IPM vs SPM Electric Motors

IPM vs SPM Electric Motors A PM motor can be separated into two main categories: surface permanent magnet motors (SPM) and interior permanent magnet motors (IPM) . Neither motor design type contains rotor bars. Both types generate magnetic flux by the permanent magnets affixed to or inside of the rotor. SPM motors have the magnets affixed to the exterior of the rotor surface. Because of this…

IT SPINS! Handmade electric motor! Entirely out of wire! They said it couldn't be done, but I have proven -- it merely shouldn't be done!

Photos don't really capture how ridiculously complicated this thing was to build, so I managed to film myself assembling the components too! Very proud of that.

In total, I've been working on this project on and off for roughly two years. This motor is my third version, though I went through something like seven designs of the commutator section (not counting how many failures it took to build a working example of a given design). I'm very proud of getting this to work at all.

Some close-up photos of all the components:

Six-way commutator. As the motor spins, this delivers electricity to only the correct pair of magnets at a time, leaving the other four off.

Magnet coils. I wound these by hand from very thin insulated wire. The center is a spiral of thicker insulated wire (darker orange) that protects the thin stands from the steel core and then wraps around the outside to hold everything in place.

Spring-loaded arms. These deliver electricity from the stationary frame into the rotating axle. They also have to hinge up out of the way or else there's no room to fit the rotor in place during assembly.

All the components laid out together before assembly.

And the full motor in all its glory!

A homopolar motor is built with a battery, a magnet and some conductive wire. The magnet provides a magnetic field that will interact with the magnetic field induced by the current in the wire.

A homopolar motor is a type of electric motor that uses a magnetic field to create motion. It is also known as a disc motor, a Faraday disk, or a disc dynamo.

The homopolar motor is made up of three main parts:

A battery: This provides the electrical current that flows through the wire.

A magnet: This creates the magnetic field that interacts with the current in the wire.

A conductive wire: This is the wire that carries the electrical current and interacts with the magnetic field.

The wire is typically shaped into a disc, and it is placed between the poles of the magnet. When the battery is connected to the wire, a current flows through the wire. This creates a magnetic field around the wire. The magnetic field of the wire interacts with the magnetic field of the magnet, and this causes the wire to rotate.

The speed of the homopolar motor depends on the strength of the magnetic field, the amount of current flowing through the wire, and the size and shape of the wire.

Homopolar motors are simple to construct and can be used to generate small amounts of electricity. They are often used in educational demonstrations and experiments.

Here is a diagram of a homopolar motor:

The battery is connected to the wire, which is shaped into a disc. The disc is placed between the poles of the magnet. When the battery is connected, a current flows through the wire, creating a magnetic field around the wire. The magnetic field of the wire interacts with the magnetic field of the magnet, and this causes the wire to rotate.

The simplest battery motors

[industrialmotor]

what do you think of linear induction motors

Better than linear synchronous motors as it doesn’t require complex start up logic

And induction is a cool as hell way to create motion! Like yeah imagine a transformer, but short 1 part and allow it to move???? And it moves!????

Baby Brains

The human body carries on developing after birth – but the rate of these changes is still in question for developmental biologists. Here scientists take magnetic resonance imaging (MRI) scans of sleeping children’s cerebellums over the first two years of life, showing months 1–5 (top row) and regular intervals afterwards (bottom) from three different angles. While the young brain is constantly growing, it’s growing at a faster rate (warmer colours) during the first six months. The researchers investigated further, analysing the scans from 235 healthy children and looking at how 27 individual regions of their cerebellums change – finding, for example, that changes in specific ‘lobules’ corresponded with milestones in fine motor skills. This data could be used to pinpoint developmental windows for further study, or even to diagnose health issues or injuries during a toddler’s early life.
