This serial products consist of wound rotor three-phase asynchronous motor,centrifugal fan and break-type electromagnetic brake. The
rmistors are embeded in stator winding
The motor brake is connected with shaft by spline. It is equipped with manual release device,which relieves the brake in the case of power
failure, so that it is easy to install and commission the motor or set down the heavy objects in the condition of failure
This type motor rotors are specially designed. Referencing the French technology, the shaft ends are closed by new-type hermetically
sealed construction, and the vriginative electromagnetic brake extends the life of motor airtight. When throwback is activated, the mechanical
and current impacts are smail,and also the vabration and noise are small. The comprehensive performance of this serial motors is greatly
enhanced
This type motors can be used to substitute those imported from France.
- Q:Criterion of selection between a AC and a DC motor advantages and the disadvantages of them?
- Since you are asking for the criterion of selection, here it is.. AC motors have two coils: an outer coil to produce magnetic field, and an inner coil to produce counter electric field. DC motors have an outer magnet, and an inner electric field. DC motors need DC voltage supply, and since all of the household supply is AC conversion is needed (thus making DC more inefficient, although the loss is minor) AC motors give better torque than similar DC motors. Since AC motors have two ciols, the magnetic field between the two colis can be adjusted to give maximum efficiency or power (something that DC motors cannot do)
- Q:why ac superconducting motors are common and not dc?
- Its so simple AC is cheap.
- Q:the difference in construction, what does 1 of them has that the other does not and what does this part adds to it and thanks
- what does 1 of them has that the other does not? usually a simple dc motor has a commutator and an ac motor has slip rings.
- Q:Which motor has a great torque when the motor is under DC at the same power?
- If the DC / AC motors operate under the rated 800W output power, there is no doubt that, as long as their speed is the same, the output torque is the same, which is a static consideration.
- Q:I have a large shop fan that is belt powered by an electric motor. Here a while back the fan stopped running and would just hum when it had power. If you pushed the fan blades it would start running. That told me that the likely suspect was the starter capacitor. Today I went to Grainger and picked up a replacement. Unfortunately they did not have a direct replacement but verified that the one they had would work. Came home.. hooked it up.. and it still will not start on its own. Although I did not mark down how it was connected months ago when I took it apart, it is only two wires and I could tell on the original piece where they were connected. Am I missing something here? Is there more to replacing a capacitor than just wiring a new one up? Or is there something else wrong. Thanks in advance!
- what is the voltage of the motor? does the fan turn freely without the belt? does the motor shaft turn freely? if there is a bind in the motor then that may be what is preventing it from gaining momentum. try to run the motor without the belt. you may just need a new motor. EDIT: if the motor runs freely when disconnected than make sure nothing is binding up the fan... try some WD40 until the fan spins effortlessly... if that doesn't work than you probably need a new motor. The commutators, brushes and springs the others are talking about are mostly found on DC motors. you have an AC motor. your motor is probably a dual-voltage... i.e can be wired for 120V or 240V... make sure it is wired correctly by looking at the motor name plate/wiring diagram.
- Q:anybody could give me some answers...what is the difference between ac brushless generator and non-brushless generator?? how about PMG generator??how to improve torque in dc motor??please anybody..??
- which windings are available on ac generator stator how do u come up with a neutral cable during rewinding
- Q:The direction of alternating current keeps changing. How about the direction of AC motor?
- There are many ways to generate rotating magnetic field, such as three-phase winding method, single-phase phase-shifting method, short-circuit loop method, pulse commutation method, and so on.
- Q:I have a window unit AC. Lately, even when I turn it completely off, the motor runs sporadically. It does not blow air when it does this. It didn't do this until the past few weeks (I've had it several years). It continues to work well other than this.. ols well and everything.
- if its real old it could be the switch is shorting out. try to turn it off and wiggle the switch to see if it runs. Or if it is running try to wiggle the switch to see if it shuts off. Another possible problem could be that the outlet is wired backward and the unit is hot all the time. U would need a outlet tester to find that out or a Volt meter.
- Q:What is the neutral point of an alternating current motor? How to determine whether the neutral point leads to?
- There are mainly two kinds of motor connection, star connection and angle connection two kinds. - star connection is 3 at the end of the three-phase coil motor connected together as a common, common end is neutral.Angle connection -- is to each phase of the three-phase motor through the coil ends are orderly connected with the connection. ?????Three phase winding motor is completely into the end cover is connected, the end cover has six heads, three heads below together, the above three heads respectively leads to the three line is the star connection; the upper and lower two head vertical connection, respectively leads to the three line is connected with the triangle.
- Q:Increasing the number of wire turnsDescreasing the strenght of the fixed side magnetsMaking more splits in the commutatorChanging to a power supply with more electical output.Help please!
- Increasing the number of wire turns but you can't do that for an existing motor.
