In this video we will be having a closer look at an old induction motor or asynchronous motor that I got lying around. In order to see whether it still works, I will show you exactly how to power such a motor and how it creates its rotational movement. Along the way you will also learn why such motor types are still the most widely used ones in the world and I will also partly compare them to DC, BLDC and stepper motors. Let's get started!

One big advantage with these motors is the fact that you can use a frequency converter, and thus adjust the speed of the motor without losing too much torque. There is a lot of good frequency converters out there that are not all that expencive. There is a lot of cool stuff you can do with the frequency converters. I have used this sort of setup quite a few times in packing robots, ship systems etc. The motors are cheap and reliable and you can use a 3x220 motor with frequency generator that uses 1x230 supply. Very handy sometimes As always great video !

Hi Scott, many thanks for the very informative description of how asynchronous motors work, the way you describe the workings, even an old bloke (78) can understand, I have been dabbling with electronics for most of my life and never really understood how such motors worked. Many thanks young man, regards from Ray in North Wales

@spazionauti2008 3 года назад

Just a little safety tip. When there's need to test a motor that isn't connected to anything, always put some tape around the mechanical tab. Because due to the centrifugal force it could fly away and hit something or someone. Usually when you open an asynchronous from the box, it should have a plastic protection for the tab.

Great work. You did a great job explaining this. We use a lot of 3 phase 480 Volt motors where I work as well as several 4160 volt motors. The stator is large enough to stand inside on the 4160 volt compressor motors we have. It’s a lot of fun to work on them.

@aps7637 3 года назад

@b4uc2far95 3 года назад

maxhouseman The United States. The most common motor voltages here are 120/240/480 but in some industrial settings we use 4160 volts. We typically use a VFD to start motors this big in order to ramp them up, then we switch them over to line voltage once the VFD and line voltage are synchronized.

@b4uc2far95 3 года назад

maxhouseman that’s really cool. I’m an electrician and instrumentation technician here in the states. We bring roughly 15 KVA in to our facility’s switch gear then distribute 4160 and 480 volts out of them. We use transformers to get our lower 120/208 voltage for things like lights and basic power panels. We also use a lot of 24 VDC instrumentation (flow meters, temperature transmitters, level transmitters, and control valves). There’s never a dull moment with this much stuff.

@b4uc2far95 3 года назад

BTW our facility manufacturers ammonia nitrate so as if the multitude of different equipment doesn’t make it exciting enough, we’re producing hundreds of tons of Ammonia Nitrate solution too. It’s a very cool process but can definitely be super dangerous.

I was just having "the talk" with my son - about motors of course. AC Induction motors are the power workhorse of the house - pumps, fans, compressor (AC and refrigerator), Washing Machine, Dryer - because they are cheap power; but, only when you can use them for single speed on/off power. The electronics required to control their speed usually costs more than the motor. For small motors, ones that run on batteries, an/or ones you need to change the speed of, brushed DC motors are still the king. The new kid on the block in the house are brushless DC and AC synchronous motors (which are actually the same thing) as the the electronics to drive these are getting cheaper all the time and with all the advances in Rare Earth Magnets, these motors can pack a LOT of power in a very small space.

@johnmiller8884 3 года назад

"only when you can use them for single speed on/off power." And not even a constant speed. your application need to account for the fact that slip varies by load.

@connecticutaggie 3 года назад

@@johnmiller8884 I agree, the speed of induction motors is load dependent; but, that is even more the case for DC motors. The only easy constant speed motor is a synchronous AC and that is rarely/never use in US homes due the the lack of three phase power. That is changing now some as the cost of electronic motor control has really dropped (Ex: drones) and they are finding their way into places like cordless drills, etc. The one challenge to overcome is that Induction motors are just so cheap - less that 1/4 the price for the same power and the only control components they need is a capacitor and maybe a time/centrifugal switch.

Most machines at my work use these motors so very familiar with them. Very reliable and also very quiet operation. In a not so quiet environment though as what we do: grinding and sawing metal is by itself a very loud buisness. Everything we do is not deafening loud though so that most of our machines by themelf like the drill press are not very loud is a good thing and also . these things last forever. The drill press is from around the 60s i think and stll runs as new. Thats reliability!
