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: wondering if there is any solution for braking motors other than a vfd braking , heard about dc injection braking any idea on how a dc injection braking would work ? . A dc injection braking for ac motors
- The 'authentic potential' decrease fee quotes would be according to potential ingredient. The section-controlled DCpersistent would have a undesirable potential ingredient at decrease speeds, coming near an very almost appropriate potential ingredient at complete speed. The V*A used interior the motor isn't that plenty diverse. The DC motor demands a magnetizing field to be energized (different than PM automobiles), as does the AC. The AC magnetizing present day is extra stable to make certain, yet is calculated by way of greater end drives, such which you are going to see that the 'loss' or 'overhead' of in simple terms turning the shaft devoid of load.
- Q: I thought it was a short because my ac/heater would blow then the next time it wouldnt but would start up.. now it doesnt blow any air at all. im pretty sure it needs a new blower motor, does anyone know around how much that might cost? im going to call around tomorrow
- sounds intense is it a fur down that unit above your bath or hallway no count if it extremely is you will possibly evaluate changing the full unit out if its in a closet thank you to intense a cost the two way make helpful your evap coil is sparkling or wiped sparkling
- Q: i have a motor that need dc current but i don't have the equipment with dc i have only ac. what is the difference of ac and dc
- AC voltage alternates polarity 60 (50 in Europe) times a second, meaning the AC current changes direction that often. Only AC is good for transformers, and AC motors tend to be more efficient and constant speed. You just need to know what DC voltage you need for the motor. If it's 12 volts, most people will just use a car battery for a source. You can hook batteries in series for higher voltage. You can also buy power supplies that turn AC into different DC voltages.
- Q: I don't understand the benefit, especially in electrical transmission. Furthermore I don't know why AC is better for transmission other than the fact historically speaking, converting DC back to AC was impossible- but as far as I know DC current is better because it uses the entire cross-section of the conductor as opposed to the skin effect that AC causes, so in this day in age isn't DC smarter? For example the huge HVDC line that services parts of California. Or does AC travel further distances? Why is it that AC can be stepped up or down with transformers, but DC can't?I don't know what a rotating magnetic field is why this is good for electric motors, and I don't know why it is helpful for their peak voltages to all be offset.
- Historically, the first power systems were DC only. Voltages could be stepped up (and currents stepped down) using dc motor-generator sets. The invention of AC power let to a much less costly way of changing voltage and current: by using transformers. The California HDVC intertie has the distict advantage of not tying two separate grid systems together synchronously. If one part of a grid starts to fail and triggers a cascading effect that takes down the entire grid, it won't continue through the intertie to effect the other grid.
- Q: i want an ac motor for a small wind mill as an experiment only.no matter if the motor is small.i tried the experiment on a motor from a toy but my friend said those are dc motors.i need answers on following questions:1): where from can i get an ac motor ( preferably from things of daily use / household )?2): is motor in toys AC / DC?3): can DC motors b turn into AC and how?*one who try to answer me in better way explaing (not too much) and suggesting some sites too for its pics can get his answer chosen as best at maximum rating(5 stars).thnaks
- A You can buy a small AC motor from Graiger's Supply or on EBay. B Most toy motors are DC because they are battery powered C No unless you make a special circuit to convert AC to DC power, a DC Motor will not work as an AC Motor
- Q: hi, i am doing my final yea project and i have decided to build a electric can crusher, i have performed some laboratory test and it take around 3000 N force to crush some cans. now i need to choose my E.motor and not sure which one to choose, and also not sure what gear ratio i need for my sprokets.thanks
- Easy man,,,,,,,, just go for a motor which has an power greater than 3000N or you select a low power motor and increase the gear ratio..... come on man do it........
- Q: what are the two types of motors that are for a single phase multi-speed applications?
- 1-fans,split phase 2-blowers,shaded poles
- Q: What kinds of AC motors are divided into?
- The AC motor can be divided into squirrel cage AC asynchronous motor and winding AC asynchronous motor according to the rotor difference
- Q: AC motors have no commutators and are driven by alternating magnetic flux. How can AC motors be controlled to one side, and how to realize positive and negative turns?
- A sinusoidal voltage with a lead of 90 degrees or a phase of 90 degrees after a large capacitor is generatedAnd the original voltage can form a set of voltage difference of 90 degrees phase,.2 group voltage together can control its directionIf it's 90 degrees ahead, it's turning right. Then it will be reversed after 90 degrees
- Q: how can i calculate the no load power and no load current of a ac/dc motor from nameplate data?
- On my experience, no load current of AC motor is about 40 % off nameplate (full load) current sorry for I don not have experience in DC motor
