Q:How does the motor select ac contactor: The communication contactor consists mainly of four parts: (1) electromagnetic system, including attracting coils, moving iron core and static iron core; (2) the contact system, including three main contact heads and one to two sets of regular open, often closed auxiliary contacts, is connected to the moving iron core. (3) an arc extinguishing device, which has a general capacity of communication contacts with an arc extinguishing device, so as to cut off the arc of the arc rapidly, avoiding the burning main contact; (4) insulation case and accessories, all kinds of spring, transmission mechanism, short circuit ring, terminal column etc.

Q:How does ac motor speed control: Ac motor is not adjustable and should be added converter.Electromagnetic coupling. It is used only for slip motors. By changing the current of excitation coil, the mechanism is simple, but the control power is small. Do not operate at a low speed.

Q:How to control the start-stop of 220V ac motor with a single chip? What type will you use for the relay: First, the control signal is used to decouple the output, which is amplified by the current to drive the relay. The relay type is chosen according to the size of the motor.

Q:According to the power of motor, how to select the contactor and switch?: Must first determine the breaking current, the general low voltage bus bar breaking capacity above 500 kva transformer with 50 kA switches, small transformer low voltage busbar can use 12.5 kA and the breaking capacity of the switch. Secondly according to the current power calculation, and generally current = power/voltage/power factor, if the three-phase motor is divided by 1.732 (because of calculation is single-phase current), choose the rated current higher levels of switch and the contactor. Then select the corresponding tripping characteristics depending on the type of load switch (including tripping accessories), feeder switch will generally choose electromagnetic, should choose the thermomagnetic motor switch type, high perceptual load should choose high grade tripping characteristics of the switch.

Q:Does the train use dc or ac?: Alternating current (ac) in 48 v the following safety voltage range Can form loop with a line. A line of fire, tracks or earth is zero. 48 v alternating current (ac) is not allowed above the earth or other bare conductors as the zero line is based on the safety of think. More than 48 v ac voltage, if zero line bad earth contact naked outside zero to get an electric shock accidents. I don't know much about electric motors on the railroad. I haven't seen anything like that. Sorry.

Q:How do ac motors keep moving in the same direction?: There are books in the book. Do you mean to change direction and change direction? Ac motor subrotors and stators The current changes in two current directions It's going to change the same way

Q:What are the similarities and differences between the dc brushless and the ac brushless motor?: General use on the generator excitation, brushless dc brushless ac motor is generally, also have a plenty of a brush, a motor is generally small motor brush, because of the need to solve the short circuit current of commutation time, so communication has the motor will not be too big, just imagine the dc motor, dc motor and reversing problems, so the dc motor will not do! Dc brushless motor actually is ac motor, commonly used in generator excitation system!

Q:Current ac motor has completely replaced dc motor: Definitely not. The performance of dc motor speed system is better, the advantage is that it can achieve smooth and economical speed adjustment, high precision and wide application. The speed adjustment of dc motor does not require the cooperation of other equipments, but by changing the voltage/current of the input, or the excitation voltage/current to speed the adjustment.

Q:Three-phase ac motor star row and delta connection?: Three-phase winding delta connection Three-phase asynchronous motor winding delta connection, when the power of a phase (L3) circuit, by the winding with cz series and winding ax again after parallel hybrid circuit of stator current whether meet the phase condition, the need to be calculated to determine. Because of the three-phase symmetric winding structure, the three-phase excitation impedance is equal, namely, Zma = Zmb = Zmc = Zm < Φ, the three phase stator current are: A = 0 12 / (Zm < Φ) = < - Φ, 0 = 0 c = 12 b/(2 Zm < Φ) = / 2 < - Φ. The current in the three-phase winding is visible, but the current phase is the same, and the current is not satisfied with the phase condition. Three-phase winding delta connection, three-phase asynchronous motor open phase, not only unable to start, lacks when starting the stator current is very big, if not in time to cut off the power supply, motor will be destroyed immediately. This is quite different from normal starting and must be taken seriously.

Q:What effect is the capacitor on the ac motor?: Start the capacitance to generate an electrical Angle in the moment the motor starts, producing a rotating magnetic field. The capacitance does not work after normal operation
