How many poles are within a DC motor?
It depends on the motor. They can be purchased with different numbers of poles. The number of poles mainly changes the speed of the motor.
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.
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
What pole motor is standard?
2, 4 or 6 poles
Why there is no starting torque for synchronous motor?
The 3 phase supply is provided in the stator of a synchronous motor which produces a rotating magnetic field.The stator has field poles(North and south). Now due to the rotating magnetic field the current is induced in the rotor of the motor as due to ampere's law, so the motor tends to move.Now as the stator poles induces opposite poles on the rotor, after moving the first pole pitch the rotor gets repelled by the opposite stator poles and due to the heavy inertia of the rotor it can't respond and the motor is standstill.Hence the synchronous motor is started with the help of an auxiliary motor or such called a pony motor to overcome this problem.
What is the relation between number of winding groups and the number of poles of electric motor?
same

What is the coil pitch of a motor with 54 slots?
which types connection of 4/6 poles 36 slots three phase motor advise no coils and groups (both rpm in single winding)
How do electromagnets work in a motor?
The poles of the electromagnet are repelled and attracted to the poles of the field magnet in the motor, causing it to spin a commutator or rotor in the motor. A brush flips the poles to keep the electromagnet spinning and the rotor moving.
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.
What Aboriginal groups had totem poles?
Not sure
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.
What is the relationship between motor POLE and RPM?
Relationship between motor rpm and no of poles
How speed of a squirrel cage induction motor can be varied?
There are two ways of changing the speed of AC motors,by altering the frequency or the number of poles in the motor. An increase in frequency of the supply voltage to the motor will cause it's speed to increase while reducing the frequency will causes the motor speed to drop. This is the method exploited by Variable Speed/Frequency Drive. The second method of changing the number of motor's stator poles is the difficult. The manufacture must design the motor such that the number of the motor's pole in operation can be increased or reduced. Increasing the number of poles increases the stator flux density which decreases the speed. Decreasing the number of poles does the opposite. This method is typically found in two speed motors and it's rarely used compared to VSDs.
