- Q: Is there a sensor in the electric forklift motor? If there is a failure, can the car still walk?
- Electric forklift truck technology has experienced from ac to dc, and returned to the change of communication, the earliest communication technology because of restricted by technology and electronic parts so no, later is popular, dc technology with ac motor, ac electric control, the development of the contactor gradually eliminate dc technology. The dc motor has a carbon brush, which is time-consuming and time-consuming to maintain, and because of the technical constraints, it is often the phenomenon of burning the electrical parts. And the communication technology has greatly improved the service life of the parts of the forklift truck, and the motor has no brush motor
- Q: Why do elevator door motors use dc instead of ac?
- Because the dc voltage is more stable.Dc voltage reliability and stability are high.
- Q: How does the three-phase ac motor achieve constant power or constant torque output
- Is generally frequency converter to realize, in the power supply of power frequency 50 hz, motor with frequency converter to belt, the inverter output below 50 hz, the motor is constant torque output, but in the inverter output above 50 hz, the motor is constant power output
- Q: The rated speed of ac motor
- The rotation principle of the three-phase asynchronous motor Three-phase asynchronous motor to spin the prerequisite is to have a rotating magnetic field, three-phase asynchronous motor stator winding is used to produce a rotating magnetic field. We know that, but the phase of phase to phase voltage is in phase difference of 120 degrees, three of the three-phase asynchronous motor stator winding on the spatial orientation also sent 120 degrees, so, when during a stator winding into the three-phase power supply, the stator windings creates a rotating magnetic field, current every change is a cycle, a rotating magnetic field in a week, i.e., the change of the rotation of the rotating magnetic field and electric current is synchronized. The rotational speed of the rotating field is: n = 60f/P, f is the power frequency, P is the magnetic pole of the magnetic field, and the unit of n is: revolutions per minute. According to this formula, the speed of the motor is related to the number of poles and the frequency of the power supply. In general, the actual rotational speed of the motor lags the rotation of the magnetic field. For this we call the three-phase motor as the asynchronous motor.
- Q: Electric curtain choice dc motor or ac motor?
- Ac motor cheap and long service life (up to only five years), but only for a hotel, office buildings and other projects, a lot of people think the products have passed 3 C certification, not a security issue, if not these products manufacturers of professional personnel to install, can pose a safety hazard, because they don't understand the internal structure of electric curtain motor, such things don't happen again.
- Q: What is the difference between the excitation winding of ac motor and the armature winding?
- Motor learning definition "armature" as the "main power circuit", as long as you think about the power of the stator loop or rotor circuit of large power, the big is the armature. The power is the voltage X current. Only the synchronous generator and the synchronous motor have excitation winding and armature winding. The general ac asynchronous motor is not excitation winding. Squirrel-cage asynchronous motor points and winding type two kinds big, the same stator winding structure, the squirrel-cage rotor cage bar, wound rotor rotor coil is an external device (can change the rotor impedance to realize variable speed). The "armature winding" is the "main power circuit" of the motor. Which power of the rotor and stator coil is "armature", needless to say, most stator coils are "armature winding".
- Q: Can two phase ac motor not be able to install governor?
- In practice, the ac motor is always associated with the production machine, forming the power drag system. Different production machinery requirements at different speeds, even though the same under different operating conditions, production machinery also need different speed, so need to drag system the speed of adjustment, the ac motor speed control. Ac motor, especially cage induction motor, with no mechanical reversing device, simple structure, reliable operation, easy maintenance, low cost, and good energy-saving effect, in such aspects as stand-alone capacity and speed limits are higher than dc motor; Especially in the case of dust and explosive hazards, ac motors are more applicable. But the speed regulation performance of ac motor is not as good as the dc motor. For a long period of time, the ac motor can only operate at constant speed. The problem of speed adjustment of ac motor has been the focus and research of electric drag workers. In the 1930s, many scholars proposed various speed regulating system to improve the speed regulating performance of ac motor.
- Q: How does the brush motor control the positive and backward rotation?
- With the dc motor and ac motor, dc motor can change the polarity of the input power supply and change the rotation direction of the motor. The ac motor can change the rotation direction of the machine by adjusting the two wires of the carbon brush.
- Q: Is permanent magnet synchronous linear motor is ac motor or dc motor?
- Permanent magnet motor, general is small dc motor, and ac motor, generally do not have dc small, the excitation that USES is line excitation also. It's not permanent magnetism. Like some razor, small motor is permanent magnet dc motor, some dc output of the generator, is also a permanent magnet, some also dc generator output, but it was all in after a dc generator output, and is not directly the output direct current.
- Q: Dc motor and ac motor, which is better for mechanical hands?
- DC power amplification, but not to control steering servo DC signal, and is adjustable wide pulse signal, so as to obtain the high precision control. Pure DC signal can also control the rudder Angle, but control may be too long, for example, if you need to 31 degrees from left 30 degrees to the left, with DC signal may need to 1 second, and using PWM pulse may need only 0.1 seconds
