The DC motor was often used in various fields, from the industrial field, domestic equipment even the child's toy. The capability pursued set point and the keep of the motor speed when the load is changed are the performance parameters of the control speed quality. Microcontroller technology and PWM enabled us to make various digital control with the large computation capacity but consumption of the power is low. Fuzzy logic was one of the artificial intelligence methods that connected the language and the capacity thought humankind. Fuzzy logic enable us to design of the control system without used plant modeling that was complicated but get good result. The plant of the motor DC speed controll implemented in ATMega 8535. The speed censor used magnetic encoder and to generate voltage using PWM thas was feature of ATMega 8535. Triangle input membership function are E (the difference seting point with the speed) and CE (the change in the difference error the speed) and singleton output membership function is &#61508;PWM (the change the PWM value). The analysis of implementation showed that the sistem capable to compensate when the load and power supply is changed and so the set point can be maintained. <br />
