What is a consequent pole motor?
A Consequent Pole Winding is a three-phase AC induction motor winding that is concentric wound (coil inside of a coil), but it only utilizes half the coil groups of a Concentric Winding.
What is a consequent pole rotor?
The consequent-pole-type rotor has buried permanent magnets (PMs) polarized in the same radi… Metadata. Abstract: We describe the basic characteristics of a consequent-pole bearingless motor. The consequent-pole-type rotor has buried permanent magnets (PMs) polarized in the same radial direction.
How many speeds does a consequent pole motor have?
Consequent pole motors have a single winding for two speeds. Extra taps can be brought from the winding to permit reconnection for a different number of stator poles. The speed range is limited to a 1:2 ratio, such as 600-1200 rpm or 900-1800 rpm. Two-speed, consequent pole motors have one reconnectable winding.
How does the consequent pole motor change speed?
Since the number of poles has been doubled, the magnetic field will travel only half as far during one complete cycle. Consequent pole motors have an advantage over some others types of variable speed alternating current motors in that they maintain a high torque when speed is reduced.
What is the advantage of consequent pole motors over some other types of variable speed motors?
What is the advantage of consequent pole motors over some other types of variable speed motors? They maintain a high torque when speed is reduced. A consequent pole motor has synchronous speeds of 1800, 1200, and 900 RPM.
Which is better 2 pole or 4 pole?
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.
Which is better 2 pole or 4 pole motor?
How many Poles are in each phase?
As you will note, there are a total of six poles or two poles per phase. The Phase 1 poles are located at 360 and 180 degrees while the Phase 2 poles are at 300 and 120 degrees. The Phase 3 poles are located at 60 and 240 degrees.
What is the difference between phase and pole?
Summary. An electric “pole” describes an electric charge determined by the number of protons and electrons in a given atom. An electric “phase” describes the rate at which the voltage in an alternating current oscillates.
How many poles does a 3-phase motor have?
The most basic 3-phase brushless motor is a 2-pole 3-slot motor. There are various combinations such as 4-pole 3-slot, 4-pole 6-slot, and 16-pole 12-slot. When the number of poles and the number of slots increases, a large torque can be obtained and the torque pulsation also decreases.
Are 3 pole and 3-phase the same?
The difference is found in the amount of conductors that are connected, or bridged, by the three-pole conductor. Used most often in a three-phase electrical system, a three-pole breaker connects three different conductors, such as is often required by heavy duty industrial motors.
