- Q:what should i do to make it really fast?use more magnets? how do i reduce friction?how many coils?thanks!!!!
- Welcome to the the World of Electric Motors. How to Builda 2 Amp Motor, a step at a time. Coiling, position of Magnet (Type of Magnets), choice of Bushing and bearings, all play a integral part of making either a High torque or in this case RPM motor. Assuming that you are operating a DC Motor, (AC Motor, don't usually use magnets, but there are some out there) Start with Basic Design Link 1. - Answer you question about number of magnet (More accurately the Magnet strength) - And the Number of Coils Request for Speed Link 2. Summary For Speed, usually requires a lot of coils, generating a rapidly changing field, expect a few armature and alot of sections of magnets. Note 2 Ampere is al lot of current, and can easily harm any careless person. Check several time, visually and with the proper equipment before energizing the equipment. Friction reduction is a complete science by itself. If it is a School project, consider Dry type of Lub such as Graphite Carbon. As the running duration is short. (tens of minutes runs, with long period of down time that allow inspection) If it need a longer running time is expect, consider commercial grade stuff, such as Air bearings.
- Q:also when working in generator mode, what type of current is generated ac or dc???
- you usually plug in a d.c. motor you usually generate a.c., then convert to d.c. Don't forget to vote for best answer!
- Q:I have two types of machines which have a water jet drive, together with a motor. one has an inverter driven DC motor the other an inverter driven AC motor. If the water jet makes the load run faster than the set speed of the motor, can/does the different type of motor allow itself to be quot;pulledquot; round faster? or is a braking force applied to the motor. I am mostly interested the difference, if any between AC and DC motor in this respect,or will both do the same job depending on how the inverter is set up.
- Both an AC motor and a DC motor can apply braking force if the load exerts torque tending to increase the motor speed. When applying braking torque, either type of motor will function as a generator and transfer power from the load to the power source. A load that applies torque in the direction that would increase the motor speed is often called an “overhauling load.” An AC motor control inverter, more often called a variable-frequency drive (VFD), is normally not designed to accept energy returned from the motor. A standard VFD can be expected have some means of protection that might allow a limited speed increase and de-energize the motor if the limit is exceeded. If the motor id de-energized, it will be driven to a higher speed by the load, but most AC motors can tolerate being driven considerably above the normal speed. VFDs can be purchased with a dynamic braking circuit that will dissipate braking energy in resistors or a regenerative circuit that will return braking energy to the AC power source. Sometimes a small amount of dynamic braking control capacity is included in a standard VFD, but resistors usually need to be added externally. A DC motor controller is usually a converter or chopper. The controller for a permanent magnet DC motor might be called an inverter, and the function would be the same as a VFD controlled permanent magnet synchronous motor. DC motor controllers can be furnished with either dynamic braking or regenerative braking. DC motors are generally less tolerant of over-speed operation.
- Q:Seven month old 230V, 7.5hp, 1 phase motor with start/run capacitors having trouble starting natural gas well compressor. I am pretty sure the load is still the same. Once started the motor runs within specs. Could it be the start capacitor?
- Induction motors are about as simple as they get. Pretty much just a couple of coils of wire. If it runs okay and has trouble starting, it pretty much has to be the cap. That being said, some have a switch contact inside that closes when stopped to place the cap in circuit and opens when revs pick up taking the cap out of the circuit. Usually it will be a spring loaded contactor. If you have one, just inspect and clean as needed.
- Q:A 3 phase, 2 hp, 480 volt AC motor online? (case/price doesn't matter)
- pls visit www.electricity.uk for for knowing all bout engineering
- Q:Replacing fan motor on AC condenser?
- There is no fan motor on the condensor. The fan is on the radiator. The other fan that also operates the heater is on the evaporator end.
- Q:Is it an universal motor which works on ac or dc voltage,how does it work,speed regulation rheostat foot pedal,I mean can someone explain me technically how a sewing machine motor works,and how to connect it back after rewinding,thank you.
- Yes it is. The type of motors sewing machines use are electrically noisy.
- Q:The purpose is to show a small scale (for the classroom) example of what would happen if something like a small battery operated fan were running on AC instead of DC. I would like to show the fan going in one direction, then change direction, as the current changes direction. Is this even possible? From my limited understanding, most items that use an AC source, but need DC power, have rectifiers to keep the current flow going in the same direction. I want to demonstrate what would happen if there was no rectifier.Thanks.
- A okorder /
- Q:An electric water heater draws 20 A rms at 240 V rms and is purely resistive. A large AC motor has the same current and voltage, but inductance causes the voltage to lead the current by 20 degrees.
- The water heater power is 240*20 = 4800 W The Motor Power is V*I*cosθ = 4800*cos20? = 4510 W
- Q:There is no magnets in an induction motor so is this even possible.
- The answer is that you need a field. Just how that field is generated varies. In some cases, remanence is used to initiate the magnetizing current. In others, external sources are used.
