Q:Comparison between ac motor and dc motor
Alternating current is a frequency, usually with a power supply of 50HZ (such as China) or 60HZ (such as the us), with a voltage of 110V (such as the us) and 220V (such as China). Alternating current (ac) in China to 220 v, 50 hz access to power, his 50 hz frequency, can use ordinary power frequency transformer transformer (general transformer), more convenient, and direct current (dc) want to transformer, you need to use switching power supply, the switching power supply is very expensive, so for the power grid companies, the investment is too big. In addition, due to the power of the user, the phase voltage (voltage between the fire line) is 220V and the line voltage (voltage between the two different winding wires) is 380V On the high voltage side, the normal transformer input voltage is 10KV (kv) or 20KV 35KV, which is the main class, with 20KV most. Because of the high voltage transmission, according to the P = UI that power must be, the smaller the higher the voltage, current, and the current in the conductor can pass ability, is determined by the conductor cross-sectional area
Q:The type of speed adjustment of ac motor and the difference between them
There are three types of ac motor speeds common in industry. 1, the slip motor speed -- -- -- -- -- - on the motor output shaft is equipped with a pair of electromagnetic coupling, speed tests to adjust the magnetic field of the coupling with a set of speed. (not very much now, the disadvantage is inefficiency, the advantage is that it can be adjusted without speed.)
Q:What is the difference between the excitation winding of ac motor and the armature winding?
Exciting winding is the excitation winding magnetic field, the armature winding is the ac electrical output winding, for dc excitation synchronous generator excitation winding is the generator rotor winding, armature winding of generator stator winding.
Q:The ac motor with more than one kilowatt will be activated by the launcher
This there is no hard and fast rules, basically see your lines and transformers, as well as the requirement for the quality of power supply, and the line protection fixed value setting, general motor impact current when starting for the normal 8 and 13 times that of the large capacity motor can cause voltage fluctuations, for high precision processing equipment production can say deadly, so considering comprehensive factors above, a lot of places can choose soft start way start or frequency converter drive, I have seen more than 200 kw, 100 kw motor USES the soft start, specific also depends on the enterprise itself situation, generally more than eighty kw adopt soft start more.
Q:If you measure the temperature of the motor cover more than the environment temperature above 25 degrees, suggests that the rise of temperature of the motor is beyond the normal range, general motor temperature rise should be below 20 degrees. The general motor coil is made of enameled wire, and the enamelled wire will be flaked out by temperature over 150 degrees, causing the coil to short-circuit. But generally does not exceed 95 ℃.

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:Who made the world's first ac motor?
Notice, one is ac motor, one is ac generator, not one thing.I hope my answer will help you
Q:Which is better for a dc treadmill or an ac treadmill?
On electricity to run the market at present is dc motor, but the dc motor is ac motor, durable, safe, that is to say, market exchange treadmill will be dominant in the future. Running on electricity, suggest buying a running machine. If commercial electricity runs in clubs for a long time, then you have to buy an ac treadmill.
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:The calculation method of the weight of copper wire used for ac motor
It is often surrounded by a center, which has a high insulation layer. The cable has the characteristics of internal electricity and outer insulation.
