Sine Wave Brushless Controller
1) Low system noise: Load 100 kg, silent room test is less than 52 dB;2) Small volume of motor: The manufacturing process of servo motor is designed, it is small in size and the motor is 80 cm in diameter, which means it takes up very little space;
3) Light weight of motor: The total weight of a single motor is about 2.9 kg, making the total weight of the finished product even lighter;
4) Loud speaker: The volume is up to 108 dB, and the sound is rich and not harsh;
5) Comfortable driving: The sinusoidal vector control method uses the linear hall sensor and the algorithm to correct the Angle to ensure the control is more accurate.The control box will receive speed and steering feedback to ensure optimal motor performance, making the wheelchair more stable and safe to ride in any environment;
6) Drive at low speed: It can walk slowly at a speed of 0.1 km/h, making it convenient for the wheelchair to travel in a narrow space;
7) Speed closed loop: The change in battery charge had no effect on the maximum speed of the wheelchair (The maximum speed of the 12-inch wheel can be adjusted to 8 km/h, and the factory set the maximum speed to 5.8 km /h);
8) Electromagnetic brake shutdown time adjustable function: Delay the closing of the electromagnetic brake for 10 s to avoid frequent closing of the brake, reduce the noise of frequent opening and closing of the electromagnetic brake, and extend the service life of the electromagnetic actuator;
9) Electronic brake function: When starting again after stopping in the middle of the ascent, avoid slipping, and use with electromagnetic brake when descending, double guarantee safety;
10) Power limiting function: According to the discharge characteristics of lithium battery, discharge current limitation is carried out to extend the battery life;
11) Expandable putter function: Extensible electric push rod for 2 or 4 way control, the controller can switch between driving and putting modes at any time, the wheelchair user can adjust the position of leg support and backrest with one click, which is easy to operate;
12) Safety protection function: It has the protection functions of emergency power cut off, motor missing phase, broken line, over current, over voltage, under voltage, over load, over heat and so on.
