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:24v motor, do not know whether is dc or ac, how to judge
You can take a magnet and you can take a magnet which is very close to a motor and it's a repulsion and that's a dc motor. Because the small dc motor is the magnet. Ac motor only absorbs
Q:What are the requirements for frequency conversion of ac asynchronous motors?
harmonic caused by unbalanced magnetic circuit and electrostatic induction, etc., in the shaft end or between shaft and bearing of shaft voltage than when big sine power supply, if the axis of the shaft voltage current is large, will cause great harm to bearing parts such as motor, seriously affect the safe and stable operation of the machine. An insulating design is needed for bearings. The motor of variable frequency control is no longer running at fixed frequency points. But in a more wide frequency range, electrical parameters and operation characteristics changes with the change of frequency, at the same time because the motor operating frequency range is wide, if poorly designed, the resonance frequencies of the power supply into the resonance frequency range of the motor, the motor may be strong vibration. The cooling capacity of the motor is reduced when the motor speed decreases, and the heat dissipation of the motor at low speed must be considered. 5, for constant speed operation of the motor, rating and selection of optimal working point is simpler, load characteristic of the motor is according to the rated operating conditions to consider commonly, for motor frequency control of motor speed operation, different speed running condition is different, so the rating and selection of optimal working point is a complex problem.
Q:The motor in the hair dryer is ac motor, or dc motor
Dc permanent magnet motor。Dc motor, series diode rectifier. Please adopt!.I hope my answer will help you.
Q:In the ac motor, he is excited, excited, and excited. What is the difference between
Series, the stator coil and armature coil in series, with a power supply, the characteristics of the motor is more soft, speed with load up and down is large! Shunt, stator coil and armature coils in parallel, is also a power supply, and the characteristics of the shunt motor is hard, he is not adjustable of mechanical and electrical properties, that is to say, his speed and torque along with the change of load is not big, but to prevent the loss caused by the speed, must have protection circuit.
Q:What is the electrical Angle in the motor? What does it have to do with mechanical angles
For polar motor, the stator inner circle of power Angle and the mechanical Angle is equal to 360 °; And p on the pole motor, the stator inner circle electric all Angle is 360 ° p, but still mechanical Angle is 360 °. So there is a relationship between the two: Electrical Angle = mechanical Angle times logarithmic
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:What are the advantages of the dc welder and ac welder? The better one?
The current of the dc welder is not "over zero", it is not easy to break arc, the arc is stable, this is its greatest advantage. The secondary voltage peak of transformer is certain, the dc arc welding machine is higher than the ac welder, it is easier to draw the arc. The dc welder is more than the ac welder, and the cost is slightly higher
Q:The voltage must be, what is the speed of the motor
Ac motor speed: N/p = 60 * f1 In formula one, the frequency of alternating current; P is the logarithm of the rotational pole; It has to do with the number of turns of the coils The alternating current of ac motor is related to the frequency. Related to the number of turns also. If again on the basis of the original coil around some coil is equivalent to a series inductance, the inductance antihypertensive effect. So the speed is low. Some electric fan is to use the tap coil to adjust speed.
Q:What is the control speed for ac servo motors?
It is estimated that you should use an external pulse control servo driver, and you can control the speed of the servo motor by controlling the frequency of the servo drive pulse. Japanese general maximum speed corresponding to the pulse frequency of 500 k by the proportion relation, you change your pulse output frequency of the controller, to control the speed of the servo motor.
