RESEARCH & DEVELOPMENT
but for this the focus was on ultimate performance, accepting
that the machine would be more demanding to manufacture in
anything more than smaller batches. In those terms, it is like an
F1 or Formula E unit. "
" It's small and weighs just 41kg, including the 13kg inverter. It is
a 2x 3-phase motor, so its current is shared across two inverters,
a necessary approach to meet the phase current demands at
'normal' DC voltages at this extremely high power level. Both the
motor and inverter have extremely high power density. "
" We needed an architecture that minimizes losses and the
heat generated, especially at high-speed, and that meant quite
a change in the way the motor was wound, since minimizing
resistance losses results in a very low inductance machine. The
switching in the inverter can generate lots of noise and harmonics
and this is more challenging with a low inductance motor. The
software team did a great job developing a new way of controlling
the phase currents in the SPX177 motor. "
Scaleable Core Technology at Helix is based on its proprietary
permanent magnet rotor designed for maximum magnet flux
density to generate maximum performance at minimum weight.
Patented rotor cooling is achieved by using strong magnets but
with low heavy rare earth content. Key features include high
pole-count with minimum ripple torque and high continuous
rating and smoothness. Proprietary winding in construction is designed
for durability under voltage, thermal and vibration stress.
Carbon composite magnet containment supports the high-speed
rotor and high power.
In 2021, Helix moved into its new state-of-the-art Technical Centre
at Shenley Wood, Milton Keynes. The 47,000 sq ft facility was
built to house the company' expanding e-drive business.
