How much rpm for 12 volt ac motor?

The formula for RPM is, RPM = Hz x 60 x 2/# of poles the motor has. To answer this question more information needs to be stated.


What is the price of a 2500 rpm generators?

The standard rotation of a generator engine is 1800 revolutions per minute. This standard speed is brought about by the number of poles that the generator portion of a generator has in its stator.


How much minimum RPM is required by a turbine to generate Electricity?

As most turbine generators are large enough to be connected to a grid, they will operate at a speed that is predetermined by the grid frequency and the generator's electrical configuration (mainly the number of 'poles' the generator has.) A generator will always run at some multiple of the grid frequency. Most steam turbines on 60 Hz systems operate at either 1800 or 3600 RPM. Hydroelectric turbines run much slower and have a large number of poles. The turbines at Parker Dam, CA, for example, run at a speed of 94.7 RPM. A generator may run at a faster or slower speed if it is disconnected from the grid, but once synchronized it runs at a constant speed. Under certain circumstances a generator may experience a 'slipped pole' (where, for instance, more input force than designed forces it to jump ahead a fraction of a turn), which creates a great deal of physical stress and is something that is considered undesirable operation.


What is the speed in RPM of a ceiling fan?

945 rpm


How many mph is 1530 rpm?

If you're trying to determine the speed of your car by looking at the RPM, you can't do that without knowing the gear ratio that exists between the engine and the wheels. What you can do is to drive in different gears and see what the speed is for various engine RPMs.

What is the maximum RPM does a 3 phase motor run at?

The formula for RPM is ; RPM = Hz x (120 (constant)) divided by the # of poles. Number of poles a motor has; # of poles = Hz x (120 (constant)) / RPM.


How is The RPM of an electric motor is determined?

The two main factors are the frequency and the number of poles of the motor. A formula for RPM is HZ x 60 x 2/ number of poles the motor has.


Why single phase series motors have large number of poles?

All motors have a set number of poles for the speed they are designed to run at. 3600 rpm are 2 pole,1800 rpm are 4 pole, 1200 rpm are 6 pole, ect.


How do you check number of poles on a three phase induction motor?

Name plate data should indicate the number of poles / RPM. For speed N= (120 x Frequency) / Number of poles Using this formula you can find out the number of poles, provided you have other parameters available. If no data is available, run the motor on no load, and measure the rpm, know the frequency, calculate the poles.


What is relation between feed and rpm?

Feed Rate = No of Cutting teeth x RPM x Feed per tooth.


Relate the frequency of the generated voltage to the speed of the machine and the number of poles?

N=120f/P where N - number of rotations in rpm f - frequency in Hz and P - number of poles


The speed of a synchronous motor with 60 Hz power supply is?

Speed (RPM) = 120 x f / p f = frequency p = number of poles. 2 poles, speed = 3600 RPM 4 poles, speed = 1800 RPM


Relation between voltage and RPM?

voltage depend on current and resistance r.p.m depend on no of pole


How do you tell how many poles a 3 phase 480 volt motor has?

It is based on the RPM of the motor. Use the following formulas for 50 and 60 Hertz. The mathematical formula is Frequency in Hertz times 60 (for seconds in a minute) times two (for the positive and negative pulses in the cycle) divided by the number of poles. For 60 hertz, the formula would be, 60 x 60 x 2 = 7,200 no load RPM divided by the number of poles will give you the nameplate RPM of the motor. eg from above formula 7200/2 pole = 3600 RPM, 7200/4 = 1800 RPM, 7200/6 = 1200 RPM


What is relation between speed of generator and its voltage and torque on generator shaft and current produced by generator?

power = torque * rpm


Why the same RPM is required to parrellel two generators if voltage and phase are the same?

Assuming the number of poles is the same, you need the same RPM to maintain phase. Otherwise, voltage and phase are not really the same.
