Q:AC servo motors generally choose synchronous or asynchronous?
It seems that there are asynchronous servo motors, but the synchronous servo motors are used in the market.
Q:The difference between three-phase AC synchronous motor and three-phase AC asynchronous motor
The stator windings of synchronous machines and induction motors are the same. The main difference is the structure of the rotorThere is a DC exciting winding on the rotor of synchronous motor, so the external excitation power supply is needed, and the current is introduced through the slip ring;The rotor of the induction motor is short circuited winding, which generates current by electromagnetic inductionAsynchronous motor has the advantages of simple, low cost, easy to install, use and maintenance. It is widely used. The disadvantages of low efficiency, low power factor of power grid and high efficiency disadvantage. Synchronous motor is a capacitive load, can improve the power factor. With large mining equipment.
Q:The difference between induction motor and induction motor
. a three-phase induction motor is an induction motor, the induction current definition: formed by the rotating magnetic field of stator winding and rotor winding of the magnetic field from the interaction of electromagnetic torque of AC motor drive rotor rotation.
Q:Why is the rotor of an AC motor neither magnetic nor can it rotate?
The DC motor and AC synchronous motor works as follows: the stator or rotor produces a rotating magnetic field, while the secondary winding forms polarity. Since the two poles of the stator and rotor are attracted or repelled by each other, the rotation is generated.
Q:How to change DC motor to AC motor?
DC motor change to AC motor, mainly for the control part of the change.1, AC control system speed, must be installed inverter, motor also choose AC inverter three-phase asynchronous motor.2, three-phase alternating current frequency is 50Hz, synthesis magnetic field synchronous speed is 50r/s, namely 3000r/min, if the motor more than one pair of magnetic poles, further analysis can also get synchronous speed.3 and 4 pole synchronous speed is 1500r/min, 6 pole synchronous speed is 1000r/min, 8 pole synchronous speed is 750r/min, and 10 pole synchronous speed is 600r/min.
Q:The difference between AC motor frequency conversion speed regulation and voltage regulation speed regulation
Voltage regulation: smoothness is good, speed range is narrow, can not be used for constant load speed regulation.
Q:AC motor control chip
Alternating current machine: a machine used to realize the mutual conversion of mechanical energy and alternating current energy. AC motor has become the most common motor because of the great development of AC power system. Compared to the AC motor and DC motor, because there is no commutator (see DC motor commutation), therefore has the advantages of simple structure, convenient manufacture, relatively strong, easy to make high speed motor, high voltage, high current, large capacity. The coverage of AC motor power greatly, from a few watts to several 101000 watts, even millions of kilowatts. In the early 1980s, the largest turbo generator reached 1 million 500 thousand kilowatts. The [1-2] AC motor was invented by Nicola Tesla, an American scientist from Serbia.
Q:The difference between a direct current motor and an alternating current motor
As the name suggests, the direct current motor uses DC as the power supply. AC motors use alternating current as power source. Structurally, the principle of the direct current motor is relatively simple, but the structure is complex, and it is not easy to maintain.
Q:AC operation of AC motor control circuit must be used?
When the current through the coil, in under the action of the permanent magnet, through attraction and repulsion when it rotates, and to balance the magnet, the original electric line is corresponding to contact the commutator and brush and brush away, connected to the group with the impulse to coil contacts should be so, repeat it, DC motor will turn up
Q:How is the rated current of three-phase AC motor calculated?
I=S/1.73UX0.8 is: apparent power divided by the square root of 3, 1.73, and then divided by the voltage X power factor 0.8
