Design of a Direct Sliding Gearless Electrical Motor for an Ergonomic Electrical Wheelchair
The use of the electrical wheelchairs designed for the disabled people should be easy and flexible. A brushless DC motor with a permanent magnet that can operate without gears was designed to be used in an ergonomic electrical power supported wheelchair. This motor will be placed within the hub of rear wheel with standard diameter of the wheelchair and it will have the capacity of producing high torque at low speed. The stator structure of the designed motor, its physical measurements and features, appearance of its iron sheet package, its mesh production, magnetic flux intensity, and flux lines and performance characteristic values were obtained. The results obtained showed that this new design with low speed and high torque can be an alternative in electrically driven devices and systems.
