Knowledge of the basics together with powerful new test equipment vastly simplifies the job. Electric motors have had a reputation for being a mix of science and magic. So when a motor fails to operate it may not be obvious what the problem is. Knowing some basic methods and techniques along with having a few test instruments handy helps detect and diagnose problems with ease.

How to Wire an Auto Meter Amp Gauge | It Still Runs
You might have seen this in elementary school as the classic demonstration of a length of wire wrapped around a nail. A battery provides an electric current and the nail temporarily becomes a magnet. Theoretically, you could have a permanent magnet and an electromagnet that produce a similar magnetic field. Note: We used an old bolt from a pile of random hardware, but this might not have been the best material choice. In hindsight, we might have had stronger results with a better choice of steel. Then we tried turns to see how that compared.
AMMETER HOOKUP HELP!!!
When an electric motor fails to start, runs intermittently, runs hot, or continually trips its overcurrent device, there my be a variety of causes. Sometimes the trouble lies within the power supply, including branch circuit conductors or motor controller. Another possibility is that the driven load is jammed, binding or mismatched. If the motor itself has developed a fault, the fault may be a burnt wire or connection, a winding failure including insulation deterioration, or a deteriorating bearing.
Today we will construct a very simple bench power supply. Best of all this design does not require you to mess around with any high-voltage. One of the essential pieces of equipment for any electronics workbench is a power supply. A source of regulated DC voltage is something that every experimenter needs.
