Q:What's the difference between DC motor carbon brush and AC motor carbon brush?
The role of the motor is to change the current direction of the DC motor and AC motor, the DC motor is to change the rotor's conductive coil, thereby changing the rotor magnetic pole. Thereby changing the motion of the motor. The carbon brush is used for motor commutator or slip ring, as sliding contact body import and export current, its thermal conductivity, and good lubrication performance, and has certain mechanical strength and direction of the spark of instinct. Almost all motors use carbon brush, which is an important component of the motor.
Q:Question on AC/DC motors?
We tried this with an old AC washing machine motor at a Girl Scout meeting. It would make voltage - less than 1 volt on the volt meter as I recall. No way it would light a 60 Watt bulb.
Q:How do I demonstrate an item running on AC that is intended to be DC powered?
Q:what is the exact operating principle for induction motor ?
Q:I want to attach 2 series motors to 40V AC how much current do I need if each motor is 24V DC?
It won't work. You can't connect a DC motor to an AC supply. It will just sit there and eventually burn out.
Q:where can i find an ac electric motor at least 65hp for an electric car prototype?
first how big a car are you going to build or are you going to try to set a land speed record. two where are you going to find a electric cord long enough to run the car. electric cars are DC NOT AC. the smaller the car the smaller the HP needed you could run a old VW bug on a 15 hp dc motor. the smaller the car the smaller the motor the smaller the battries needed. think small. with DC motors the more power in the higher the HP till something smokes.
Q:How do I change the speed of the motor?
There are several schemes. The 1. is to change the ratio of the mechanical driving wheel and driven wheel driven by the motor. The 2. is to use mechanical transmission to change the speed of the motor. 3. is to use electronic governor to change the speed of the motor. As for which scheme to use, it depends on your environment.
Q:I've seen on facebook page of some technical institute that Tesla was NOT the first to build the AC motor, do you know who was first then?
3 PHASE synchronous motor was made first by Friedrich August Haselwander in 1887. 3 PHASE cage induction motor was built first by Michael Dolivo-Dobrowolsky in 1889
Q:How resistance is produced in an electric motor? and if its not produced then why don't shock circuit occurs?
Hi, The electrical circuit that possesses resistance are the windings of a motor.A motor has two types of windings viz. Field windings and Armature windings. See,when we talk of only resistance then it is logical to understand the theory of a dc motor only(NOT ac motor) in regards to your question. In general,the resistance of field windings is maintained HIGH by using a coil of larger number of turns made by thin copper wires as the resistance is inversely proportional to the area of cross section of the wire. This is because,the initial applied voltage to the field windings is very high and may cause to generate a large current in field circuit in case of low resistive windings.(Remember Ohm's law). This initial transient current is very damaging and so undesirable for use in the field circuit. On the other hand,the resistance of armature windings is kept LOW by using small number of turns made of copper wires of larger area of cross section. This is because the armature circuit is rotary member of the motor and has capability of self limiting the resistance in the form of BACK EMF. Even the initial value of current is very much high in armature circuit too but the use of STARTERS limit the current by grading the value of effective resistance.Once the rotor attains sufficient rpm,the generation of BACK EMF now,limits the current in the circuit and starters are removed. So,this is a misconception that motor circuits do not have resistances. HOPE IT WORKED!!!
Q:In the main circuit of AC motor, fuse can be used as short circuit protection, can it play the role of overload protection at the same time, why?
Short circuit protection: some devices can monitor abnormal conditions in the work circuit (such as short circuits). When abnormal happens, the circuit is cut off and alarm is sent to prevent further expansion of the damageA typical short circuit protection is a fuse. When the short circuit is short, the current is very high. When the fuse is blown, the circuit will be out of power.Overload protection: to prevent the main power line from overload protection caused by overheating damage and installation of overload protection equipment
