The frequency of the applied voltage is constant.

Does the velocity of a car traveling at constant speed around a pole change?
yes, It accelerates (and does so at a constant rate - if the rate of turn is constant) in the direction of the turn. The speed is constant, but the direction the car is going changes at each instant in time because it is turning. And because it is changing direction, that means its velocity is changing (because velocity is speed plus a direction vector).Read more: What_happpens_to_a_car_moving_at_a_constant_speed_as_it_turns_a_corner
What calculated speed of a four-pole split-phase motor is 1800 RPM. However if you measure the shaft speed you will find it to be 1725 RPM. What causes this loss of rotational speed?
The loss of rotational speed is due to slip in the motor. Slip is a natural characteristic of induction motors and is necessary for torque production. The difference between the synchronous speed (1800 RPM) and actual shaft speed (1725 RPM) represents the slip in the motor.
What does the area around the North Pole experience constant?
The area around the North Pole experiences constant cold temperatures and darkness during the winter months, as well as continuous daylight during the summer months due to the tilt of the Earth's axis.
If four wave crests pass a pole each second what is the speed of the wave?
The speed of the wave is equal to the frequency multiplied by the wavelength. Given that four wave crests pass a pole each second, the frequency is 4 Hz. If the wavelength is known, you can calculate the speed using the formula speed = frequency x wavelength.
What kind of energy does a pole vaulter have?
A pole vaulter has kinetic energy as they run with speed, potential energy as they use the pole to propel themselves upwards, and gravitational potential energy as they reach the peak of their jump.
Why does a shaded-pole motor run at a constant seed?
The frequency of the applied voltage is consant.
Are the motor used in tape recorder are split phase?
AC motors are not suitable for tape recorders because the speed can not be kept sufficiently constant. Tape recorders use dc shunt-wound motors with electronic speed control.
How many poles can a shaded pole motor have?
2
What kind of motor uses a differential reluctance pole to produce starting torque?
shaded pole
What are the types of motor using in table fan?
The motor used in a table fan is usually a shaded pole motor.
A shaded pole motor coil will have a resistance of approximately?
15 to 40 ohms.
What will happen if you place too many washers on the end of a shaded-pole motor shaft?
The rotor will jam.
Why won't my shaded pole motor run?
A shaded pole AC motor has a part of it's stator short circuited by a copper ring. When the flux in the main part of the stator increases, the flux through the copper ring with have a small delay, since it wants to keep its flux constant. Therefor you get a small rotational component to the field distribution, which makes the rotor turn.
What are the applications of a shaded pole motor?
When the coil in the relay needs to run off an AC signal rather than DC. The shaded pole keeps the relay from "chattering" every time the AC current crosses 0v on the sine wave.
What if a shaded -pole motor is chattering or buzzing while it is turning the problem is most likely caused by?
A faulty or worn bearing.
What are some characteristics for a shaded pole motor?
The rotor is made up of laminated steel discs that are pressed on to a common shaft. This shaft has bearings mounted on either end which allows the rotor to spin within the frame of the motor. The shorting bars on the rotor are usually made of aluminium.
2 pole motor vs 4 pole motor?
A 2-pole motor has about 1.5 ft-lbs of torque per horsepower where a 4-pole motor has 3 ft-lbs of torque. also the speed of a 2-pole motor is twice that of a 4-pole motor. The speed of a motor is determined by: speed=(120 x freq)/no. of poles At 60 Hz, a 4-pole motor is about 1800 rpm where a 2-pole motor is 3600
