| The Altra EV was engineered at the Nissan Technical Center in Atsugi, Japan, and designed to combine the versatility of a minivan with the environmental benefits of an EV. The four-passenger Nissan electric sedan is as roomy inside as any minivan, and does not have the clumsiness of layout that many other engineer designed electric cars exhibit. Altra was designed for people of American stature, and has room for the things we lug around with us. The styling matches future trends where tall and functional outweighs low and sleek, yet it is designed with aerodynamic efficiency in mind, and has a smooth exterior. The Altra EV is equipped with a permanent magnet synchronous motor and a 32-bit high-speed RISC (Reduced Instruction Set Computing) motor controller processor: The motor features a compact design; yet, it generates maximum power of 62 kilowatts or 83 horsepower and maximum torque of 117 ft-lbs. The unique magnetic circuitry and lightweight design (approximately 85 pounds) of the Altra EV motor make it possible to achieve a high overall energy efficiency of approximately 90 percent under ordinary driving conditions. Because the motor is capable of operating at an ultra-high speed of 13,000 rpm, it was possible to reduce the motor weight 40 percent compared to conventional induction motors. |
