- Q: What is the electrical Angle in the motor? What does it have to do with mechanical angles
- Commonly used three-phase brushless dc motor, there are generally three position sensor, the output waveform has two kinds: one kind is phase difference Angle 60 ° electrical, the other is a phase difference of 120 ° Angle. 1 on the poles, for example, phase difference of 120 ° electrical point of view, three position sensor space interval is 120 ° mechanical Angle; 2 on the poles, phase difference is 60 ° electrical point of view, the three position sensor space interval of 30 ° mechanical point of view.
- Q: Single phase single capacitance ac motor three wires wrong
- Two of the three wires are connected to the capacitor, the other is connected to the power supply, and the motor can be operated by a single connection on the two capacitors. When another power source is replaced with a capacitor, the motor will reverse.
- Q: Single phase ac motor voltage speed, voltage torque relation
- Electrical power: P = 1.732 * U * cos phi Torque: T = 9549 times P/n; Motor speed: n = 60f/p, p is the logarithm of the motor. Note: when the frequency reaches 50Hz, the motor is rated at the rated power and the frequency is increased, the power of the motor will not be increased, and the rating will be maintained. When the motor torque is below 50Hz, it is proportional to the frequency. When the frequency f reaches 50Hz, the motor reaches the maximum output power, which is the rated power; If the frequency f in 50 hz will continue to increase, the output torque is inversely proportional to the frequency change, because its output power is so big, you need to continue to increase the frequency f, then set into the calculation formula of the above analysis, the torque is obviously decreased. Speed and frequency is the same, because the power supply voltage unchanged, the frequency of change as a result of direct reaction speed change, compared to the same frequency increases, the speed increase, it decreases another also decreases. Let's look at these formulas for voltage analysis. The stator voltage of the machine: U = E + I * R (I for current, R for electronic resistance, E for inductive potential); E = k * f * X (k: constant, f: frequency, X: flux);
- Q: What is the ac motor made up of?
- The modern car is widely used in air-conditioning units, electric jet engines, electric control doors and Windows, electric adjustable seats, etc. The more advanced the car, the more power it USES. Today's mid-premium car generators are typically about 1 kilowatt. With the increase of automation and comfort, the use of electricity should be increased, but the installation space of cars is limited, and it is impossible to increase the power by increasing volume. As a result, engineers are working on cooling and installing positions. For example, install the generator on the top of the engine and try to stay away from the hot zone. The rear end of the generator is fitted with fan blades to enhance the cooling effect. BMW recently tried to improve the cooling effect of the generator by trying to cool it with water. The starter is made up of motors, actuators, and manipulators. Special start the engine, it needs strong torque, so want to through the flow of electricity is very big, hundreds of ampere, this feature determines it is different from the generator. For example, using dc series motor, the rotor and stator parts are made of coarsely rectangular copper wire. Driving mechanism adopt reduction gear structure; The operator USES electromagnetic magnetic absorption.
- Q: Increase the load on the motor, but not overload. Is the opportunity slow down?
- No matter the dc ac motor, the motor is in the stable zone of the mechanical characteristic curve, but it will only slow down a little bit, but it will be stable.
- Q: The type of speed adjustment of ac motor and the difference between them
- There are three types of ac motor speeds common in industry. 1, the slip motor speed -- -- -- -- -- - on the motor output shaft is equipped with a pair of electromagnetic coupling, speed tests to adjust the magnetic field of the coupling with a set of speed. (not very much now, the disadvantage is inefficiency, the advantage is that it can be adjusted without speed.)
- Q: Why does ac power connect capacitor
- Single-phase motors mostly use capacitance. When single-phase electric current flows through the motor does not produce a rotating magnetic field, need to take the capacitor is used to split phase, the purpose is to make two winding of the current produce nearly 90 ゜ phase difference, in order to produce a rotating magnetic field. The capacitor induction motor has two winding, namely the starting winding and the running winding. The two windings vary by 90 degrees in space. String on the startup winding capacity of a large capacitor, when running and start the windings by single phase alternating current (ac), because of capacitor in the startup winding current on time than the running winding current advance Angle of 90 degrees, to reach the maximum value. In time and space form two of the same pulse magnetic field, in the air gap between the stator and the rotor creates a rotating magnetic field, under the effect of rotating magnetic field, the induced current in the motor rotor, current and rotating magnetic field interact to produce electromagnetic torque, motor rotation.
- Q: Three-phase ac motor star row and delta connection?
- Three-phase squirrel-cage asynchronous motor adopts - delta Y step-down starting advantage: Y connection of the stator winding, the starting voltage for direct using delta connection, a third of the 1/3 of the starting current to delta connection, thus features good starting current, the circuit is simple, less investment. The drawback is that the torque is reduced to a third of the triangular method, and the torque characteristics are poor. So the line is suitable for light or no-load start. In addition, note that the consistency of the rotation direction should be noted when the y-delta joins
- Q: Ac asynchronous generator principle
- Asynchronous generator rotor is higher than the synchronous speed, the stator magnetic field will be of induction coil cutting, voltage and current, if the power grid, the grid frequency control are the synchronous speed. If it is not incorporated into the grid, its synchronous speed will be determined by the combination of the generator's speed and load.
- Q: What will be the result of the power supply to ac motor after the rectifier (not filtering)?
- The ac motor will not be able to transfer the pulse direct current, the light is hot.
