Q: How do I get 220v on the motor?: General three-phase motors are industrial motors, are generally three phase voltage of 220 v / 380 v, to meet the domestic load single-phase 220 v I suggest you can add a single-phase 220 v input of inverter, the inverter output voltage is 220 v three-phase can be received on the delta connection of three-phase motor. Dongguan city motor company technical staff told me.

Q: Which price is higher for ac motor and dc motor? Which service lasts longer?: In the premise of the same capacity, because of the low sales of the dc motor and the quantity of copper, the price is more expensive than the ac motor. 2 because of the dc motor brush need to replace frequently, if included in its life, the working life of the dc motor is ac motor is short, if not included in the replacement of the working life of the brush, the life of the two kinds of motor is basically the same

Q: What does the motor center of the three-phase ac motor mean: Center height refers to the height of the motor shaft to the base Angle of the seat. The length of the machine is used in the international letter of the letters: the "S" - the short stand, the M - the engine seat, the L - the long machine seat, is usually determined according to the length of the stator iron core. The "H" of 80 is 80mm

Q: Is the synchronous motor not communicating? Why do you say that brushless dc is a type of synchronous motor? Exclude o: Ontology is an alternating current, motor also similar, but the dc supply is converting ac square-wave brushless motor winding, permanent magnet synchronous motor is to convert alternating current (ac) to supply sine wave with motor winding. It's just electrical control. Can't see from the outside!

Q: What is excitation, excitation current, what is the difference between motor and generator: The excitation current is provided by the independent power supply for the motor excitation winding. For example, the use of an independent dc power source for the excitation winding of a dc generator; The electromagnetic field of the armature winding of the asynchronous motor is generated by ac power supply. The former is the dc excitation, the latter is the exchange excitation. Synchronous motor according to the situation of the power grid, can be a rotor field winding dc excitation, can also be provided by the grid ac excitation on the stator, the general is given priority to with dc excitation. If the dc excitation is insufficient, then the reactive reactive current from the grid input is added to the motor. If the dc excitation method is overused, the motor will output the backward reactive current to the grid, weakening the internal magnetic field of the motor. When the dc excitation is adopted, the voltage drop in the excitation circuit is only caused by the resistance, the excitation voltage is low, and the excitation power supply is small. With the use of ac excitation, the excitation voltage is much higher, and the capacity of excitation power supply is much higher.

Q: What is the difference between dc, alternator motor, and how the motor works: At present, the most common generator in the country is a fixed coil, which makes the two magnetic poles rotate so that the inductance current (alternating current) is generated. When you generate electricity, you're cutting it, and you're not cutting it unless you stop working.

Q: The same power ac motor is more expensive than the dc: Of course, dc is expensive, dc motor is much more complicated than the three-phase squirrel-cage ac motor.

Q: Calculation method of motor torque: There is a formula for your problem: Electrical power: P = 1.732 * U * cos phi Torque: T = 9549 times P/n; Power torque = 9550 * output power/output speed Torque = 9550 * output power/output speed P = T * n / 9550 The formulas The relationship between motor power, torque and speed Power = force * velocity

Q: What are the main parts of alternators?: ?ends of the generator is aluminum alloy die casting, after the end cover with brush holder. Silicon diode rectifier is used will have a three-phase alternating current generator, rectifier dc. It is composed of six diode, respectively, pressure plate and the rear end cover in aluminum alloy component, a three-phase bridge rectifier circuit. x0d generator of the cathode by iron, perfectly on the back end cover three diode cathode tube, its shell is positive, three diode shell together become a generator of the cathode, the center for pipe cathode lead; In a component on a board of three diode as the anode tube, its shell is negative, the three diode shell meet together for the anode, the center lead to the anode of the pipe.

Q: Do you start the coils when you are communicating?: In the work of single phase ac motor, there are also two kinds of conditions for starting coils. The electric motor with "shake", the electric motor of the refrigerator, the starting coil is without power and no work.
