Hello iam new here and just needed abit of help..Does anyone know where i can get circuits for motor especially something like food blender circuit with speed controls for the motor sumfin like that tnak you ppl
PS. what is this type of motor called and what can i use to increase and decrease speed aswell as reverse motor.
Thanks man, if anyone else has any more circuits i might need them as iam doing a project where i have to take a few circuit designs and develop them to my final design this is a loong story. basically it is for my coursework Systems and Control: Here is a link if you intrested:
You should be aware that this ISN'T an AC motor speed controller, it's a simple controller for an AC/DC (often called universal) motor, and is basically an incandescent light dimmer circuit.
There are various types of AC motor, but electric drills comonly use the AC/DC type - the food mixer may, or may not?.
Also, there's no external way to reverse the rotation of an AC/DC motor, you need to reverse the polarity of either the rotor or stator (but not both).
As for forward and reverse goes, you will need a DPDT switch. Connect the +ve to one of the center pins, and the -ve to the other center pin.
Now pick an end. Connect the motor wires to it. The other end will have the motor wires connected to it the other way.
Now when you flick the switch, the motor switches direction instantly.
As for speed control, you can either use a 100 ohm potentiometer, or play with the voltage. Just make sure the voltage does not exceed the maximum voltage rating for the switch or the motor or one will malfunction.
That only works for a DC motor! (and only for permanent magnet ones!), a food blender is more likely to have an AC motor.

Some good issues....I got like two circuits i need two more....iam finding it hard to find a circuit for my blender device...all i can find is simple motor circuits i need mains voltage and speed control thats about it to power a big motor therefore the circuit should be simple, on/off swtich..speed control....some safety trigger...reversing the motor no big deal i can live without that as there is not much use in blender which way it goes just a thought...

Man i tried all the sites iam struggling on this, basically my task is to investigate electronic controls and drive mechanisms for food blenders, types of switching and variable speed controls, thats why i think i need a speed control circuit for the motor or some kind of switching circuit :cry: ...Therefore i think the circuit must be simple nothing complex it is for my A levels if people know what that is here in England. :wink:

That's the thing!, there is no 'standard' blender - the phase shift circuit posted earlier will work for an AC/DC motor - and is probably the only simple after market speed controller that's practical.
