How to explain the double single winding of the motor?

1. A single winding is a coil that makes up each pole.

2. Double winding is two identical (or concentric) windings to form an electrode, and some are called single sets of bags and double sets of bags. Like a washing machine motor, if the starting winding is double winding, it is eight coils to form four poles, and a single winding is four coils to form four poles.

Motor double and single winding is a form of organization of motor winding, the main difference is the number of coils and connection method of the winding.

Single-winding motors have only one set of coils, while double-winding motors have two sets of coils.

Dual-winding motors typically have higher efficiency and higher reliability. Dual-winding motors work on the principle that when a set of coils is energized, this set of coils creates a magnetic field that interacts with another set of unenergized coils to make the motor turn.

In a double-winding motor, the two sets of coils are often referred to as "primary coils" and "secondary coils" respectively.

Primary coils typically have a smaller number of turns and a larger wire diameter, while secondary coils have a larger number of turns and a smaller wire diameter.

The primary coil has fewer turns and therefore produces a weaker magnetic field, but a larger current that can provide a larger starting torque.

The secondary coil has more turns and produces a stronger magnetic field, but the current is smaller, which can provide higher speed and less torque.

In addition, the double-winding motor can also control the speed and torque of the motor by controlling the current of the two sets of coils.

For example, when the current of the primary coil is increased, the magnetic field increases, the torque increases, and the speed of the motor decreases.

Conversely, when the current of the secondary coil is increased, the magnetic field weakens, the torque decreases, and the speed of the motor increases.

You're talking about single-phase motors.

1.A two-speed motor is a group of windings in which the two-speed motor changes the logarithm of the poles by changing the way of connection to obtain different speeds. 2.

The working principle of the two-speed motor is roughly divided into two kinds, one is the multi-winding type, that is, two sets of coils, and different coils are used at different speeds. The second is to use the original coil to change the connection mode, that is, to change the current input direction, from a common pole to two display electrodes. The number of windings is different, the speed is 2 phase 2 880 4 phase 1440 rpm, the two-speed motor places the winding connection point outside the motor, the contactor controls the wire break, changes whether the motor winding is connected in series or parallel, so that the number of motor windings becomes two speeds of a motor.

3.The working principle of a double-winding motor is to change the number of pole pairs of the stator to change the motor speed, which is inversely proportional to the number of pole pairs. When the number of pole pairs is doubled, the speed will be reduced by half, otherwise the purpose of speed regulation will be achieved.

This speed regulation method is phased, can not smooth speed regulation, and is only suitable for squirrel cage motors. The greater the pole logarithm refers to the larger the lifting base, the lower the rotational speed.

The difference between the double-layer winding and the single-layer winding of the AC motor is that the components are placed differently, the functions are different, and the characteristics are different.

1. The placement of components is different: only one component edge is placed in a slot in a single-layer winding, and two component edges are placed in a slot in a double-layer winding.

2. Different functions: double-layer windings that cannot be completed by single-layer windings can be done, such as fractional slots, pole changes, etc.

3. Different characteristics: less single-layer winding coil, relatively simple process; There is no inter-layer absolute Chang hidden because of the high utilization rate of the trough; The single-layer structure does not suffer from phase-to-phase breakdown failures. The disadvantages are:

The electromagnetic waveform generated by the winding is not ideal, the iron loss and noise of the motor are large and the starting performance is slightly poor, so the single-layer winding is generally only used in small-capacity asynchronous motors.

The advantages of double-layer windings are that suitable short-distance windings can be selected to improve the electromagnetic waveform, and fractional slot windings can be used to weaken higher harmonics. After using double-layer winding, the electromagnetic performance, force energy index and starting characteristics of the motor are better than those of single-layer winding. Two coil element edges are embedded in each groove in the core groove of the double-layer winding, when one coil edge of the coil element is embedded in the lower layer of a certain groove, and its other coil edge is placed in the upper layer of the other groove, the double-layer winding has two kinds of stacked winding and wave winding.

The windings of AC motors are divided into two types, double-layer windings and single-layer windings, and they have the following differences:

1.Structure: The double-layer winding is composed of two belts with alternating winding layers, and each winding layer contains a different lead coil. A single layer winding has only one winding layer, and the wire coils are continuously distributed over this layer.

2.Wire arrangement: The two stupid winding layers of a double winding have different wire arrangements, and they can be adjacent to the same polarity or adjacent to the opposite polarity. The conductor coils of a single-layer winding are arranged in a simple way, usually in the same polarity adjacent way.

3.Motor performance: The magnetic field distribution generated by the double-layer winding during the operation of the motor is more complex, which can improve the power factor and efficiency of the motor and reduce the harmonic content. The single-layer winding has a simple magnetic field distribution and has a strong harmonic response to the motor.

4.Wire break tolerance: Double-layer windings can remain partially operational in the event of a wire break on one layer. In the case of a single layer winding, the entire winding will fail if the conductor is broken.

In summary, the double-layer winding has higher motor performance and harmonic suppression ability than the single-layer winding, but its structure and manufacturing are also more complex, and the corresponding cost is also higher. In the specific application, the appropriate winding type is selected according to the requirements and performance requirements of the motor.

Summary. Hello, for you to find out: the single-layer winding is to place only one coil edge in each slot, because a coil has two sides, so the total number of coils of the motor is half of the total number of slots; The double-layer winding is to place two coil edges in each slot, and there is interlayer insulation in the middle distance, and the two sides of each coil, one is on the upper layer of a certain slot, and the other is in the base layer of other slots, so the total number of coils of the double-layer winding is equal to the total number of slots.

What is the difference between the motor slot and the motor coil, please send the master to ** with the word indication.

1.The stator slot of the motor is late for the winding pay-off coil, and the hidden Dan reputation is 2The number of slots is composed of the number of magnetic poles and the number of stoves for the embedded coil and the connection of related coils, 3The performance of the number of slots and the number of slots just forming the corresponding number of poles are basically the same.

Placing the coil groove is called a trunking.

Summary. Can the main and auxiliary windings of a single-phase motor be the same size?

The number of turns of the main and auxiliary windings of the single-phase motor depends on the role of the motor, how is the commonly used washing machine motor, its motor works in the forward and reverse state, and the wire diameter of the main and auxiliary windings is exactly the same as the number of turns. Because the secondary winding is the working winding when reversing, the main winding is the starting winding at this time. As a single-phase electric fan, the motor only has one turn, and the speed is adjusted by changing the number of turns of the auxiliary winding, so the number of turns of the main and auxiliary winding coils of the motor of this structure is different.

The main winding of the motor of this structure is generally thicker and the number of turns is less. The wire diameter of the secondary winding is thinner and the number of turns is also higher. The main winding is usually embedded in the stator slot first, in the outer ring of the winding. The secondary winding is generally embedded after the winding, in the outer ring of the winding.
