Ac Motor Speed Controller Arduino

Only one thing left the motor speed controller.

Ac motor speed controller arduino. This pwm signal will decide the amount of voltage output to the ac motor which in turn controls the speed of it. The complete code of this arduino ac fan speed control project is given at the bottom of this. To gain control of the speed of your motor whenever you need it you need to add a potentiometer to your circuit. The en a pin of ic is connected to the pwm pin 2 of arduino.

But dimming action with ac appliances is not that easy it demands knowing some theory. In this present article we only restrict ourselves to discussions around esp32 arduino ac motor speed control module and circuit. These two digital pins of arduino control the direction of the motor. The mst k07 permits to control an ac universal motor brushed motor maintaining the rotation speed when the load changes.

Without it the motor will spin at it s maximum 15000 19000 rpm. To control the motor peed we could use a scr voltage regulator but at low rpm the motor will be weak with no torque. To set the values of arduino pins 8 and 9 we have used the digitalwrite function and to set the value of pin 2 we have to use the analogwrite function. It s too much for wood lathe.

Using an ac appliance for switch on and off quite easy by using an usual mechanical relay or a solid state relay. The arduino pro mini is used to store motor controls pid algorithms and to communicate with the pc through com port. This regulator is full suitable with wash motor such as mc3064. The same motor i had in my workshop.

The computer should have hmi made by visual studio to communicate with arduino. To do it it is needed that the motor has a speed rotation sensor. Here a bt136 triac is used which controls the ac voltage as it is a power electronic switch for controlling an ac voltage signal. It controls the torque of the motor.

A 10k ohm variable resistor. Hmi will show motor speed graphs and change motor speed settings.
