Motor analyzer
Motor analyzer
(OP)
I'm thinking of buying a All-Test Pro 31 instead of a quality megger.
Does anyone have any first-hand experience with one.
Here's a link with some info;

RE: Motor analyzer
The unit you linked to looks like it performs some farly simple straightforward tests, based on pulsed or A/C measured winding impedences. There are other testers available also. In my own experience, for users of motors (as opposed to motor repair facilities), when a motor doesn't function properly it can be found with a multimeter and megger. The item you describe seems to be a handy device, but not for finding problems with the motor circuit itself, except very indirectly by learning a bit about failures of motors connected to any particular power circuit when (or should I say "as") they fail.
It looks most useful for determining the condition of "used" motors, or as a final quality assurance check of motors that have been rebuilt/ repaired/ rewound.
Be certain that any such unit you buy is well built and warranteed by a reputable manufacturer. If it breaks, becomes unstable, gives questionable readings etc. you need to be able to verify its correct operation.
remember: An opinion is only as good as the one who gives it!
