Q:Three-phase asynchronous ac motor electric speed formula?: In China, the power frequency is 50 Hertz, so the synchronous speed of the dipole motor is 3000 RPM/min, and the synchronous speed of the quadrupole motor is 1500 revolutions per minute, and so on. The rotor of an asynchronous motor is always slower than or above its rotating magnetic field, and the name of asynchrony comes in. The difference between the rotor speed of the asynchronous motor and the rotational field speed (called the transvariation) is usually within 10%. Because of this, the actual speed of the three-phase asynchronous motor will be lower than that. If the synchronous speed of 6 is 1000 revolutions, the actual speed is 960 RPM/min.

Q:The difference between the permanent magnet motor and the permanent magnet synchronous motor: Motor is generally referred to as the motor and generator, because the word generator is only a few professionals involved, so people say that the motor is the motor, the electrical energy into mechanical energy. Permanent magnet motor has dc motor and permanent magnet ac synchronous motor.

Q:What is the control speed for ac servo motors?: Common way of servo drive speed have analog voltage control, namely by adjusting the servo drives the difference voltage at the input analog voltage control control servo motor running at different speed; Another is command control, which gives the servo the required speed through a given command. There is also a pulse signal control, which controls the speed of the servo motor through a pulse signal generator or another set of servo.

Q:What is the ac motor made up of?: Alternator is divided into two parts, the stator winding and rotor winding three-phase stator winding Angle of 120 degrees of electricity distribution according to the differences in the shell, rotor winding is composed of two pieces of a claw. When the rotor winding is connected to a direct current, the two polar claws form N poles and S poles. The line of magnetic force starts from the N pole, and enters the stator core through the air clearance to the neighboring S pole. Once the rotor rotation, the rotor winding will cut lines, mutual difference 120 KWH in stator winding sine electromotive force, the Angle of the three-phase alternating current (ac), through the six of silicon diode rectifier components into a dc output. As the output voltage of the generator increases with the speed of the engine, the voltage regulator should be adjusted to meet the need. The modern car's generators are compact, putting an integrated circuit regulator into a generator and filling it with a multi-tube form. For example, the xiali car generator has eight semiconducting tubes, six rectifier used only, the other 2 is used only for three-phase neutral point voltage rectifier output, so as to improve the power of generator.

Q:How does the three-phase ac motor achieve constant power or constant torque output: Is generally frequency converter to realize, in the power supply of power frequency 50 hz, motor with frequency converter to belt, the inverter output below 50 hz, the motor is constant torque output, but in the inverter output above 50 hz, the motor is constant power output

Q:Current ac motor has completely replaced dc motor: No matter Powerful electric cars can communicate without dc Small power hard drives, stripper motors in the optical drive, not all dc

Q:The alternating current is constantly changing, and how is the ac motor going to be controlled?: Ac motor direction of rotation is not determined by the alternating current (ac) plus or minus half cycle of direction, but by the alternating current (ac) through a certain way of dealing with the rotating magnetic field generated by acting on the rotor, just like you with a permanent magnet circle around the compass makes a compass as the principle of spin the rotor rotation, its rotation direction depending on the direction of the rotating magnetic field.

Q:What is the general ac motor in electrical design?: It is mainly based on the characteristics of the circuit and the load, investment, etc

Q:Ac asynchronous generator principle: Asynchronous generator rotor is higher than the synchronous speed, the stator magnetic field will be of induction coil cutting, voltage and current, if the power grid, the grid frequency control are the synchronous speed. If it is not incorporated into the grid, its synchronous speed will be determined by the combination of the generator's speed and load.

Q:Can alternator speed improve power generation?: From electromagnetic theory, rotor and stator is closely linked, active and reactive power generator are by the output of the stator, rotor torque decide the size of the active power and rotor winding dc current determines the amount of reactive power. In structure, a generator is identical to an electric motor, which is usually composed of stator, rotor, end cover, and the electric brush. The stator is composed of the machine seat. Stator iron core, wire wrap winding, and other structural parts that are fixed in these parts. The rotor is made up of rotor core, rotor magnet (magnetic coil), slide ring, (also known as brass ring), fan and shaft. The generator and motor are completely reversible, and the rotor is rotated when the voltage is added to the stator winding of the generator and motor. When the rotor of a generator or motor is rotated by an external force, the rotor is rated at synchronous speed, and the stator can generate a voltage and emit electricity. Just because the design has the focus, generator for motor or motor for generators, efficiency are below 70% of the rated, so generally will not replace, only small capacity will choose instead.
