Q:How do I know whether the motor is a direct current motor or an AC motor?
Look at the nameplate, such as AC 220, V is AC motor, DC 220 V is DC motor!
Q:What's the UVW representative of the motor, please?
Three phase alternating current is a form of transportation of electrical energy, referred to as three-phase electricity. Three phase AC power supply is composed of three alternating current potential with the same frequency, equal amplitude and phase difference of 120 degrees. There are many uses of three-phase alternating current. Most of the AC power equipments in industry, such as motors, adopt three-phase alternating current, which is often referred to as the three-phase four wire system. In daily life, the use of single-phase power supply, also known as lighting electricity. When the lighting power supply, use three-phase electricity one relative to supply electrical equipment, such as household appliances, while the other one is the line of three-phase four wire fourth wire, which is the zero line and the zero line drawn from the neutral point of the three-phase power.
Q:How to change DC motor to AC motor?
DC motor to AC motor, single motor is good to change, as long as the power and speed approximate. The key is to change the control, DC speed control device to be replaced by AC control system, especially if you want to speed, you must install the inverter, the motor also choose AC inverter three-phase asynchronous motor.You mentioned the 2200rpm, I do not know whether the rated speed or actual use speed, DC motor should have rated speed and weak magnetic speed of two gears. If you are 2200rpm rated, about 45 kW AC machine to choose 4 pole motor, 4 pole motor rated speed is 1500rpm (50Hz), need to increase the frequency, we must choose the variable frequency motor, variable frequency motor 50Hz under constant torque, constant power 50~100Hz, should be able to meet the needs of equipment.As for the Japanese motor, which sell, it is difficult to say. Even if you can buy it, it should be sky high. If there are no special requirements, it can be changed into a three-phase asynchronous motor made in china. Should fully meet the electrical requirements.I've done a lot of imported motor localization project, Japan also had many alternative motors, such as MITSUBISHI, Hitachi, Yaskawa and so on, the German motor can use domestic alternatives, not to mention the small Japanese!
Q:Motor PWM how to speed?
PWM speed control principle of AC motor and DC motor speed control principle is different, it is not through frequency modulation to adjust the motor speed, but by adjusting the driving voltage of the pulse width, and the circuit of some energy storage elements, change the delivery to the amplitude of the armature voltage, so as to achieve the purpose of changing the speed of DC motor. Its modulation mode is amplitude modulation.
Q:Common problems of AC motors
Prevention: (1) eliminating the pulsating flux and power harmonics (such as in the inverter output side with AC reactor); (2) motor design, the bearing seat and a base bearing insulation insulation cover, the outer ring of the rolling bearing and the end. 2, why can't the General Motors be used in the plateau area? The altitude has adverse effects on motor temperature rise, motor corona (high voltage motor) and commutation of DC motor. We should pay attention to the following three aspects: (1) the high altitude, the motor temperature rise, the output power is small. But when the temperature drops with the elevation, it is enough to compensate the influence of elevation on the temperature riseWhen the rated output power of the motor can be changed; (2) high voltage motor to take anti corona measures in the plateau; (3) altitude against commutation, be sure to use carbon materials. 3, why should not the motor run light load? When the motor is in light load, it will cause (1) the motor power factor is low; (2) the motor efficiency is low. Will cause waste of equipment and uneconomical operation. (1) the load is too large; (2) lack of phase; (3) the air duct is blocked; (4) the low speed running time is too long; (5) the power supply harmonic is too big.
Q:How can direct current drive AC motors?
Originally 24V battery driven 120W motor, want to use alternating current drive, need a AC/DC power.Buy a AC220V/DC24V 10A (big, expensive, how many, but safe) switching power supply.If you do it yourself, buy a 220V/12V 150-200W transformer, a 10A rectifier bridge, a heat sink, and a few 50V4700uF filter capacitors. Transformer voltage transformer to 12V, rectifier, filter, DC 24V.
Q:Who knows the main difference between DC motor and AC motor, I hope to say a little more simple, thank you
As the name suggests, the direct current motor uses DC as the power supply. AC motors use alternating current as power source.Structurally, the principle of the direct current motor is relatively simple, but the structure is complex, and it is not easy to maintain. The principle of AC motor is complex, but the structure is relatively simple, and it is easier to maintain than the direct current motor.
Q:Is the 380V single-phase AC motor the same as that of the 220V AC motor?
Two of the same pulse magnetic field is formed in time and space, so that a rotating magnetic field produces the air gap between the stator and the rotor, the rotating magnetic field, the induced current in the rotor current, and rotating magnetic field interact to produce electromagnetic torque, the motor rotation.
Q:The difference between DC motor and AC motor in electric stacker
Advantages of DC motors1. DC motor has good starting characteristics and speed characteristics2., the torque of DC motor is relatively large3., maintenance is cheaper.4. DC motor DC relative to the exchange of energy-saving environmental protection.
Q:Why is the AC motor connected to the capacitor?
The capacitor is used for phase separation, to make the current phase two Rao group produced in the nearly 90 of the difference in eve joy to produce a rotating magnetic field. In three-phase electric current, the current between each phase has phase difference itself, do not divide phase. A capacitor induction motor has two windings, that is, the starting winding and the running winding. The two windings are 90 degrees apart in space. At the start of a series of winding capacitor is larger, when the running winding and start winding through the single alternating current, because the capacitor current of the starting winding in time than the current running winding advance angle of 90 degrees, the first to reach the maximum. Two of the same pulse magnetic field is formed in time and space, so that a rotating magnetic field produces the air gap between the stator and the rotor, the rotating magnetic field, the induced current in the rotor current, and rotating magnetic field interact to produce electromagnetic torque, the motor rotation.
