It can be seen that its speed regulation range is 3 times. However, because the constant power speed range of DC motor is fixed, the lowest speed of full power, i.e. rated speed of 100 rpm, is too high, which can not meet the application requirements. In order to obtain high power at lower speed, gear speed change mechanism must be added to expand the constant power speed range.
