Q:How to change AC motor to DC motor?
Generally speaking, the motor is AC, and the phase change of the high-voltage DC is too sudden, which is easy to damage the motor. Batteries (electric cars) use dc.A direct current motor refers to an electric motor that uses a direct current supply (e.g., dry cells, batteries, etc.); an alternating current motor is an electric motor that uses a power supply, such as a home circuit, an alternator, etc..
Q:Which price is higher, AC motor or direct current motor? Which one has a longer service life?
Exactly, if it is of the same size, should be AC motor, low price, long service life, AC motor makes the rotor rotating by electromagnetic induction, relative power, and internal heat production is less than that of dc;
Q:The working principle of AC motor!
At present, there are two kinds of AC motors commonly used: 1 and three-phase asynchronous motors. 2 、 single-phase AC motor. The first type is widely used in industry, while the second is used in civil electric appliances.
Q:What is the neutral point of an alternating current motor? How to determine whether the neutral point leads to?
The AC motor only meets the three-phase fire line, the three-phase is balanced, the neutral point does not connect the zero line, also does not have the ground.
Q:Does the AC motor have carbon brushes?
Its electrical conductivity, thermal conductivity and lubrication are good, and have a certain mechanical strength and reversing spark instinct. Almost all motors use carbon brush, which is an important component of the motor.
Q:When the AC motor is burnt out, is the stator burnt out or the rotor? What about DC motors?
It is a mechanical device used to realize the conversion of mechanical energy and alternating current energy. AC motor has become the most common motor because of the great development of AC power system. Compared to the AC motor and DC motor, because there is no commutator (see DC motor commutation), therefore has the advantages of simple structure, convenient manufacture, relatively strong, easy to make high speed motor, high voltage, high current, large capacity. The coverage of AC motor power greatly, from a few watts to several 101000 watts, even millions of kilowatts.
Q:Working principle of AC motor
About two copper rings function: two brush corresponding two copper rings with the current energy source is constantly being sent through the coil. The benefits of this design is: to avoid the two power line of the Chan around the problem, because the coil is on the turn, with two wires to the coil power supply then, two power line will be around the current in the coil of Chan is due to alternating current, current is equal to zero, but this time with the current time is too short than up, not to mention the coil quality, with inertia, due to inertia coil will not be stopped. The AC motor is based on alternating current the characteristics of rotating magnetic field generated in the stator windings, and the rotor coil magnetic line cutting motion, the rotor coil generates induction current, magnetic field induced current induced magnetic field of the stator and the rotor to make the opposite rotation force Moment.
Q:Why is an AC motor more popular than a direct current motor? System description, thank you.
When it comes to AC motor, said first alternating current, alternating current is often used in our daily life, low price, wide use, AC Alternating Current AC motor can adapt to any electrical equipment, is no exception, the reason is the three-phase alternating current of each phase is 120 degrees, 360 degrees, this is just a three-phase AC motor is welcome to good, so the AC motor will be popularized
Q:Winding of single-phase AC motor?
Depending on the type of motor, the range motor is the same as you say. Asynchronous motors are not like this.
Q:The difference between induction motor and induction motor
. a three-phase induction motor is an induction motor, the induction current definition: formed by the rotating magnetic field of stator winding and rotor winding of the magnetic field from the interaction of electromagnetic torque of AC motor drive rotor rotation.
