At the core our the N1S sits the BOSCH developed 2400W Motor.The NIU proprietary Field Oriented Control* delivers the ultimate driving experience.
This mash-up of technology and hardware strikes the perfect balance of performance and power consumption.
*Field Oriented Control is abbreviated as FOC below.
Extending the ride and performance
In real-time, the FOC is monitoring the overall electricity demand on the system so that the BOSCH motor performs at a peak level while efficiently using the resources available.
In an effort to enhance overall vehicle performance the Electric Brake System (EBS) and FOC optimize power conservation and output; effectively recycling power during certain periods of braking and limiting power output during select periods of acceleration.
We have effectively been able to reduce braking distances by up to 60%, and recycle 6% of the battery capacity back into the system through our intelligent braking system.
We have collaborated with BOSCH to develop the N1S motor. With 120 Nm of torque at its disposal, the N1S provides the “get-up-and-go” you need to feel safe on a car dominated road. Couple this with a 2400W power output to easily reach a top cruising speed of 45km/h.
BOSCH’s state-of-the-art motor technologies is a key component in optimizing energy efficiency simply by reducing motor abrasion and the power wastage that can be found in your typical motor. When compared to typical motors under the same driving conditions the N1S motor is performing at least 10% more efficiently.
The NIU FOC (Field Oriented Control) system was built in collaboration with BOSCH to create a state-of-the-art power train. Striking a fine balance between performance and energy consumption, the FOC is key in balancing range and speed.
You can think of the FOC as the brain controlling the motor in real-time. It recognizes the conditions your riding under and instantly calls on the motor to perform as optimally as possible. The FOC can sense the scooter diagnostics, things that you as a driver cannot see, and make a decision as how the motor will respond to your riding demands.
Our FOC taps into the performance of a vector controller, which is far superior to the standard square-wave controllers on the market. When people get off the bike after their first or fiftieth ride, they always say, “I cannot believe how smooth a ride the scooter is.” It’s the FOC that makes this experience and follow-up comment possible.
The NIU brakes are engineered from a high-manganese steel composite, lubricated with BOSCH brake fluid, and threaded brake line to extend the life of the entire system.
Not only is the EBS making your ride more safe, it is also recycling energy back into the system. On average the EBS is providing an additional 6% of battery power, or in other words about 4km of riding range.
