Tubular Motor for Awning Roller Shutter and Garage Door

Q:Is the ac servo motor self internal speed control: Can be internal direct speed adjustment, use dot move speed pattern, normally use PLC to send the PLS pulse, also can use a single chip machine of course

Q:The electric fan is a dc motor, or the ac motor is good, why?: Dc motors are generally small power, and the general power is communication. First of all, I want to correct a concept, no good questions, dc motor and ac motor is each have their own characteristics and purposes, there is no best motor, only the best manufacturers. That means that there's no better problem with dc motors and ac motors. Dc speed regulation is very convenient, as long as the voltage is changed, and the torque is not affected. Ac speed is more complicated and is known as a frequency changer. It is suggested that ac motor should be used, which is mainly used for ac motor, and dc motor needs a rectifier to work.

Q:The power consumption of a three-phase ac motor is equal to the line voltage cross current. How do you explain?: The formula for calculating the dynamical power of an electric machine: P = UI * square root of 3 * com. U: line voltage, which is what we call 308V, I: the phase current, and the phase current times the square root of 3, not the line current? Line voltage * current = electric motor is seen in power. If the actual power of the motor is calculated (in other words, how much electricity is used), it will also have to be the power factor and utilization.

Q:How the ac motor works: Ac motor consists of stator and rotor, what you said in the model, the stator is the electromagnet, the rotor coil. The stator and rotor is to use the same power supply, so the direction of the current in the stator and rotor changes always synchronized, namely the current in the coil direction changed, became the current in the electromagnet direction at the same time, according to the left hand rule, coil by magnetic direction invariable, the coil can continue turn. About the role of two copper rings, two copper rings with corresponding brush, can continuously is fed into the coil current. The benefits of this design are

Q:How do ac motors keep moving in the same direction?: Typically by capacitance phase out another phase Angle difference of alternating current (ac) effect on the secondary coil and main coil integrated into a rotating magnetic field up to cut off the secondary coil. As for the synchronous motor, the principle of some trouble, basic is asynchronous motor rotor into a rotor as dc motor. When it starts to become asynchronous start, starts in electricity, the rotor into sync, ha ha, also forgot to tell you that a speed ratio of the motor is rotating magnetic field of low speed asynchronous motor, the same is called synchronous motor, the speed of the rotating magnetic field is the synchronous speed.

Q:What happens to the capacitance of ac motor: The starting capacity of a single phase ac motor is not too large, and the oversize will cause the start torque Angle to deviate from the maximum, and the secondary winding current consumption increases. Too small to start the motor, the motor will not run for a long time!

Q:Ac motor 110KW how much current: But it's very short, so it's usually 1.3 to 1.7 times, and that's 1.5 times. You also have to think about the coefficient of use, and you take one of the motors. 223 * 1.5 * 0.9 = 301 A

Q:Three-phase ac motor star row and delta connection?: The design of this circuit is still controlled by the principle of time. The difference is that when starting the motor stator windings into star, each phase winding withstand voltage of power supply phase voltage (220 v), reduces the starting current impact on power grid. In its late starting, it according to the setting time for pick up in advance to delta connection, each phase winding withstand voltage of the power line voltage (380 v), into the normal operation of the electric motor. This kind of circuit is available for the squirrel-cage asynchronous motor, which is connected to a triangle in normal operation

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:How to change ac motor to dc motor: Application: dc motor and ac motor structure first, dc motor has a commutator (two half a copper ring), ac motor commutator. Dc motor is generally used in low voltage requirements of the circuit, dc power supply can be convenient to carry, such as electric bicycle is to use dc motor, and like a computer fan, radio cassette recorder motor etc. Difference method: the main thing is to see if there is a commutator, what power supply is used. The dc power supply for the commutator is the dc motor.
