The invention provides a motor controlling device of electrical fishing line reel capable of not reducing the performance of the fishing line reel and preventing the motor being burnout, comprising a brake unit (90), a winding reel sensor (102) detecting the rotating speed of the winding reel； a current detecting portion (108a) for detecting the load of the winding reel by current value； an adjusting rod (101)； the rotating speed of the winding reel is divided into high and low grades； the adjusting rod sets the speed upper limit value of each grade； a fishing line reel controlling potion (100) for controlling the speed of the motor such that the rotating speed of the winding reel is accordant with the set speed upper limit value； when the state of the motor current is over the first current value, maintaining the first set time； and when the speed of the winding reel reduces less than the first speed, the first motor controlling portion executes first intermittent control to the motor current to interrupt the motor current； the first motor current value is less than the maximum current value of the motor； the first speed is less than the speed upper limit value of the maximum speed grade.
