Q:Calculation method of motor torque
There is a formula for your problem: Electrical power: P = 1.732 * U * cos phi Torque: T = 9549 times P/n; Power torque = 9550 * output power/output speed Torque = 9550 * output power/output speed P = T * n / 9550 The formulas The relationship between motor power, torque and speed Power = force * velocity
Q:How does the three-phase alternator work?
Three, through the bearing, frame and cover the generator stator, rotor connected together, can make the rotor spinning in the stator, the slip ring passed certain excitation current, make the rotor, a rotating magnetic field of the stator coil cutting lines of magnetic force to do exercise, thus induced potential, through terminal lead, in the circuit, the electric current is produced.
Q:How do ac motor maintenance and maintenance?
electrical 1, the winding resistance equilibrium, 2, alternate insulation, 3, the winding is insulated from the earth, 4, is the terminal block loose or not, Whether the running current is normal, 5, what is the temperature rise at run time? Mechanical aspects 1, bearing noise, 2, the bearing temperature rise, The dust of the motor case should be cleaned regularly.
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:Can alternator speed improve power generation?
You say the speed is less than 3,000, the torque of the rotor is not rotating, the motor is taking energy from the grid and keeping it constant, It doesn't provide energy to the grid. Rotor torque, the generator can generate electricity is the fundamental condition, the rotor can rotate, because the rotor torque, such as water can hydraulic generators, wind generators, etc.
Q:Please communicate the motor. It is possible to speed the speed with a governor
Teacher, could you tell me can use electric fan transmission to control, 220 v370w unidirectional and bidirectional motor, is connected to electric fan way can use, thank you very much
Q:How to judge a three-phase ac motor
Three-phase resistance line resistance is measured with meter, first to see if there is resistance, and then to the equilibrium value is decrease (maximum minimum), general corporate control within 1% resistance unbalance degree, resistance unbalance affects a relatively high fever, insulation damage easily.
Q:There is a difference between ac frequency conversion and dc frequency conversion
Ac frequency conversion speed regulation than dc speed regulation is widely used because of ac motor, is not a principle of frequency control of motor speed has the superiority, frequency control of motor speed can only be applied to speed regulation, and to control the torque is unable to be precise, the reason is very simple, dc speed control of the armature and the coupling of the excitation is not, is separate, so to the armature current and exciting current to achieve precise control. And ac speed regulation, armature current and exciting current are coupled, is unable to achieve accurate control, while the current vector control, frequency control of motor speed has also is using the modern control theory, by the vector transformation, the ac motor in the coupling of the armature current and exciting current, thus carries on the control, the principle of dc speed regulating is simulation. But it is difficult to control the dc speed control. Therefore, in mill, paper and so on, the torque demand is very high, dc speed adjustment is also widely used. For speed control only, current frequency conversion speed is the characteristic of realistic dc speed adjustment, because the advantage of ac motor is that dc motors cannot.
Q:Why does ac motor speed control system replace dc motor speed control system?
The PWM control is the control core of the ac speed control system, and the final implementation of any control algorithm is almost done in various PWM controls. Has been put forward and the PWM control scheme of practical application to more than a dozen, articles about PWM control technology in many famous electric power international conference, such as PESC, IECON, EPE has formed at the annual meeting
Q:The ac motor is not positive and negative, so how do you achieve positive and reverse?
Three-phase motor fixed wiring to produce a circular rotating magnetic field, single phase motors through a secondary coil series capacitor formed an elliptic rotating magnetic field, as long as the connection method is fixed, the above two is fixed in the direction of the field Change the wiring method, can change the rotation method of the magnetic field, realize positive and backward turn
