- Q: Single phase synchronous alternator working principle
- From the point of basic electromagnetic circumstance, a dc motor can be working for motor operation in principle, can also be used as a generator to run, are only different constrained conditions. On the two brush end of the dc motor, and dc voltage, input power to the armature, mechanical energy output from the motor shaft, drag the production machinery, become motor converts electrical energy into mechanical energy, such as prime mover drag dc motor armature, and without dc voltage on the brush, the brush end dc electromotive force can be drawn as dc power, output power, motor become generator converts mechanical energy into electrical energy. The same machine, which can be used as an electric motor or as a generator, is called the reversible principle in the theory of electric motors
- Q: Which price is higher for ac motor and dc motor? Which service lasts longer?
- Accurately, if is the same specification, should be ac motor price is low, service life is longer, through electromagnetic induction ac motor rotors, relatively save electricity, and the internal heat production is less than a dc; Dc motor, the electric motor turns the electric motor, produces heat fast, but the effect is better. Therefore, you should choose according to the requirements when using.
- Q: Is there a sensor in the electric forklift motor? If there is a failure, can the car still walk?
- Electric forklift truck technology has experienced from ac to dc, and returned to the change of communication, the earliest communication technology because of restricted by technology and electronic parts so no, later is popular, dc technology with ac motor, ac electric control, the development of the contactor gradually eliminate dc technology. The dc motor has a carbon brush, which is time-consuming and time-consuming to maintain, and because of the technical constraints, it is often the phenomenon of burning the electrical parts. And the communication technology has greatly improved the service life of the parts of the forklift truck, and the motor has no brush motor
- Q: Three phase ac synchronous motor is different from three-phase ac asynchronous motor
- Structure and principle of The stator winding of synchronous motor and asynchronous motor is the same, the main difference is the structure of the rotor. The rotor of synchronous motor has dc excitation winding, so it needs to be coupled with excitation power supply to introduce current through the slide ring. The rotor of the asynchronous motor is a short-circuit winding, which generates an electric current through the electromagnetic induction. Asynchronous motor is simple, low cost, easy to install, use and maintenance. It has been widely used. Disadvantages low efficiency, low power factor of power grids. And synchronous motor with high efficiency is the capacitive load, can improve the power factor of power grid. Multi-purpose mining large not ready.
- Q: What is the effect of the ac motor on the connection of direct current
- First, the motor will not turn, the second is to see how much of the direct current you are connected to, and if the voltage is high, the temperature of the motor will rise steeply until it burns. Of course you don't have a problem with a dry battery.
- Q: What are the advantages and disadvantages of synchronous motor and asynchronous motor?
- Asynchronous motor application: motor, its power range from several to tens of thousands of kilowatts, is in the industries of national economy and People's Daily life, the most widely used motor power for a variety of mechanical equipment and household appliances. For example, the machine tool, small and medium rolling steel equipment, fan, pump, light industrial machinery, metallurgy and mining machinery, mostly adopt three-phase Asynchronous Motor (Asynchronous Motor). Electric fans, washing machines, refrigerators, air-conditioners and other household appliances are widely used in single-phase asynchronous motors. Asynchronous motors can also be used as generators for wind farms and small hydroelectric plants.
- Q: Why is it that high speed motors rarely communicate?
- The iron core of the motor will have copper damage, iron loss, increased communication frequency, and increased energy loss.
- Q: The ac motor doesn't have a brush so how does the rotor rotate?
- If you remove the core, you will see something like a coil, usually made of easily conductive metals such as copper or aluminum. Because ac power is a three-phase alternating current of the sine wave, a rotating field is formed on the coils, so there is less of a dc motor.
- Q: How to connect the ac motor to turn and reverse ~!
- A single motor usually has two winding three joints, one of which is a common point, and the other two wires start the capacitance. If the wire is connected to the common point, the zero line is connected to any one point of the capacitor and the motor will turn, and the switch will be turned on the other point of the capacitor and the motor will be turned upside down!
- Q: What is the difference between dc motor and ac motor?
- In theory, dc motor can be used as a generator in the theory of direct current and ac motor
