Q:The armature windings of large and medium-sized ac motors are often double-spaced
Because general winding when using single-layer windings, most (not all) cannot form a short distance, but the whole distance, the motor can effectively weaken the high order harmonic. The double winding will solve both problems.
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:What is the classification of ac motor?
The three-phase asynchronous motor is the most widely used in the two kinds of rat cage and winding type according to the different rotor structure.
Q:What is the difference between ac motor and dc motor?
We know that the three-phase power supply phase phase difference is the voltage on the phase between 120 degrees, three of the three-phase asynchronous motor stator winding on the spatial orientation also sent 120 degrees, so that when zhongtong into the three-phase power supply in the stator winding, stator windings creates a rotating magnetic field, the stator windings creates a rotating magnetic field, rotor conductors (cage) will cut the lines of magnetic force of a rotating magnetic field and induced current, the current in the rotor conducting bar and interact with a rotating magnetic field to produce electromagnetic force, electromagnetic force produced by electromagnetic torque drive rotor rotating magnetic field along the direction of rotation. In general, the actual speed of the motor is below the rotational speed of the rotating field.
Q:How to control ac motor with single-chip microcontroller
Control methods: The output of a single chip machine is connected to a photoelectric coupler, combined with a triode and relay circuit. To see how much voltage the relay corresponds to, one end of the relay has to be connected to the voltage, and the other end to the triode. 3, one end of the relay is suitable for alternating current voltage of ac motor, and ac motor at the other end. Two relay control for positive and reverse transfer. In simple terms, the small relays are controlled by the output of a single chip, the small relays control motor
Q:How the ac motor works
Avoid to avoid the second power cord around the problem, because the coil is continuously turn, use two wires to the coil power supply, the power cord will avoid around about the current in the coil is due to alternating current (ac), there is a time of current is equal to zero, but this time with the current time is too short, what's more, the coil quality, with inertia, due to the inertia coil will not stop. Ac motor is according to the characteristics of alternating current (ac), to produce a rotating magnetic field in the stator winding, and then make the cutting rotor winding magnetic induction line movement, make the rotor winding induced current, the induced current in the opposite direction of the induced magnetic field and stator magnetic field, to make the rotor has the rotary torque.
Q:Is it still a communication welder
Never put off till tomorrow what you can do now promotion of inverter dc welding machine and high recognition are very popular, and in recent years the development of the quality of welding inverter also promoted to a higher level, failure rate also fell dramatically; The welding performance of the inverter welder is much better than the ac welder, so its market share is higher (compared to the ac). And in other series of welders (e.g., argon welding, square wave alternating current, gas welder, plasma...) The reverse welder's share is higher
Q:What is the starting method of ac motor?
Start with 2. Star - triangle start. 3. Extension start. 4 drop press start.I hope my answer will help you.
Q:How does dc motor change ac motor
But between dc motor and ac motor can't convert each other, this is because their manufacturing process and machine structure is different, the design from the start then can not be changed, unless you have taken apart the motor to have done
Q:What kind of motor can be added
Speed regulating motor (220 v) : the speed controller adjustable speed range: 130 ~ 1350 RPM, with speed sensor, inside the feedback control, so the power frequency have change, it should have no change of revolution.
