Slip, 
, is defined as the difference between synchronous speed and operating speed, at the same frequency, expressed in rpm or in percent or ratio of synchronous speed. Thus

Can you replace a three phase motor 3 Hp RPM 1420 with a single phase motor for a planer?
Probably not. The single phase three horse power motor will be much larger in physical size than its three phase counterpart, and will probably not fit.
What is the required thickness for 3 phase 3 HP AC motor?
The thickness of a motor is governed by the manufacturer that makes the motor. Some motors are built long and slender for example a submersible pump for a water well. Others are built with not much depth front to back but will have a diameter of six feet for example a synchronous motor for a large air compressor.
How much is skewing angle in three phase induction motor?
the skew angle varies from 0 degrees, depending on how much torque you want at near synchronous speed and how smoothly you want to transition with varying loads most motors all the shorting bars are parallel to shaft. skew is more often for lower current starting in motors that will turn on an off a lot
How do you wire a three phase motor if none of the wires are idetified?
If it is a three lead 3-phase motor, it is easy: connect the incoming three leads randomly to the three leads on the motor (one to one) so that there are a total of three splices. The motor will run but possibly in reverse If it runs in reverse, switch any two of the three splices ---- If the motor has more than three leads, and they are not marked, it is much more difficult. You will have to have a working knowledge of how to test the leads and compare the results with the information given on the nameplate
What are the advantages of three phase induction motors over the other motors?
A Single phase induction motor includes a main winding, an auxiliary winding, a run capacitor, & a subsidiary star device. The auxiliary winding is configured such that the number of turns of the aauxiliary winding through which a current flows, varies according to the operating mode of motor. When the motor starts, the number of turns of the auxiliary winding through which a current flows is reduced there by increasing the start efficiency of the motor. when the motor runs in normal mode, the number of turns of auxiliary winding through which a current flows is increasing there by increasing the operations efficiency of motor

How much is a three phase 20A motor in Australia?

Can you run a 570 volt motor on 480 volt three phase power supply?
No, the voltage difference is too much. A 570 volt motor falls in the 600 volt range which is separate from the 480 volt range of three phase systems.
What happens if you use synchronous motor in ceiling fans?
Synchronous motors are much more efficient at converting electric power into motion. However, the speed of the motor is controlled by the frequency of the electric supply. So a synchronous motor ceiling fan would be much more efficient, but the speed of the fan would not be controllable, unless frequency controlled power supplies (inverter power) are used.

How much is the amps to run a three phase motor?
To find the amperage of a three phase motor, the following equation needs to be used. Amps = HP x 746/1.73 x Volts x % efficiency x power factor. once all of the values are added you can find the amperage of any Horsepower motor at any three phase voltage. A standard motor's efficiency between 5 to 100 HP is .84 to .91. A standard motor's power factor between 10 to 100 HP is .86 to .92.
What supply is needed to run a 22kw 3ph motor?
question is incomplete, I think you ask how much current consumed by this motor. for starting this motor we need a star/delta starter and a three phase supply.

How much more efficient is a 2 hp 240 v 3 phase motor compared to a 120 v single phase 2 hp motor?
I would guess it would use a third less than a single phase motor. The voltage differences don't save but 3 phase does. A 3 phase motor also starts easier.
When you have 56KVA available in 3 phase supply how much is your available current in 3 phase and how much in 1 phase?
In three phase: I = (three phase VA) / (sqrt(3) x (phase to phase voltage)) for single phase: I = (single phase VA) / ((phase to neutral voltage)) keep in mine three phase VA = 3 x (single phase VA), and phase to phase voltage = 1.732 x (phase to neutral voltage) Therefore the single phase and three phase currents are the same (ie, the three phase currents are the same in all three phases, or balanced). But don't get available current and available power confused (KVA is not the same as KW).
