Have you ever experienced this? Loud riding noise, slow acceleration, jerky movements, and erratic battery drain—even when the remaining battery is displayed, it may suddenly lose power during your commute. Toursor solves these problems by choosing a sine wave controller to integrate into its electric scooters, bringing a new riding experience to urban explorers.
Sine Wave vs. Square Wave Controllers: Technical Analysis
Electric scooter controllers are mainly divided into two categories: sine wave and square wave. Their main difference lies in the current output mode:
Sine wave controllers provide continuous, smooth current (similar to an AC waveform), minimizing the sudden current changes during the motor commutation process. This achieves seamless speed transitions and silent operation.
Square wave controllers use staggered, step-by-step current output, which causes sudden changes in torque, resulting in motor vibration, noise, and uneven acceleration.
Five reasons why Toursor scooters use sine wave technology
1. Quiet operation, unmatched smoothness
Sine wave controllers reduce operating noise by 30-50%, eliminating the mechanical hum common on traditional scooters. Riders consistently describe the acceleration experience of the Toursor as "effortlessly smooth - like gliding on ice", making it ideal for noise-sensitive environments such as residential or indoor areas.
2. Improved efficiency and longer range
Our controller uses a FOC (Field Oriented Control) algorithm to optimize energy distribution and minimize unnecessary power consumption. Compared to square wave systems, Toursor's sine wave technology can increase battery efficiency by 10-15%, allowing for longer rides and fewer recharges.
3. Precise control, safer riding
Say goodbye to sudden bumps! Sine wave controllers provide linear throttle response, ensuring real-time synchronization between acceleration input and motor output. This eliminates the "lag and surge" effect of square wave controllers, while built-in safety features such as overload protection and automatic braking further ensure rider safety.
4. Durability
Toursor's sine wave controller features an IP67-rated waterproof design (fully sealed design) and an aluminum chassis heat dissipation system to ensure stable operation even in rain, dust or extreme temperatures. No more worrying about performance degradation on rough terrain!
5. Environmentally friendly and compliant with regulatory requirements
Our controller is designed to meet European standards, with extremely low electromagnetic interference (EMI) and operating noise below urban noise limits, easily meeting CE certification standards. In addition, its energy-saving design also meets the sustainable development values of environmentally conscious riders.
