NEMA 24 stepper motor with best-in-class power density

Permanent magnets between the stator teeth make Nanotec's SCB6018 with 60-mm flange a smooth-running -- yet powerful -- stepper. FluxFocus technology guides the entire magnetic flux into the stator teeth. This prevents flux leakage and provides more torque across all speeds. This motor generates a holding torque up to 3.6 Nm. Combined with a closed-loop controller, the SCB6018 is ideal for use in valves and textile or other applications that require rapid acceleration over a short distance.

Nissan develops twin-motor all-wheel-control technology for electric vehicles

Nissan says it is elevating the performance capability of all-electric vehicles with its new twin-motor all-wheel-control technology called e-4ORCE (pronounced "e-force"), which provides instant torque to all four wheels to deliver balanced, predictable power and handling on par with many premium sports cars.

"The e-4ORCE twin-motor all-wheel control technology offers precise handling and stability, which gives drivers greater confidence and even more excitement than ever before," said Takao Asami, Nissan's senior vice president of research and advanced engineering. "This technology enables excellent cornering performance, traction on slippery surfaces, and a comfortable ride for all passengers."

The technology was born from lessons learned in the development of the Nissan GT-R's ATTESA E-TS torque split system and the Nissan Patrol's intelligent 4X4 system. Engineers developed the e-4ORCE technology to specifically manage electric vehicle power output and braking performance to be smooth and stable.

Nissan says unparalleled ride comfort is the result of the e-4ORCE technology's ability to minimize vehicle pitch and dive. This is accomplished by employing regenerative braking from both front and rear motors, making city stop-and-go traffic less jostling. Similarly, on rough, bumpy roads and when accelerating, motor control is optimized to maintain ride comfort by minimizing irregular movement.

e-4ORCE increases driver confidence by faithfully tracing the driver's intended line thanks to ultra-high-precision motor and brake control. With the confidence to handle such a variety of road surfaces, even for novice drivers on slippery surfaces, driving becomes more enjoyable -- or so that is the aim.

Nissan displayed its zero-emission crossover Ariya Concept, which features e-4ORCE technology, at the huge Consumer Electronics Show in January and also showcased the tech on a twin-motor, all-wheel-drive test car in Las Vegas during the event.
