Overview
This series motor is a variable-frequency three-phase asynchronous motor exclusively designed for tower cranes and other similar dewing mechanisms. It is applied to the dewing
mechanisms in very harsh working conditions such as construction site or open pit quarry.
Features
With introduction of spline drive shaft, it has good mechanical bearing capacity;
The motor is a variable-frequency motor featuring a wide range of speed regulation, high efficiency, small starting current, big starting torque and overload ability;
A thermal protection component is buried into the in winding, making motor more safer and reliable;
Excellent dedicated variable-frequency insulation materials are adopted, improving greatly the insulation reliability;
Compact structure, small volume, lightweight, so it can be braked quickly and positioned accurately. It is suitable for frequent starting and braking;
YTRVFW series motor is provided with an eddy current brake on the basis of YTRVF series. It enables more smooth starting and deceleration braking, making the operation
more smooth and accurate
Users’Options:
This series motor is divided into F1 and F2
F1 with airvane brake;will be determined by the
F2 without airvane brake;users when signing the contract but an encoder interface can be reserved
- Q: How to judge the quality of three-phase AC motor?
- How do you measure the Ohm's profile in a multimeter to determine the good or bad of the motor?. First, check for open circuit, U1 to U2, V1 to V2, W1 to W2 two, check insulation U1 to V1.W1, U1, V1, W1 to ground.
- Q: I want to make a Brush-less DC motor that goes 1720 Rotations Per Minute while carrying a 70 kilograms load on it. The motor must be 50mm in diameter and about 15mm in width.How do I go about making that and what kind of specifications must a battery have, to be able to run this for 1-2 hours?Thank you in advance! :)
- your question is unclear, it has no mention of work or energy. you can have motor of that size running at that speed and moving 70kg load if the motion is sufficiently slow, say 1meter per minute. this can easily run on batteries for couple of hours. but if you are looking for a motor to power electric bike for example, you will notice that this is hopelessly undersized. better way is to ask questions in terms of real work, for example pump x volume of water per hour to elevation of y meters or provide power for electric bike where total weight is 90kg, travel speed is 40km/h and expected one charge commute distance is 70km.
- Q: I have a 220v motor stripped from a hair dryer that looks like a DC. How can I differentiate (visually or through tests) a DC motor from a AC / DC (universal) motor?
- The hair dryer motor is universal, ie it will run on AC or DC. The main difference between the two is that the AC motor has laminated field poles and is always a series connected motor. the only disadvantage of running a universal motor on AC is that you will get some sparking at the brushes.
- Q: Hello, I'm thirteen years old, and II took apart this old small vacuum and it's as strong as a dang weed-blower, I cut the cord off and attached it with electrical tape and wire-nuts. And it is not one of the grounded motors either, it has a plastic case over the motor. It has a fan that sucks air from one end, and blows it out of the hole into the bag on the other end, also on the other side of the motor is a shaft possibly this wide: ----- so im wondering if it could be strong enough to move a 150 lb person?If so, how would I power it with batteries? (or even convert the AC motor to DC.)Thanks!
- Don't waste your time. Sure, it might move you a little bit and not fast or far. Remember, the more the load, the higher the current. Stop it spinning with the power on and I guarantee it'll draw a lot more than 12 amps. See if you can find some low voltage DC motors like car engine starter motors or those used on motorized wheelchairs. Why they started rating vacuum cleaners by current draw escapes me as it has little bearing on the suction power.
- Q: is it jus possible by altering d electrical connections
- Oh guy I merely enjoyed jenifers answer - very functional! For the easy reason it incredibly is impossible to truly convert a single area induction motor to be a generator of useable electrical energy ...
- Q: New blower motor on 7900 coleman gas furance will not turn my fan unless i push the fan with my finger to ge?
- I presume the motor is an AC motor. It almost certainly uses a start capacitor to provide the push you are giving it with your finger. The capacitor itself may be bad, but it is even more common to have a bad start contact in the control circuit. The capacitor is only connected long enough to get the rotation going. The first source should help.
- Q: What I want is to generate electricity out from a 2Kw generator alternator and driven by a 800watts AC motor or any AC motor which is much smaller in electricity consumption. I am not thinking of a perpetual machine but to minimize my electric consumption. The AC motor will be connected to the power grid to drive the 2Kw generator alternator.. is this possible? Thanks ahead.
- But you are thinking of a perpetual machine . You attempt would lead to a negative result, where you pay more for the losses.
- Q: Now I will start off with that I have had no issues with this vehicle yet unlike some other Versa owners. Short story is whatever idiot replaced the battery right before I bought it didn't properly tighten the cable onto the terminal. So it popped off. This was easily fixable by repositioning it and tightening it down. Well the bad news is at some point or another when I tried to start with the battery partially connected (I didn't realize this was the case until I tried starting a couple times to no avail) it must have surged and blown something out in the AC electrical area. I checked all fuses, they're good. I looked at the service manual and there appears to be a relay between the switch and the compressor. So I'm hoping its that relay. The options that remain are relay blew, which is quite possible, or the switch or the BCM that controls the switch got surged or blown. Any thoughts? Also I haven't been able to locate the relay yet, do I just need to pull the dash to get to that? Thanks.
- If the AC motor working purchase a can of AC Fluid with hose attached at walmart cost $15 to $20.
- Q: I know they come with different max torques... but can you give me a range of torque for the 120VAC 60HZ motors?
- Horsepower = Torque*Rpm/5252 Many AC motors have a pretty flat torque curve, but not all. You can get an approximate value from: Horsepower*5252/RPM = Torque in foot pounds Example, a 2HP/3600RPM motor would give about 3 foot pounds of torque at 3600RPM. If the motor is rated at 1/2 horsepower and 180RPM, you would get about 14.5 foot pounds of torque You can modify these motors' torque within very wide limits with a gear reduction, increasing or decreasing it.
- Q: ok i have a 95 nissan pickup and my ac went out the other day i can still feel cold coming out the vent the blower motor ant comming on i straight wired it 2 the battery and it works could my resister be bad does the resister have any thing to do wit the ground on the blower motor
- I THINK that it is right behind the blower motor under the dash. Follow the harness from the blower motor and it will lead you right to it. Hope that helps! Matt
