Q:The armature windings of large and medium-sized ac motors are often double-spaced
Because general winding when using single-layer windings, most (not all) cannot form a short distance, but the whole distance, the motor can effectively weaken the high order harmonic. The double winding will solve both problems.
Q:What are the advantages of the dc welder and ac welder? The better one?
The current of the dc welder is not "over zero", it is not easy to break arc, the arc is stable, this is its greatest advantage. The secondary voltage peak of transformer is certain, the dc arc welding machine is higher than the ac welder, it is easier to draw the arc. The dc welder is more than the ac welder, and the cost is slightly higher
Q:About 100W ac motor is better than dc motor
The answer is very specific. Ac motor and dc motor are used for different purposes, you can reconnect according to the theory, the industry experience of your relevant industry is applied. That would be better.
Q:What is the difference between a three-phase synchronous motor and a three-phase asynchronous motor search
We know that the three-phase power supply phase phase difference is the voltage on the phase between 120 degrees, three of the three-phase asynchronous motor stator winding on the spatial orientation also sent 120 degrees, so that when zhongtong into the three-phase power supply in the stator winding, stator windings creates a rotating magnetic field, the stator windings creates a rotating magnetic field, rotor conductors (cage) will cut the lines of magnetic force of a rotating magnetic field and induced current, the current in the rotor conducting bar and interact with a rotating magnetic field to produce electromagnetic force, electromagnetic force produced by electromagnetic torque drive rotor rotating magnetic field along the direction of rotation. In general, the actual speed of the motor is below the rotational speed of the rotating field. We call the three-phase motor an asynchronous motor. Three-phase synchronous motor is the three-phase generators of different working condition. There are N on three-phase synchronous motor rotor of magnetic pole, the pole to N - S - N - S - order, coil magnetic poles, all of the coil in series, the final ends, pick up on the rotor shaft of two copper on the slip ring, copper slip ring and the shaft is insulated.
Q:Is the motor for general electric tools ac motor or dc motor?
In general, it is a series of motor, so it is ac motor. Dc motor is used to drive the charging tool using dc motor. And the three-phase machine, like the concrete vibrator, is a three-phase machine. If it is a direct current supply, there must be a rectifier power supply, because the power supply is 220V, which must be fully dc to be used. The commutator, it is recommended that you baidu, because this is involved in the electric road map and so on, and some basic knowledge of the motor, which is not difficult to do.
Q:What is the control speed for ac servo motors?
It is estimated that you should use an external pulse control servo driver, and you can control the speed of the servo motor by controlling the frequency of the servo drive pulse. Japanese general maximum speed corresponding to the pulse frequency of 500 k by the proportion relation, you change your pulse output frequency of the controller, to control the speed of the servo motor.
Q:Can a converter drive a normal three-phase ac motor?
It is. For example, the motor is working in low-frequency areas, and the motor may be damaged by heat dissipation. If the motor is working in the medium-high frequency area, the ordinary motor can also use the frequency converter. Also, it is the insulation problem of ordinary electric motor, the proposal is to install output reactor. Of course, it's not necessary.
Q:Permanent magnet motor is dc motor and ac motor
Because ac motor requires changing magnetic field, such ability and the frequency of the alternating current (ac) together to make the rotor rotation, so the ac motor may not use a permanent magnet. The magnetic field of dc motors can be constant, so you can use permanent magnets.
Q:How does ac motor winding be classified?
There are many kinds of ac motor winding, which are divided by phase and single phase and three-phase winding. It has a single layer winding and a two-layer winding. The single layer winding is the same type, single chain, cross chain and cross. Double layer winding and wave winding; The number of slots in each phase of each phase is an integer or a fraction, and there are two forms of slot and fraction. But the principles of the winding are consistent.
Q:How the ac motor works
The principle of ac motors: the coils spin in the magnetic field. Do you know the principle of direct current electromotor? Dc motor commutator is used to automatically change the direction of the current in the coil, so that the coil stress direction is consistent and continuous rotation. So as long as the guarantee coil stress direction is consistent, continuous rotary motor will be. Ac motor is the application of this.
