Quantum Electric Ltd is proud to introduce modular electric
motor and generator with a wide efficiency range.
This is achieved with multi phase speed controller technology
associated with 'Electric gears' (EG).
The new EG speed controller technology is practical for all
electromagnetic motors and generators.
The introduced Electric Gears technology includes:


Wide Efficiency Range Technology (WERT)
Universal Voltage Operation (UVO)
Modular Multi-Phase Operation (MMPO)

The prototype synchronous permanent magnet motor was used
for measuring and testing Modular Multi-Phase Operation with
Electric Gears. It has:


rotor with twenty permanent magnets
six sets of modularly replaceable phase coils on an axial flux
configuration
For tests, it was connected first for 3-phase operation, and next for 6-phase
operation for
comparison.
For experimental
optimization, this
modular motor
was built to allow
all parts related
to magnetic flux
to be either
easily changed or
adjusted.

Prototype motor stators were built as two independent 3-phase
modular coil sets in front of and behind the rotor.
The motor frame was built to allow rotating these two 3-phase coil
sets so that their phases overlapped to create a 6-phase drive for
Modular Multi-Phase Operation measurements.
Because no 6-phase ESC were yet available, the measuring
prototype was realized with two separate standard 3-phase ESC's,
each controlling one of the two coil sets.

It is known that electrical components connected into
series, parallel or combination of those behave differently
in the sense of energy consumption and output power.
In a traditional control systems
where conventional frequency
converter or electronic speed
controller technology are used this
leads to a very limited efficient
rpm-range of modern electrical
drives.
A method to change connections between other basic electromagnetic
components during drive facilitates a totally new electric gearbox
technology with no rotary or moving parts for that purpose.

Electric Gears Technology
The usage of electrical connections to adjust motor or generator
performance is called 'electric gear' or 'electric gears' (EG).

Using connections of segmented phase coils or sets of phase coils to
electrically extend motor or generator range of optimal efficiency for
significantly wider range of power and rotational speed.
The 'electric gears' operate completely electronically without any
moving mechanical parts, which EVT and similar gearboxes still have.
The “shifting” is realized by utilizing a modular construction of an
electronic speed controller so that each module electronically
switches interconnections of phase coil segments of a motor or a
generator.
EG do not increase the maximum torque of an electrical drive, but
control the output power directly.
EG function allows to shift “gears” smoothly and automatically during
full power drive, without any need to reduce power for clutch and
gears operations required with traditional mechanical transmission.

Heat Resistant Winding Allowed

This new property is realized by modular coil architecture, which
allows using flat wire or even foil materials for very effective heat
dissipation from inside the winding.
Flat foil windings allow using high temperature resistant insulation,
making modular coils resistant to unusually high peak temperatures
for handling repeated high acceleration peaks.
Ruggedness in overload situation makes modular coils ideal for
regular intensive acceleration in the case of different vehicles, working
machines and aircraft.
The possibility of applying a stronger current compared to traditional
electrical motors.

The prototype was investigated both experimentally and using
modern numerical methods.
The first approach focuses mainly on circuit variations, current,
speed ranges and testing different materials.

Each costructive variable is studied using private program code and
virtual experiment.
The aim is to improve magnetic flux density in the core.
