Q:Soybean milk machine ac motor or dc motor
Soybean milk machine motor and other small appliances chooses to supply the power source is communication, but into the motor coil is used through commutator after dc, the dc motor also includes excitation coil. It is not economical and unrealistic to use dc motors directly under current power systems. "Ac motor" is a machine used to realize mechanical energy and exchange electrical energy. Ac motor has become the most commonly used electric motor due to the huge development of ac power system. Compared to the ac motor and dc motor, with no commutator (see dc motor commutator), so the simple structure, easy fabrication, quite strong, easy to make a high speed, high voltage, high current, the large capacity motor. Ac motor power covers a wide range, ranging from a few watts to several hundred thousand kilowatts and even a million kilowatts. In the early 1980s, the largest turbine generator was 1.5 million kilowatts. [1-2] ac motor was invented by the American Serbian scientist nikola tesla.
Q:Calculation method of motor torque
The characteristic of dc motor is that the lower the speed, the greater the torque, and the variable frequency motor is constant torque at lower rated speed, so it cannot be equivalent. Only by analyzing the operating condition of the system, the condition of the constraint can be made correctly.
Q:If you measure the temperature of the motor cover more than the environment temperature above 25 degrees, suggests that the rise of temperature of the motor is beyond the normal range, general motor temperature rise should be below 20 degrees. The general motor coil is made of enameled wire, and the enamelled wire will be flaked out by temperature over 150 degrees, causing the coil to short-circuit. But generally does not exceed 95 ℃.
The insulation grade of an electric motor refers to the degree of heat resistance of the insulating material used in the motor, which is A, E, B, F, and H. A temperature rise is the limit of the temperature of the motor relative to the ambient temperature. Temperature rise is refers to the motor in the rated operating condition, the temperature of the stator winding of environment temperature is higher than that of numerical (ambient temperature of 35 ℃ or below 40 ℃, if the brand of the concrete numerical value, not for 40 ℃) temperature rating of the insulation class A E B F class H maximum allowable temperature (105 ℃), 120, 130, 155, 180 winding temperature rise limit (K) 60, 75, 80, 100, 125 performance reference temperature (80 ℃), 95, 100, 120, 145 in generators and other electrical equipment, insulation materials is the most weak link. Insulating materials are particularly vulnerable to high temperatures and accelerate aging and damage.
Q:Ac servo motor can be divided into synchronous ac servo motor and induction ac servo motor
The drip ac servo motor can be divided into synchronous ac servo motor and asynchronous ac servo motor Asynchronous ac servo motor is what you call induction ac servo motor
Q:Why does a single motor have a series of capacitors
As we all know, the rotation of the ac motor on electric current produced by a rotating magnetic field, and single-phase motor is different from the three-phase motor, three-phase motor through 120 degrees is the difference in phase and three phase current, can produce a rotating magnetic field; And single phase motors through the single phase current does not produce a rotating magnetic field, need to take some methods to make it produce a rotating magnetic field, using capacitance is one method, which is the most common method, capacitance is used to split phase, the purpose is to make two spare set of the current produce nearly 90 ゜ phase difference, in order to produce a rotating magnetic field.
Q:How to control the start-stop of 220V ac motor with a single chip?
The digital output of the single chip is high and low, which can be used to control the power or power failure of the cable, so as to make the contact of the relay contact or break. The relay parameters include two main points. Line pack voltage, contact voltage current. Also consider the volume and connection mode. 3, line pack voltage, 5V, 9V, 12V, etc. Let the coil be connected to the voltage. The simple solution is to control NPN directly. Vcbo, the CEO of Vcbo generally meets the requirements. The current amplification and dissipation power are sufficient to satisfy the line package drivers. The contact point is usually dc voltage current, ac voltage current each set of parameters. According to the actual power failure flow choice. 5, with the line package voltage parameter, the contact parameter, the simple judgement of the volume size, select the relay of the good brand, such as omron. Wish you success!
Q:Single phase capacitor ac motor speed regulation why does not have corresponding frequency converter
It is suitable for low load, such as fan, blower, exhaust fan, etc. The voltage is reduced, the strength of the winding is reduced, the rate of change increases, and the speed decreases. If the load is larger, the voltage is reduced by the lower voltage, and the power of the motor is reduced, and the coil is likely to be overcharged and the coil is hot and burnt. A fan without a speed governor is more than one way of controlling silicon.
Q:How the ac motor works
The principle of ac motors: the coils spin in the magnetic field. Do you know the principle of direct current electromotor? Dc motor commutator is used to automatically change the direction of the current in the coil, so that the coil stress direction is consistent and continuous rotation. So as long as the guarantee coil stress direction is consistent, continuous rotary motor will be. Ac motor is the application of this.
Q:What is the regulation method of ac motor? What are the different features
Friend, one, change the logarithmic speed control method: change the red way of the stator winding to change the stator pole of the cage motor to achieve the speed adjustment. Two, frequency control method: changing the frequency of the motor stator power by using the frequency converter, changing the speed control method of the synchronous speed. Three, cascade speed regulation method: cascade speed regulation refers to the wound rotor motor rotor loop series adjustable the additional potential to change the slip of the motor, to achieve the purpose of speed control. Most of the slip power is absorbed by series of additional potential to recycle produce additional device, the absorption of returning the slip power grid or conversion of energy use. According to the slip power utilization way, cascade speed regulation can be divided into motor cascade speed regulation, mechanical cascade speed regulation and thyristor cascade speed regulation form, adopts thyristor cascade speed regulation. Four, wound rotor motor rotor series resistance speed control methods: line type asynchronous motor rotor string into the additional resistance, make the slip of the motor, motor under low speed running.
Q:What is the difference between dc brushless motor and dc brushmotor?
A longer life. A short lifespan. A loud noise. A small noise. The electric car now USES almost all brushless motors
