Q:How the ac motor works
Avoid to avoid the second power cord around the problem, because the coil is continuously turn, use two wires to the coil power supply, the power cord will avoid around about the current in the coil is due to alternating current (ac), there is a time of current is equal to zero, but this time with the current time is too short, what's more, the coil quality, with inertia, due to the inertia coil will not stop. Ac motor is according to the characteristics of alternating current (ac), to produce a rotating magnetic field in the stator winding, and then make the cutting rotor winding magnetic induction line movement, make the rotor winding induced current, the induced current in the opposite direction of the induced magnetic field and stator magnetic field, to make the rotor has the rotary torque.
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 electric spark machine USES ac motor or dc motor!
The upstairs talk is too absolute. The control mode of the spark machine is relatively simple, and the power of the motor is smaller, under 100W. Most electric spark machine is made of dc servo motor and electronic ruler.
Q:How does a three-phase ac motor form a circuit?
The principle of a three-phase motor is; The three-phase winding of the motor are 120 degrees apart in space, in the three phase line differ by 120 degrees electric horn three phase alternating current A rotating magnetic field, can be born, in under the action of electromagnetic induction, the rotor rotation. The three-phase alternating current, which is itself three circuits, is not necessary to use a zero line because of the uniform load. A - B, c. B - A, c. c-a, B
Q:Which is good for dc motor and ac motor?
The family seems to be alternating current, so it should be alternating current. Direct current also seldom listens
Q:Single phase single capacitance ac motor three wires wrong
The single phase motor is divided by the main winding and the starting winding, and the wrong turn can also be turned, but the electric opportunity quickly overheat and damage, the proposal to seek a professional to show you.
Q:The structural difference between ac motor and dc motor
direct starting startup slip is 1, rotor induction electromotive force is very big, the rotor current is very big also. When under the rated voltage of the motor starting, referred to as direct start and direct start current of about 5 to 7 times of the rated current. In general, under the rated power is 7.5 kw small capacity of asynchronous motor can be directly starting. Direct starting control circuit used appliances including combination switch, button, intermediate relay contactor, thermal relay, and fuse. Mastering their respective characteristics, at the same time grasp the fuse fuse rated current calculation. Starting control circuit directly: to grasp its control principle. (2) the squirrel-cage asynchronous motor step-down starting. Master star - Angle starting and autotransformer step-down starting the work principle of (3) the wound rotor three-phase asynchronous motor starting General understanding. 6. The three-phase asynchronous motor and reversing control Generally understand 7. Three phase asynchronous motor speed regulation This part is important, to understand the formula. Changing the rotational speed of the motor, there are three possible change frequency and change the winding of magnetic pole logarithmic or change slip. 8. Synchronous motor
Q:Do you start the coils when you are communicating?
In addition, the resistance split-phase motor (such as thermal resistor start refrigerator motor), after the start, resistance value is very big, can think of the coil is power, does not work.
Q:In the ac motor, he is excited, excited, and excited. What is the difference between
He is excited to have another power supply excitation coil (stator coil) Series of excited, stator coils with armature coils And excitation, the stator coil is in parallel with the armature coil
Q:Calculation method of motor torque
The relation between power, speed and torque is not related to motor form. All the rotating machines are the same. The formula is P = T * n / 9550, P is power, unit KW, T is torque, unit N.m, n is RPM, unit RPM. Different types of motors have different output characteristics, and there is no way to do the exact equivalent, mainly for use.
