From the view of torque controlling strategy, the relation between the torque controlling strategy such as the electric current feedback method国产一级婬片A片AAA小视频、 PWM open loop method etc and the vehicle driving way is analyzed firstly, then the conclusion could be drawn that the PWM open loop method has more advantages than the electric current feedback method when they are both used in the same vehicle which is direct driving by hubcap motor. Secondly, based on the electric motor mathematic model and its experiment, a new permanent brushless dc motor phase electric current detector method in which a digital signal processor and single current sensor are used is introduced.
