficiency is hugely important
In fact…
Improving average efficiency by just 1% would unlock the equivalent of
1.6 years of New York City’s electric power use!
The thing is…
Highly efficient motors have required magnets made with high rare-earth material content, the bulk of which is controlled by China. This is an expensive supply chain risk.
Fortunately,
other solutions exist to avoid the need
for these rare-earth materials
there is an Industry-Wide Push for Rare-Earth Free Performance
Unfortunately, EFFICIENCY IS SACRiFICED
The Jacobi VFMM Difference
Traditional motor technologies are locked into fixed efficiency zones
—optimized for only one operating condition, and compromising elsewhere.
Jacobi VFMM technology dynamically shifts the efficiency zone
—align with real-time performance demands for peak efficiency
The Result?
One motor that adapts like four
From launch to cruise, uphill to regen, VFMM delivers the performance of multiple motors
We’ re showing that you don’t have to rely on rare-earths to achieve high performance, high efficiency, and high power density

Some say it is science fiction…
“In an ideal brushless drive, the strength of the magnetic field produced by the permanent magnets would be adjustable. When maximum torque is required, especially at low speeds, the magnetic field strength (B) should be maximum – so that inverter and motor currents are maintained at their lowest possible values. This minimizes the I² R (current² resistance) losses and thereby optimizes efficiency. Likewise, when torque levels are low, the B field should be reduced such that eddy and hysteresis losses due to B are also reduced. Ideally, B should be adjusted such that the sum of the eddy, hysteresis, and I² losses is minimized. Unfortunately, there is no easy way of changing B with permanent magnets.”

“A large portion of the time people spend driving is in low-torque highway situations. However, there are a lot of motors that offer great 0-60 MPH performance but are very inefficient in the low-torque highway-speed regions. So the question is, can I have everything – both high efficiency and high performance? The answer, unfortunately, is no. But you can make intelligent choices between things that are competing with each other.”
-Konstantinos Laskaris, 2016, Tesla Motors

in the lab, on the track, and in the field
