Hi I'm new here, so please bear with me.
I'm looking to use a step motor to stir a powdery mixture in water in order to keep it from hardening. A step motor seems to be just what I need as it is cheap and has high torque, but I'm having a lot of trouble understanding how to piece together all of the electronics.
I think I need a driver and a micro controller, but I'm not exactly sure how each piece interacts with the motor itself, and why each is needed. I've read a lot of DIY schematics for step motors, but my knowledge of electronics is not enough to understand everything that's going on in the circuits. All the unit will be doing i stirring water, so all I need the motor to do is rotate in 1 direction constantly.
I'm looking to use one of these two motors:
They are both Bipolar, but I'm not sure why one is almost half the price of the other.
If anyone can help answer these question, or even show my a DIY step motor set up that would cause the motor to rotate constantly, that would a HUGE help!
usually mixing applications need high speed(i guess).problem with steppers is at high speed you loose torque.so its better to go for DC geared motor.simple to control and gives good torque.
