Q:What does the D axis and the Q axis mean for AC induction motors?
The D axis and the Q axis represent the direct axis and communicate. By decomposing the stator current into the direct axis component and the quadrature axis component, the armature responses are calculated respectively so as to better control the stator currents.In permanent magnet synchronous motor control, in order to obtain similar control characteristics of DC motor,
Q:What are the differences between AC motors and DC motors?
DC motor installed a constant magnetic field, current in the stator coil of electromagnetic force is created, it will move, but the direction of the current to continue to change, so will the use of brush, contact terminals. Therefore, the cost of construction is relatively high. Generally used in servo motor, speed measuring motor and excitation motor more.
Q:What is the maximum speed of a three-phase AC motor?
This motor is divided into pole number, 2 pole motor synchronous speed 3000RPM; 4 pole motor synchronous speed 1500RPM; go down and so on
Q:Can AC motors be converted into generators?
Another method is to replace the original rotor directly with the one or two pole permanent magnet. Note: the poles of the permanent magnet should be as close to the stator as possible, but they cannot be touched. Rotating the rotor (or permanent magnet rotor) can pass the stator around the output voltage, current. If the speed is increased, the voltage can be mentioned very high.
Q:What is the reason that the single phase AC motor is turned on and off?
Check the switch first, is there any bad contact?. After the problem of the switch is removed, the power is turned on, and whether the cold state can run normally every time. If there is a phenomenon that the cold condition can not work properly, the internal circuit or winding is not working.A single-phase alternating current motor is a rotating electromagnetic machine used to realize the conversion of electrical energy and mechanical energy.
Q:How can a DC motor be changed into a three-phase AC motor with good performance?
Selection of asynchronous motor, power 60kW, voltage 400V, speed of only 960 RPM selectable (6 pole), if the speed is not enough to add speed (AC motor only 1500, 1000 (960), 750, 500 and several speed; if optional) must be 1000, as long as the election with step motor, just the price is too expensive.If the power supply capacity is not enough, without speed regulation, you need to calculate the starting capacity, select the starting mode and motor.The starting modes of squirrel cage asynchronous motor include direct start and star triangle startingThe above is cheaperThe starting modes of winding asynchronous motors are resistance start and frequency sensitive variable resistance starting
Q:Structure of alternating current motor
An alternating current motor is mainly composed of an electromagnet winding or a distributed stator winding and a rotating armature or rotor for generating a magnetic field. The motor is made by the rotation of the energized coil in the magnetic field.
Q:Are there 3 harmonics in the voltage of a three-phase alternator? Why?
If the generator is connected to the power supply system after the transformer is boosted up, and the transformer has a winding with a triangle connection, then there is no 3 harmonic in the generator outlet voltage
Q:How do ordinary AC motors brake?
Energy consumption brakingWhen the motor cuts off the AC power supply, a DC power supply is added to any two of the stator winding to generate a stationary magnetic field, and the stationary magnetic field is generated by the inertia rotation of the rotor to produce a braking torque.
Q:Why are electric hair dryers divided into direct current motors and alternating current motors? What are their differences?
DC motor: fast speed, light weight, simple structure, easy to damage, big sound making
