A permanent magnet motor is an engine where the magnets are glued or riveted to the outside of the rotor. The stator is the stationary part of the engine. The field coils are wrapped around the stator, and the armature is the rotating part of the engine. Permanent magnet motors are not brushless. The armature contains the brushes that make contact with the commutator. The commutator is what reverses the current direction in the armature coils as they rotate. This reversal of current direction creates the rotating magnetic field that makes the armature rotate.
There are many types of electric motors, but one of the most common is the permanent magnet (PM) motor. PM motors are used in a wide variety of applications, from small toys to large industrial machines. PM motors are often more efficient than other types of electric motors because they don't have any moving parts. This means that there is less energy lost in the form of heat and friction. Additionally, PM motors are often smaller and lighter than other types of motors, which also makes them more efficient. Despite these advantages, PM motors are not always the most efficient option
Yes, permanent magnet motors are self starting. The magnets in the motor create a magnetic field that interacts with the armature to create torque. This torque is what starts the motor.
Tesla motors are not permanent magnet. The company uses induction motors in their vehicles.

Installation went smoothly. Good results. I did some shopping. By far, this was the finest offer. The one drawback is that the box isn't weatherproofed for outside use, so I had to buy and install an indoor weatherproof enclosure from Home Depot. Drilling holes was necessary to connect the electrical conduits and cables, which cost an additional $25.

I have a broken life-size dancing Santa (for Halloween he is a zombie in a hazmat suit.)I swapped out the motor for a too-small one from a model railway. It was soon obvious that it was too feeble.My zombie is now dancing all night thanks to the new motor.

One of these motors is operating flawlessly in the soldering fume extractor I created and designed specifically for myself. An antique fume extractor prototype, shown in the accompanying photo, has a motor spinning a red impeller.I'm using a 12v battery Power bank to power the engine and an LED lighting strip. The motor has been put through several prototypes over the past month with no problems, even though I've only been using the fume extractor for a few days. I have two of these motors, so as long as the one I'm using holds up well, I'll just swap it out for the second motor.

The wire length was ideal for my high school students' toothbrush head-style bristlebots. Red and blue are challenging to remove when necessary from cables, but we found a solution. I'm not sure if design has a true fix for it. These motors are consumable in the sense that at least half of the 20 we purchased pittered out by the time we were finished with our unit, contrary to my expectations that they might last a year or so (about a month). However, we still learned a lot from them.

Using a PWM controller and a 20 amp power supply, I attached a 16 inch by 1/8 inch plexi disc to this motor using a flange. With thus much mass, the acceleration must be gradual to prevent the motor from becoming irate. 12230 RPM were achieved at 12.6 volts. I had to use a table saw to cut the plex, then rough sand it to make it round. After mounting the motor, I finished sanding the edge to align it with the motor axis. With so much bulk, it required all 20 amps of my power supply to accelerate to full speed, and the spark at the brushes appeared to be good. The motor warmed up but did not get extremely hot, and I had no trouble aligning the disks. In order to operate two disks for a Wimhearst generator, I ordered another with a bracket, a 60 amp PWM controller, and breaking out two of my 13.5v x 40 amp power supply in parallel.

used a wind turbine generator with a 3000 RPM version. 310RPM/V is the motor constant when there is no load. The constant is 533RPM/V, with the ideal load being around 3.7 Ohm. Over 2500 RPM, efficiency is roughly 60%.
No, magnets cannot create infinite energy. While they can create a magnetic field, this field requires energy to maintain it.
Yes, magnets can power a motor. Magnets can create a magnetic field that can interact with the magnetic field of an electric motor to create motion. This interaction can be used to power a motor.
Yes, permanent magnets can be used in motors. In fact, many motors use permanent magnets in their construction. Permanent magnets are often used in electric motors because they can create a strong magnetic field. This magnetic field can interact with the electric field of the motor to create rotational force.
Permanent magnets are made from certain alloys of rare earth metals. The strength of a permanent magnet can be measured using the coercivity of the alloy. Coercivity is the property that gives a material the ability to resist being demagnetized. It is the measure of how hard it is to reduce the magnetization of a material. The coercivity of a permanent magnet is very high compared to other materials. The coercivity of a permanent magnet is what gives it its permanent magnetism. Permanent magnets can lose their magnetism if they are heated above a certain temperature
A permanent magnet motor is a motor that uses magnets to create torque. This type of motor is typically used in electric vehicles and hybrid vehicles because it is more efficient than an internal combustion engine.
Permanent magnet motors are becoming increasingly popular due to their high efficiency and reliability. But how long do they actually last? The answer largely depends on the quality of the magnets and the operating conditions. Generally speaking, high-quality magnets in well-designed motors can last decades. However, it's important to note that even the best magnets will eventually lose their magnetism. This process can be accelerated by high temperatures, mechanical stress, or exposure to electromagnetic fields. So, while permanent magnet motors can last a long time, there is no guarantee that they will last
