Q:Dc motor power 13KW for ac motor
The dc motor and ac motor are not allowed to be exchanged for each other. This is because the external properties of dc motors and ac motors are very different, and the relative information will be known. If direct substitution is used, it will directly affect the mechanical properties and the life of the motor. But as a technical reform project, there are also successful cases. The first priority is to give the torque to the mechanical requirement, and to match the power, check the manual and check it out.
Q:Why does the motor need capacitance when the machine starts?
In the picture, a positive reverse circuit is shown, and the switch hits the "positive" in the upper part of the circuit. The switch hits the bottom "inversion" to connect the capacitor to the upper one. There is no need to think about capacitance charges.
Q:What is the difference between the excitation winding of ac motor and the armature winding?
Motor learning definition "armature" as the "main power circuit", as long as you think about the power of the stator loop or rotor circuit of large power, the big is the armature. The power is the voltage X current. Only the synchronous generator and the synchronous motor have excitation winding and armature winding. The general ac asynchronous motor is not excitation winding. Squirrel-cage asynchronous motor points and winding type two kinds big, the same stator winding structure, the squirrel-cage rotor cage bar, wound rotor rotor coil is an external device (can change the rotor impedance to realize variable speed). The "armature winding" is the "main power circuit" of the motor. Which power of the rotor and stator coil is "armature", needless to say, most stator coils are "armature winding".
Q:What is the general ac motor in electrical design?
It is mainly based on the characteristics of the circuit and the load, investment, etc
Q:What is the difference between asynchronous and synchronous in the three-phase motor?
The so-called synchronous motor is the rotational speed of the armature winding, which is the same as the rotation of the rotor. Such an electric motor is typically made of a winding on the rotor and a concentrated excitation winding. No winding on the rotor, and the permanent magnet structure; The rotor has no winding, no permanent magnet, tooth and groove. There is a distributed winding on the stator. The use of such structures is to minimize the number of slides and brushes, which are called refield motors. There is also a special requirement for the excitation winding to be placed on the stator, which is commonly referred to as the armature type (such as the home ceiling fan). There is a big difference between asynchronous motors and synchronous motors: The work of synchronous motor depends on "the magnetic field is always in the shortest direction of the magnetic circuit", for example, in the case of the lost motor. After excitation on the rotor, N and S are present. And then the stator field is rotating, and its N, S polar interchanges, always correspond to the magnetic poles on the rotor. So it's in sync. More importantly, the magnetic poles of the fixed and rotor must be the same, otherwise the machine won't work.
Q:How do I get 220v on the motor?
If is to first of all should be low voltage motor step-down, dc motor need rectifier, filter, as needed if in ac motor is single-phase motor can be directly connected to the domestic load, is a set of three-phase motor single-phase electric into three-phase electric equipment. However, the typical three-phase motor is an industrial motor, directly connected to the industrial three phase electricity, while the civil motor is mostly dc motor or single phase motor.
Q:What is the difference between dc motor and ac motor?
The dc motor is the magnetic field, which is moving in the field. Ac motor is a magnetic field rotating motion, while the conductor does not move. Dc motor are divided into stator winding and rotor winding. The stator winding magnetic field is produced. When general dc. The stator winding is fixed polarity of the magnetic field generated. The rotor flux direct current in the magnetic field force. The rotor in the magnetic field force then spin. Direct current institutions to build complex. Cost is high. Ac motor stator winding and rotor conductors. Shaped like a squirrel cage rotor conductors between conductors and conductors with silicon steel sheet. Also have some ac motor rotor windings.
Q:How to distinguish dc motor from ac motor?
The difference between dc motor and ac motor is, of course, the type of power supply. One is dc and one is communication. The stator of a dc motor is a fixed magnetic field, and the direct current is rotating within the stator by the electric brush of the rotor forming a changing magnetic field around it. In industrial enterprises, dc motors are generally used for standby machinery or security equipment that can be reliably run because of the relative reliability of dc power sources. As the input voltage changes due to dc motor speed can also change, so need to often speed used dc motor is also many, such as trolley, electric locomotive, and so on. Ac motor is the rotational force generated by the rotating field of the stator that inducts the electric potential on the rotor. Its speed is generally fixed. But because of its simple structure and convenient power supply, it is widely used in various enterprises and families. Small to household washing machine, vacuum cleaner, big to huge pump, machine tool and so on, all use ac electric machine. Since communication is easier to obtain and easier to deliver, most of the electric machinery we use today is driven by ac motors.
Q:When the ac servo motor is turned off, the rotor shaft is tight
When the ac servo motor is out of power, the shaft of the rotor shaft is very tight: Since the servo motor is the brake device, the motor is not moving when the power is off. If there is no brake device, it indicates that the load is not installed properly, which can cause rotational difficulty. Solution: loosen the load and turn the motor separately.
Q:What is the regulation method of ac motor? What are the different features
The larger the resistance, the lower the speed of the motor. This method is simple and easy to control, but the switching power is used in the form of heating. It is a kind of speed adjustment, and the mechanical properties are softer. Control method: change the stator voltage of the motor to achieve different speeds. Because the torque of the motor is proportional to the square of the voltage, the maximum torque decreases a lot, and its speed limit is small, which makes the general cage motor difficult to apply. In order to extend the range of speed adjustment, the speed adjustment speed adjustment should adopt the cage motor with large rotor resistance value,
