Hello All - Can anyone confirm if there is a standard for which reversable DC motors are wound and what the expected rotation is? I have a few motors that when bench tested opperate with an opposite rotation than the others, all motors from the same manufacturer.
When applying Battery (+) to F2 while connecting A to F1, what should the rotation be, as veiwed from the drive end of the armature ?
Hi Robert, welcome to the forum.
If you are not familiar with DC motors, a simple test will tell you that any DC motor is bidirectional. You just have to connect the terminals of a power source i.e a battery to the terminals and see it for yourself. As for the designations you described, they're not more than just a guide for you to identify the pins.
I'm attempting to determine if there exsists a design guideline that all motors are to spin X direction when Y connections are made. Any thoughts, or is there no continuity (pun intented) in DC motor circuitry from one manufacturer to another ?
If you look on the product webpages of DC motor manufacturers they usually have CW or CCW parts listed in each motor, so they can supply as CW or CCW depending on the customer order.
Most small brushed DC motors with permanent magnet stator are reversable (by swapping the wires) with no problem.

there is a very minimal "circuit" equivalent to a DC motor.... but not qualified to be called a circuit by itself, IMO. There are always separate components used to render the motor bidirectional. You might want to look up on push-pull drivers, or we call them H-bridges.
