2 functions.
1 to cool the motor
2 to blow debris away from the motor.
Motors in heaters are to run the fans to distribute the heat over a larger area.
For AC motor, you can change motor RPM by changing its supply voltage or by changing supply frequency. For DC motor, you can change motor speed by controlling armatyre voltage or field current.
Most electric motor brushes fail because, in normal use over a long time period, the brush material simply wears away.Other answersThe material from which the brushes are made is porous and some of the pores are very fine that the material has an exceptional ability to absorb other substances into its structure. Moisture being one, it plays an important part in the functioning of a brush contact by affording a substantial degree of lubrication. The moisture is trapped under the inevitable irregularities of the contact faces of the brushes and forms an outside film on the commutator and it is with this film that the brushes make contact.Other failures could be due to metal fatigue.
160 Amp. MCCB 45 KW Contactor (67.5-112.5) Thermal Over Load
It is a ferrite core over coax cable, AC or audio cord. It prevents electro-magnetic interference (EMI) and cuts down on radio-frequency interference (RFI).Prevents electric magnetic interference (EMI) and cut down on radio frequency interference (RFI)Simply snap it over any coax cable, AC or audio cordRoSH compliant
an electric motor can be build with over 2000 rpm,by increasing the supply frequency.
The output energy of an electric drill is typically measured in watt-hours (Wh) or joules (J), which indicates the amount of work it can perform over time. This value can vary depending on the power rating of the drill and how long it is used.
It's a regional term like "pop" is to "coke". In the south I have actually heard people ask if you want a "orange coke" or a "coke coke". "Pop" is never used... In the north I have heard the term "drill motor" used where other areas will just refer to it as a "cordless" drill, or "drill".ANS 2 I believe it's more a technician/layman thing. -All over the world amateurs say "drill" meaning the whole machine AND bit . We technicians or carpenters see the two 'pieces' -the portable drill motor, and it's variety of 'bits'.In short, to the asker, I would say a 'drill' is actually a drill bit, and a 'drill motor' is the part that powers it.
the turbo has nothing to do with blowing the motor it's the amount of boost you run the will blow it the bigger the turbo the longer it will take spool.
A small electric motor used to turn an internal combustion over to get the larger engine running.

there is a rev limiter in the computer to keep you from blowing your motor.
a properly designed motor wont overheat unless it is overloaded this is something like 3/4" drill with a 1/4" shaft that is used to drill in steel sometimes hole saws have a 1/4" mandrel that will hold the entire line of saws the motor must be matched to the load
There are many different ways. On an outboard motor it can be a rope, pulley or an electric motor. Inboard engines are usually bigger and have electric, pnuematic or hydraulic starters. They can also be turned over with a hand crank if not too large.
An electric car is powered by a large electric motor. This motor is powered by the use of magnets in a coil inside the motor. When electric current is run through the motor, the drive shaft spins. This type of motor has an advantage over internal combustion engines because it offers all its torque at 0 rpm, thousands less than internal combustion engines. This makes the car quicker to start and accelerate.
Electric fan motors have a common problem of the bearings binding up and stopping the armature from turning. This might be caused by accumulated dirt, or even the bronze bushings (the bearings) actually shrinking. They can shrink over time because their retainers push in on them constantly. If you can not get a replacement motor (or don't want to spend the money), you can try what I have done in the past. You can take apart the motor and drill out the bushings with a drill bit. Also polish the armature shaft where it rides in the bushings. But, if you drill out the bushings too big the motor will rattle. Oil the bushings when you are done. If this sounds like too much work, you can try just spraying the bearing surfaces with a penetrating oil.
The main way that people are retaining ownership over an electric vehicle is by changing their existing car into an electric car. Do you really think that people are racing out to purchase the latest hybrid? The truth is people have found a smarter way to save money on gasoline. The best motor a person can buy for making this change is the DC series motor. This motor can only be used on flat land.
