Torque controller

详情

The torque sensor is a basic component so that meet the demand of e-bike’s assistance, But for a power type electric bicycle can achieve high safety and comfort, even if has a good sensor without immediate corresponding linear controller, the control motor output power cannot achieve good matching with manpower, Now we speak of so-called controller is already a execute the components in torque sensor electric bicycle. Our controller has the following advantages: 1．Adopted current-mode control as executive components rather than the voltage type, So when pedal torque in different sizes have different output current to be reached the matching with manpower, overcome the voltage type control brings to the current limit of starting always not controlling starting state. 2．Due to without the voltage type control launched big output current problems caused the pre-shoot feeling. Controller has the following advantages: A. can increase the current limit value，so greatly promote the climbing capacity of the whole e-bike. B. Startup when heavy pedal on large output, light on small output, assistant power and electrical can be better matching, so the rider feel more comfortable while it start. C. Improve the safety when started due to the foot strength can controlled smoothly. D. For starting, the current have not to reach the current limit and therefore can achieve the purpose of saves electricity, improving the influence of frequently startup to the endurance mileage in the city. E. Avoid regular high discharge current, impact on the life of the battery will be reduced, so obtain the role of protection battery. 3. Adopted flexible electronic brake technology, make the outage of motor power corresponding time shortens greatly, namely the distance improved in the incident of braking power. 4. Can be used with hall or none: when plug in five core pins for have hall state, when not in five core pins for no hall state. When the hall in the motor damage, be automatically converted into form, so can still be normal used as the hall became bad. 5. The motor with hall, when a motor and matching phase is wrong, When the motor phase angle is not the same (such as **0 degrees to *0 degrees), only vehicle charged condition, pull the plug motor and controller of five core pin can normal match.
