Electric Vehicle Motors (PMSM)

Over the years, Indian automobile industry has grown and took a quantum jump from local to global market but due ecological impact of petroleum extraction and restricted efficiency of internal combustion engine, electric vehicles are substituting traditional vehicles. To a certain extent electric vehicle working is different from conventional internal combustion engine vehicle as transmission of electrical energy into the kinetic energy is taking place from battery to electrical motor to wheels. In order to fit in cost effective solutions, optimized design of powertrain i.e. charger, battery, controller and electric motor is the biggest challenge. A good electric vehicle design addresses the characteristics like aerodynamics, overload capacity, power density and vehicle weight without negotiating the performance and driving experience. Small size electric vehicle with high power density and light weight determines the speed, torque and power rating of motor electric motor used in powertrain. Advanced power electronics and controller technology has made it possible to design and develop various electric motor meant for powertrain.
A key challenge in design and development of electric vehicle powertrain motor is to maximize power and torque density at lowest weight, volume and cost. In early stage of electric vehicle development, DC series motors were used in powertrain owing to its high starting torque, easy speed control and capability to sustain sudden increase in load. With the time brushless DC motors with permanent magnets are evolved and left behind the use of conventional DC motors. Due to high cost, limited overloading capacity and restricted thermal capability brushless DC motors are best suitable for bike, scooter, mobile robots, wheel chair, medical stretchers, lawn cutter etc.
21st century electric vehicle expended its horizon from truck to ship to train to aircraft that demands a complete innovative design and development approach of powertrain. AC motors such as permanent magnet synchronous motor (PMSM) and induction motor (IM) qualifies the requirement of high power density, increased efficiency, regenerative breaking, less maintenance, superior thermal management, compact size and great reliability for new era electric vehicle. Permanent magnet synchronous motors are the paramount choice for higher models of car, bus and truck because of superlative efficiency compared to induction motors.
KONMOS make electric vehicle and hybrid vehicle motors (PMSM) are designed and developed including but not limited to two wheeler, three wheeler, tractor, mini truck, mini bus, rickshaw and load carriers. Small and medium rating motors are designed considering the need of local and global industry. Wide range of efficient and cost effective solutions for various electric vehicle type ensures the optimized performance. Indigenous design, development, testing and manufacturing of electric vehicle and hybrid vehicle motors (PMSM) contributes to ATMANIRBHAR BHARAT ABHIYAAN and helps to make India as a preferred destination for production of automobile.
