With deepening economic development and technology, more and more motor controller device to be necessary, in the process of the marketization of the plays an important role in People's Daily life, then we can know about the gear ratio it together: 1, in an internal gear, brushless dc motor controller of two gear running in the same direction; 2, the motor controller in machine of decelerate of hard tooth flank a external gear, it work for you to reverse running, small gear rotating to the right, turn the wheel to left; 3, brushless dc motor controller in a pair of machine of decelerate of hard tooth flank gear running number and inversely proportional to number of pinion revolution more than big gear, the gear ratio, speed reducer gear ratio is different; 4, in a pair of gears, the number of teeth gear pinion, less teeth gear is called big gear, more equal number of cases, the drive gear pinion, driven gear wheel. Gear ratio determines the work efficiency and quality of brushless dc motor controller, so we still need to know about the, at the same time, it's in home appliance, automotive, aerospace, medical, industrial automation equipment and other industries have application!
