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: so where can i get a motor that is 117 ph. power using dc current and another motor with the same 117ph. but using AC.of 220v just like thy use in Philippines china and so on that can handle 220v to 230v like in Philippines for example so for the DC Motor i need same 117 hp.
- You have described the motor as 117ph and 117hp. You also want 220V AC and a DC one with the same whatever 117ph is.. The motor pictured is a gear motor and has a power of 40W. If you get your specifications sorted out you will be able to find it yourself. Voltage (230V AC, but DC is what voltage?) Frequency (50Hz or 60 Hz). Phases (1 or 3 for AC). For this low power I expect 1 phase. Mechanical power (in watts or horsepower) RPM (revolutions per minute = speed) Gears, axial and radial torque, gear ratio. Look these terms up for an explanation. If you want speed control it is best to search for a 3 phase gear motor and use a VFD (variable frequency drive), which can run the motor from single phase for smaller motors. The motor and VFD should match. I recommend you find a local sales office for electrical equipment. For a DC motor it will depend on the voltage and mechanical power level, but these usually use some sort of PWM controller. Once again the motor and speed controller should match. These will not be readily available except in smaller sizes.
- Q: How is the speed of an AC motor varied? How is the speed of a DC motor varied?
- hi. AC automobiles are designed and equipped otherwise than DC automobiles. AC automobiles take great element with regard to the 60 hertz clock of a ability line (or 50Hz in different countries) - this suggests the flexibility line differences stages 60 circumstances a 2d - to rotate, on an identical time as DC automobiles are designed with the voltage point utilized. you could administration them the two, yet with diverse ability. the least complicated to regulate is the DC motor (replace the potential (the voltage) and it turns slower or quicker.
- Q: Just replaced the outside condenser units fan motor and it turns the opposite direction than the old one. Wires are correct. Switched the leads on the running capacitor and it didn't help. Any suggestions??
- turn it off switch the yellow and orange that will change your rotation1 yellow to 1 orange as long as its a reversable motor
- Q: What does permanent magnet brushless motor and brushless DC motor mean?
- Permanent magnet brushless motor is usually divided into permanent magnet AC brushless motor and permanent magnet brushless DC motor. Permanent magnet brushless AC motor usually refers to AC synchronous motor. The permanent magnet brushless DC motor can be divided into two kinds of sinusoidal permanent magnet synchronous motor and brushless DC motor.
- Q: Why are brakes on AC motors normally DC? Is it because they use an elctromagnet and maybe they work better on DC?
- The best advise i can offer you is to to check in the electronics mart then if that fails contact the manufacture...
- Q: I have everything, just need to know how to do this. I have a sports car shell so this is really from scratch. I also have prius batteries. Can use some help
- DC motors are easier to use for speed controls and power braking.Better get a DC motor and you won`t have to use an AC inverter.Example electric trams are DC motor operated.
- Q: related to electric goodshow much is thge consuption of 1/4 hp motor
- Assuming you mean amp draw for consumption, there are lots of small differences that vary motor current on a motor to motor basis. The best way is to look at the motor. Look for FLA (full load amps) on the name plate. If you don't have the motor on hand, typical 1/4 Hp motors will pull around 5A at 120VAC and 2.5A at 240VAC single phase. Your mileage will vary depending on manufacturer.
- Q: I've replaced a blower motor in my home AC with a similar motor. It's the same 1075 rpm, but 1/2 hp instead of 3/4 hp (as the old one had). How will it affect my AC performance? Does this power rating matter? It seems that if it's the same squirrel cage and the same RPM,the air flow should be the same.Thank you.
- Yes, it does matter. The horse power rating has to do with the motors ability to turn and maintain a constant RPM under a given load. The manufacturer seems to think that a 3/4 horse power is needed to turn THAT fan. You can use it, but the turning RPM may be less than you need and the life of the motor will be greatly reduced. If it were me, I would use it, but order a 3/4 HP motor ASAP and replace it.
- Q: Do you know of any manufactures of High On/Off Cycle Motors, with a web site.
- So you've got a lot of 480-vac machines cycling every minute and you're wondering if you can get a motor that cycles every 30 seconds? Sure. It is just part of the specs. There's a much higher amperage on start up and all of your machines do that frequently, so they must dissipate heat faster than some consumer grade product or anything not spec'd for frequent cycling. They have to have larger fins, cooling fans, or the vendor just derates some larger framed motor. Sure sounds like your vendor screwed up and is trying to cover his *** after the fact. How could he possibly think you'd want to be surprised by the delivery of a different motor? Sure, call out an alternative in the BID process. But DELIVER what was ordered, unless you've got an approved change order. The lack of reversibility sounds like yet another deviation from specifications and one that is very obviously less flexible, less desireable and non-compliant with the purchase order.
- Q: I want your answer
- A synchronous motor is an AC motor that runs at a speed fixed to a fraction of the power supply frequency, and an asynchronous motor is an AC motor, usually an induction motor, whose speed slows with increasing torque to slightly less than synchronous speed. An asynchronous motor requires slip - relative movement between the magnetic field (generated by the stator) and a winding set (the rotor) to induce current in the rotor by mutual inductance. The most ubiquitous example of asynchronous motors is the common AC induction motor which must slip to generate torque. In the synchronous types, induction (or slip) is not a requisite for magnetic field or current production (e.g. permanent magnet motors, synchronous brush-less wound-rotor doubly fed electric machine).
