Mell What is the difference between 2 pole and 4 pole motor?
A 2 pole motor has high speed due to less number of poles. Conversely, a 4 pole motor has low speed due to more number of poles. A 2 pole motor is more efficient on the flip side, a 4 poles motor is less efficient. A 2 pole motor has more RPM value; on the other side, the 4 poles motor has fewer revolutions per minute.
What is meant by 4 pole motor?
4 pole motor is a type of motor with 4 magnetic poles or two pairs of magnetic poles, with a north-south-north-south configuration. A 4 pole motor consumes more energy, has fewer revolutions per minute, and delivers more torque per horsepower and work output. This type of motor is suitable for heavy power applications.
What is the difference between a 4 pole and a 6-pole motor?
Using this equation, a 4-pole motor at 60Hz has a speed of 1,800 rpm, while a 6-pole motor at 50Hz has a speed of 1,000 rpm. However, this is actually the speed of the magnetic field, called the synchronous speed, which is not always equal to the shaft speed.
What is the rpm of a 4 pole motor?
| Approximate Electrical Motor Speed (rpm) | ||
|---|---|---|
| No. Poles | Speed with Rated Load | Synchronous Speed (no Load) |
| 4 | 1725 | 1500 |
| 6 | 1140 | 1000 |
| 8 | 850 | 750 |
Can a 2 pole motor be 3 phase?
On a three-phase motor the pole pattern has to be repeated for each phase. Therefore a 2=pole, 3-phase motor will have six poles.
What is the RPM of a 6 pole motor?
1200 RPM
Six-pole motors run at 1200 RPM unloaded and between 1050 and 1175 RPM loaded.
What is differene between 2 pole 4 pole electric motor?
2 pole motors have twice the speed of a 4 pole motor. Rotor of the 2 pole motor complete one cycle for every cycle of the source, while the rotor of the 4 pole motor completes only half a cycle for every single cycle of the source. Therefore, 4 pole motors consumes twice the energy of the 2 pole motors.
How many Poles are in a motor?
A motor that contain two poles (or a single pair of magnetic poles north and south) are said to be a 2-pole motor. Often stator windings are the north and south poles. Number of stator windings can give any reasonable number of poles ranging from 2 to 12.
What is 4 pole?
4-Pole Motor. A motor that contains four poles in the stator (or two pairs of magnetic poles) in alternating order; N > S > N > S. The synchronous speed of a four pole motor connected to the mains power is 1500 RPM, which is half the speed of the 2-pole motor.
What is an RPM motor?
RPM (Revolutions per minute) RPM is one of the most important specifications of a DC motor. RPM, which stands for revolutions per minute, is the amount of times the shaft of a DC motor completes a full spin cycle per minute.
