3. Project characteristics
•
•
Analysis of common induction motors shows that magnetic field allocation is not optimal.:
Magnetic field of common winding
Magnetic field of combined winding
Computer modelling and experiments allows to determine ways to improve motor characteristics.
•
Project perspectives
Designing of new motor magnetic core.
•
•
•
Common motor
Combined windings
Perspective motor
To design new motor we need
software, computing server and
equipment (1 000 000 $).

4. Induction motors with combined windings for electric vehicle
•
•
•
•
•
•
Combined windings provides high torque, efficiency, power density, low cost and rejection of expensive materials.
The principles of winding schemes designing are patented in Russian Federation. Most part of the designs now in
the stage of patent pending. We planning to obtain from 50 to 100 patents.
We have an Russian Federation patent for electric vehicle with induction motor with combined windings.
Technology tested 18 years on thousands of motors common industrial execution with different powers, rotating
speeds and supply frequency.
Effectiveness of technology is guaranteed by testing protocols of Russian and European labs of manufacturing
enterprises and science institutes.
Drives with combined windings more than 2 years successfully passes pilot operation as part of different electric
vehicles.

6. Drive for trolleybus
•
Trolleybus with drive with combined windings successfully passing running tests in Ukraine, Kiev on «Киевпастранс». (Kiev
passenger transport depot.)
After test passing will be decided on it’s mass application.

7. Electric car Таврия-электро, Russia, Gubkin

9. Subaru Impreza – electro. Odessa, Ukraine
Equipped weight - 1300 kg
Acceleration time to 100 кмч - 12.3 second
Induction motor with combined windings, weights 29 kg.
Power consumption in city mode of drive - 140 W*h/km
Maximal speed - 170 km/h.

10. On-board charger
•
Prototype of onboard charge of 2.4 kW. It’s provide flexible and adaptive charging algorithm for any type of
battery's. In this device we used unique planar transformer. Power module is unified and used in on-board DC/DC
converter of 14 V. Few chargers successfully passing testing on electric cars.

11. Prototype of quick charging station
•
We developed a module charging station. On it’s base it is possible to build quick charging station of more than 12
kW. Sample working in Kiev for 1,5 years.

BMS controls charging and discharging processes. At last charging stage device made balancing for cells. BMS made ​modular. It
consists of one main module A11031 and several additional modules A11032. Additional modules can be up to 63 pieces.
Each module serves 3 or 4 cells. For example for serves 11 cells we need one A11031 and two A11032 in 4+4+3 configuration.
All modules communicate via digital serial data bus.
Balancing current is 700mA.
Boundary voltages are set programmatically from 2V to 4.2V.
Charging controls for two ways:
Via embedded mosfets. Max current is 30A.
Via external relay that connected to Relay2 output.
