I am in need of assistance regarding electric motors. Answered
I am planning on making a electric powered vertically sliding pet door. I have all the mechanical and pulleys etc worked out but am ignorant regarding small electric motors. I am very competent regarding wiring and circuits/relays etc, only issue is the power for the unit. I know they sell units like this but i want to build my own. I need the motor to move slowly one way and stop when i cut power using a switch and when next powered to reverse until the switch cuts power so on and so on. Any ideas as to where I can purchase a motor such as this? Radioshack has zilch, so i assume I am going to need to go online. Any help on this would be greatly appreciated. I have been planning this in my mind for quite a while, generally right around the time the dog door breaks in the dead of winter. Thanks for any help!
