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.
Speed (RPM) = 120 x f / p f = frequency p = number of poles. 2 poles, speed = 3600 RPM 4 poles, speed = 1800 RPM
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
The number of poles in a motor will determine the speed of that motor. n=speed, f=frequency, p=# of poles. n=(120f)/p So a 6 pole motor is rated to operate at n=(120*60)/6=1200 rpm. assuming 60Hz frequency Or a 8 pole motor is rated to operate at 900 rpm. Of course due to slip the rotor will always spin slightly slower.

Relationship between motor rpm and no of poles
Speed (RPM) = 120 x f / p f = frequency p = number of poles. 2 poles, speed = 3600 RPM 4 poles, speed = 1800 RPM
It is based on the RPM of the motor. Use the following formulas for 50 and 60 Hertz.

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.

It depends on the frequency. At 60 Hertz, with an ordinary two pole synchronous motor, you cannot have an RPM that is greater than 1800, so a six thousand RPM motor has to have a different power supply.
The number of poles in a motor will determine the speed of that motor. n=speed, f=frequency, p=# of poles. n=(120f)/p So a 6 pole motor is rated to operate at n=(120*60)/6=1200 rpm. assuming 60Hz frequency Or a 8 pole motor is rated to operate at 900 rpm. Of course due to slip the rotor will always spin slightly slower.
Yes, IF the motor is a dual-voltage motor to begin with. There should be re-connection instructions on the motor nameplate, or available from the manufacturer. The motor will list both voltages on the nameplate. If it only lists one, then the motor cannot be re-wired to a different voltage.
You would use a worm drive meshed with a gear that has 130 teeth.
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.
