Q:The difference between a variable frequency motor and an ordinary AC motor
Variable frequency motor in the speed range of speed can be arbitrary, and the motor will not be damaged, the most general domestic general motors can only run on AC380V/50HZ under the condition of ordinary motor can reduce the frequency or frequency range, but can not be too large, otherwise the motor will heat and even burn.
Q:What are the advantages and disadvantages of AC and DC motors?
AC motor without carbon brush and commutator, maintenance free, strong and wide application, but the characteristics to achieve performance equivalent to DC motor to be used to achieve complex control technology. AC motor is divided into two categories: asynchronous motor and synchronous motor. Asynchronous motor is divided into single-phase asynchronous motor, two-phase asynchronous motor and three-phase asynchronous motor according to the number of stator phases. The three-phase asynchronous motor is simple in structure, reliable in operation and low in cost.
Q:Panasonic servo motor A4 series, AC synchronous motor or AC asynchronous motor?
The servo motor can make the control speed and position accuracy very accurate, and the voltage signal can be converted into torque and speed to drive the control object. The servo motor rotor speed control by the input signal, and can respond quickly, in the automatic control system, used as actuators, and electromechanical time constant, high linearity, initiating voltage characteristics, to convert signals received from the motor shaft angular displacement or angular velocity output. Divided into DC and AC servo motor two major categories, the main feature is that when the signal voltage is zero, no rotation phenomenon, the speed increases with the torque and uniform decline.
Q:How can a DC motor be changed into a three-phase AC motor with good performance?
Selection of asynchronous motor, power 60kW, voltage 400V, speed of only 960 RPM selectable (6 pole), if the speed is not enough to add speed (AC motor only 1500, 1000 (960), 750, 500 and several speed; if optional) must be 1000, as long as the election with step motor, just the price is too expensive.If the power supply capacity is not enough, without speed regulation, you need to calculate the starting capacity, select the starting mode and motor.The starting modes of squirrel cage asynchronous motor include direct start and star triangle startingThe above is cheaperThe starting modes of winding asynchronous motors are resistance start and frequency sensitive variable resistance starting
Q:What is the difference between stepping motor and servo motor and three-phase asynchronous motor? What are the advantages of their differences?
Servo motor servo motor principle: also known as the executive motor, DC and AC servo motor is divided into two categories, servo motor rotor is permanent magnet drive control of the U/V/W three-phase power electromagnetic fields, the rotation of the rotor in the magnetic field, at the same time with the motor encoder feedback signal to the drive, the drive according to the feedback value compared with the target value, the rotor rotation angle adjustment. The accuracy of the servo motor is determined by the accuracy of the encoder (line number).Advantages: as servo motor with motor encoder to form an internal closed loop, the control accuracy is very high, so that it can operate normally at high speed. The drive can communicate directly with the host computer.Disadvantages: high price, long supply cycle of imported goods, high maintenance costs.
Q:Why is an AC motor more popular than a direct current motor? System description, thank you.
Also in accordance with the phase asynchronous AC generator rotation, (here is asynchronous: rotating magnetic field of asynchronous AC motor and AC Alternating Current AC motor drives the rotating magnetic field rotation, phase difference, so that is asynchronous).
Q:Why is DC motor wider than AC motor? High speed regulation accuracy? How do you know?
The speed regulation of DC motor usually depends on changing the voltage at the two ends of the armature. The speed and voltage are basically linear, so the speed regulation accuracy is high. However, due to the brush limit, the DC power is generally not largeThe speed change of an AC motor depends on changing the pole number or changing the frequency, while the mechanical characteristic is related to the rotor resistance, armature current and so on. The ancient and lower precision, to achieve servo control should be introduced into the closed loop control system.
Q:How to make the AC motor stop rotating rapidly?
A, electromagnetic brake.Two, use YEJ motor with brake itself, it also and ordinary Y series three motor mounting dimensions are exactly the same, but with a little bit length.
Q:How the AC motor with DC power transfer
Different manufacturers use different motors for fans.If you are using a series or shunt motor, DC or AC or.If you are using an asynchronous motor, and there is no buck, it will burn, and will not brake.
Q:Why don't AC motors use commutators?
The principle of reading a book, the commutator is used to make the motor current is DC, and if you say that the generator has a commutator, is not ac?
