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:Brushless AC motor
The difference between brushless and brush is generally used for DC motors. AC motors are not classified by brush or brush.
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.
Q:Does the AC motor have carbon brushes?
Yes。 Carbon brush for AC motors: carbon brushes can be used in direct current motors or AC commutator motors or slip rings as sliding contacts for introducing current
Q:Types of AC motor speed control and the difference between them
Frequency conversion speed, which is currently the most commonly used control methods, can achieve stepless speed regulation, the semiconductor converter (or circuit) to change the power supply frequency of the motor, the power (frequency =50HZ) change into the required frequency achieve the purpose of speed, or the above formula: =60f/ magnetic pole synchronous AC motor speed. The frequency of "F", the speed will change.
Q:Is the permanent magnet synchronous linear motor AC motor or direct current motor?
Permanent magnet synchronous motor (PMSM) is usually referred to as brushless DC motor with back electromotive force, trapezoidal wave and armature current as square wave. The back electromotive force and armature current are both sine waves, which are called permanent magnet synchronous motors.
Q:Winding of single-phase AC motor?
Depending on the type of motor, the range motor is the same as you say. Asynchronous motors are not like this.
Q:What are the similarities and differences between brushless DC motor and AC brushless motor?
Generally used in Brushless DC generator excitation, AC motor is brushless, there is also a brush, brush motor are generally small motor, because of the need to address the short-circuit current commutation time, so the exchange of brush motor is not too large, think like DC motor, DC motor there are also problems of DC motor reversing, so don't do too much! Brushless DC motor is actually an AC motor, which is usually used in the excitation system of the generator!
Q:The actual power consumed by a three-phase AC motor is equal to line voltage * line current. How do you explain that?
I guess the questioner didn't know the difference between the line voltage, the line current and the phase voltage, the phase current.Line voltage and line current are considered when standing on the power supply side or standing outside the power equipment, while the phase voltage and phase current are considered in the interior of the power equipment. Of a global quantity represented by a physical quantity such as power, the use of line voltage and line current will, of course, be more convenient and direct.
Q:How many kW or more AC Motors should be started with the starter?
In fact, the problem needs to be taken into account in 4 main elements:1, when the motor starts, the voltage on the power distribution bus at all levels meet the normal use requirements of other equipment;2 、 mechanical energy can bear the impact torque when the motor is started at full pressure.3. The structure of the motor itself can withstand the impact of full pressure starting.4 、 does the motor start with special requirements?.
