Q: Does the step motor belong to ac motor or dc motor?: There are also dc and communication points for the server motor. The step motor should be a dc motor, because he is driven by a dc pulse.

Q: In the ac motor, he is excited, excited, and excited. What is the difference between: Series, the stator coil and armature coil in series, with a power supply, the characteristics of the motor is more soft, speed with load up and down is large! Shunt, stator coil and armature coils in parallel, is also a power supply, and the characteristics of the shunt motor is hard, he is not adjustable of mechanical and electrical properties, that is to say, his speed and torque along with the change of load is not big, but to prevent the loss caused by the speed, must have protection circuit.

Q: The rated current of a single phase ac motor is several times that of an empty current.: The general situation depends on the power of the motor: the low electric current can reach 60% of the rated current and even higher. Large electrical current is normally only about 25% of the rated current. The three-phase motor is five to seven times direct start-up, three to five times the voltage drop, and the three phase motor is seven times the current. Single phase motor is 8 times.

Q: Why does dc motor reduce the voltage regulating ac motor?: The magnetic field of the dc motor is generated by the excitation current through the magnetic pole coil, which has a stable magnetic field, so changing the armature voltage can change its speed. Ac motor can also use dropping speed, but the range of speed regulation is very small, mainly its magnetic field is produced by the power supply current, change the voltage, the magnetic field also changed, so a lower voltage, its torque is proportional to the square of the voltage, torque declines very quickly, so the speed range is very small, also reduces the load ability, therefore ac motor generally don't dropping speed.

Q: Is it still a communication welder: Generally speaking, the ac welder appears on the market, the more common is the manual arc welding series, such as: BX1...

Q: Dc brushless motor and ac motor: The dc motor is for direct current, but the coils inside the rotor are still alternating current circuit. A dc motor with a brush is replaced by a brush. Instead of a brush motor, the dc is converted into ac by a contravariant circuit and then coiled to the coil. The common one is the 12V cooling fan. It is commonly used in computer servers. Ac motor does not need a commutator (brush). Normally no permanent magnet is needed. ... To learn more about buying an electric machine, read it

Q: What are asynchronous motors and synchronous motors: The difference between asynchronous motor and synchronous motor is that rotor speed is different, the rotor speed of asynchronous machine is less than synchronous speed, and the rotor speed of synchronous machine is synchronous speed. Note: in the asynchronous machine, there is a rotating magnetic field at the same speed as the synchronous speed, the synchronous velocity is 60f/p, f = 50hz, and p is the logarithmic logarithm. Further excitation of the rotor of the synchronous machine; The asynchronous machine is not used, and can directly from the stator to the rotor.

Q: Ac asynchronous generator principle: In structure, a generator is identical to an electric motor, which is usually composed of stator, rotor, end cover, and the electric brush. The stator is composed of the machine seat. Stator iron core, wire wrap winding, and other structural parts that are fixed in these parts. The rotor by the rotor iron core, the rotor pole (with magnetic clutches. Pole winding), slip ring, (also known as the copper ring collector ring.), such as fan and shaft parts. Generators and motors is completely reversible, and motor stator with rated voltage of the generator, the rotor will rotate, generator or motor rotor rotation by external force, to achieve synchronization of rated speed, the stator can produce voltage, produces electricity. The working principle of three phase asynchronous motor, three-phase alternating current motor stator winding into the three-phase alternating current, can produce a rotating magnetic field, rotating magnetic field lines is put through the stator core, air gap and the rotor iron Yi constitute a loop. Asynchronous motor rotor winding conductor due to the motion, the relative to the rotating magnetic field is induced electromotive force by cutting lines, and thus will through the rotor winding current. The rotor winding conductor of a current-carrying current is affected by electromagnetic force in the rotating magnetic field. Under the electromagnetic torque of electromagnetic force, the motor rotor moves along the side wind of the rotating field.

Q: Does ac motor use the upper hall sensor: There is little protection in domestic electric motors. Ordinary asynchronous induction ac motor does not require a general hall sensor. If you can monitor the speed of the motor, consider it.

Q: What will be the result of the power supply to ac motor after the rectifier (not filtering)?: Ac motor can't move, but it will heat up because of the problem of electrical phase.But the voltage is unstable, not like direct current, so the torque is unstable, which is to say, it's not safe. There may be frequent blocking or crawling, and the damage to the motor is very large.
