EMF Motor is developing electrical vehicle motor by means of R&D
Hasan Basri Kayakıran, the Chairman of Board of Directors of EMF Motor, emphasized that the R&D efforts of the automotive companies generally focus on electrical motors in electrical vehicle production, and stated that EMF Motor also produces electrical vehicle motors. Kayakıran mentioned that EMF Motor intensely produces for industrial product and lift sector, and continued "Besides, the advancement of the motor technology provides advantages for the producer and the country. Therefore, we focused our R&D efforts on developing vehicle motors". Kayakıran noted that they developed one fully electrical and one hybrid motor in the scope of their R&D efforts, and stated that the vehicle using the developed electrical motor can reach a speed of 120 km/h, and the vehicle using the developed hybrid motor can reach a speed of 50 km/h.
Hasan Basri Kayakıran stated that, with the projects that they carried out, they produced two fully electrical hub motors that can achieve a speed of 120 km/h and two hybrid hub motors that can achieve a speed of 50 km/h, and one final prototype motor. Kayakıran described the specifications and the operation principles of the motors they manufactured, and emphasized that they started out by dividing their efforts for vehicle motors into two main groups. Kayakıran stated that they first worked on regular internal combustion engine principle, and said "With the information we learned from this principle, we developed the main motor and a system that transmits the motion from this motor to the wheels. The motor tests were completed successfully".
Hasan Basri Kayakıran gave information also about the general specifications of the said motor, and noted that EMF electrical vehicle motor provides 10 to 30 percent more energy efficiency. Kayakıran expressed that their locally manufactured products, which provide high torque at low speeds, reduce the need for motor cooling system, and continued: "This product eliminates the need for gearbox, and therefore prevents gear losses. In addition, the possibility of making optional modifications on the motor allows for high motor efficiency at low speeds, as well as easy starting off of the vehicle. The product also has a silent, oil-free and maintenance-free structure thanks to the constant torque coefficient at all speeds."
"We significantly reduced the copper losses in the motor"
Hasan Basri Kayakıran also explained that they also offer the possibility of transmitting the energy to the batteries without gearbox losses with the efficiency and regenerative features of their products; and stated that the torque values in the vehicle can be calculated with high precision thanks to the virtually constant torque coefficient of the motor at all speed values. Kayakıran highlighted that the predictability in battery management system is thus enhanced. Kayakıran underlined that the winding resistances were lowered with the special winding structure of the motor and thus the copper losses in the motor were significantly reduced, and explained that they also reduced the need for the cooling system required by the motor.
Hasan Basri Kayakıran said that the number of poles of the motor can reach 66-88 although the stator windings of the motor have low number of poles, and stated that this patented structure is known as LiProKa motor physics. Kayakıran explained that the copper losses are reduced thanks to the low number of stator poles and low winding resistances, and that this increases the efficiency of the motor. Kayakıran stated that the number of poles achieved is also suitable for low rpm applications, and that it can eliminate the need for gearboxes.
