Hi Friends,
I recently salvaged a motor from an old antenna rotor unit. It has two wires and I do not know what kind of a motor is this. It has no identification marks. I want to build a new rotor to drive a small antenna. So now I have few problems.
Is this a AC motor ? (when I gave a small DC it will not work. I dismentled it and found that it has a coil and a rotating permanent magnet. Power is being given to the coil winding. No slip rings and brushes)
It is not a stepper motor as it has no driver circuit.
What type of motors are there in usual antenna rotors?
If this a AC motor, can it be driven from a square wave puls generating circuit?
Would appreciete very much, if someone guide me to built a suitable circuit.
Thanks
Ravi
