Abstract

An electronic control system has been developed for a small snow thrower for general home use. The new system provides stable propulsion and smooth turning. Development focused on the major requirements of snow thrower stable behavior in changing conditions and responsiveness to operator input. The new system has eliminated the need for troublesome speed control, and even complicated turning maneuvers can be conducted more easily. Both high torque and high speed are required from the drive motor, which employs a 12V battery power supply. A brushless DC motor was utilized and flux-weakening control was adopted to enable these requirements to be balanced. The new control system has enabled the achievement of good performance, and integration of components has resulted in a 10% reduction in the volume of components for the former medium hybrid snow thrower.
