Overview
YZPE2 variable-frequency three-phase asynchronous motor for lifting and metallurgy purposes is developed according to the characteristics of the
available tower crane, based on almost 10 years of experience in R&D of primary hoisting motor brake for the tower crane and metallurgy variable-frequency
motor. Lt is mainly used as a lifting mechanism of the tower crane, and also a trolley mechanism of heavy-duty crane
Features
A variable一frequency special motor is equipped, available with a wide range offrequency conversion, small starting current and big starting torque;
A thermal protection component is buried into the winding, and can be wired into motor temperature control& protection system, making the motor
operation more secure and reliable;
Strengthened inter-turn insulation is adopted in the stator winding, so the insulation reliability is higher;
Equipped with axial一flow fan or centrifugal fan, with good cooling effect and lower motor temperature rise;
Special bearing is adopted for variable一frequency motor, so it's more suitable for variable一frequency operating environment;
The rotating shaft is subject to alloy steel heat treatment, showing better mechanical strength;
The brake (fitted with special manual release device) is a de-energized brake type (national utility model patent, Patent No. ZL201120188124.9), with big
braking torque and short response time
Users’Options:
A rotary encoder can be set at the end ofthe motor as per the user demands, so a speed closed-loop control system isformed to make adjustment more reliable and accurate. The encoder model isconfirmed by the users when signing the contract
- Q:How to make the AC motor stop rotating rapidly?
- Electromagnetic brake, load and DC braking or braking circuit of DC power consumption
- Q:I am connecting a 400 watt electric motor to my bike, along with a inverter since the motor runs of ac power. I am trying to find someway of adding a new and separate gear onto my bike without damaging the bike, or welding anything, and making the device possibly removable. I am hoping to run a chain from the motor to the gear I added on.
- Note that most electric motors can't be run at low speeds for long periods, or they'll overheat and wear out! Therefore the rated operating speed of your motor needs to equal the average rotation speed of your wheels at cruising speed, multiplied by the gear ratio. You will need to do some calculations. Your cruising speed should be around 15-20 miles per hour. That's around 20-30 feet per second. That's 240-360 inches per second.
- Q:Is it ok to leave the heater in the quot;on positionquot; even after I turn my car off? Will it cause any damage to the blower motor, if every time I turn on my car; the heater turns on automatically because it's in the quot;on positionquot;?
- Yes, it is not getting any power while the car is off.
- Q:It is possible AC motor run on DC supply.What can i do to run a AC motor on DC Supply
- Unless it is a universal motor, NO. Generally, you would need an inverter.
- Q:Sorry that no one could read my mind in answering this question last time. The answers were not to the point. quot;To maintain same power at lesser voltage you need more currentquot;. Well does the motor know what power it has to deliver? Isnt the power delivered determined by voltage that is applied? It is an open loop circuit right? So what is the factor that induces the motor to draw more current at lesser voltage? Please.....
- I didn't see your first posting but anyway let me have a go! Let's assume it's about an ac motor. As long as such a motor is working reasonably close to its design parameters its speed will be pretty well constant (if it's a synchronous motor then exactly constant). Its load will apply a torque to the motor shaft and this torque multiplied by the speed defines the load (mechanical power). If the speed is constant most loads (e.g. pumps) will demand a fixed torque so the motor will see a fixed mechanical power demand even as voltage varies. The motor does not draw voltage. The voltage is supplied by the user to the motor. The product of voltage and current is the electrical power to the motor ( to a first approximation - there is an adjustment for something called power factor but for explanation purposes we may set that aside for the moment). So the motor draws current to make its electrical power intake equal its mechanical power output. If we drop the voltage V supplied, the motor will automatically compensate by drawing more current I to keep V.I constant. How the motor knows to draw more current requires a fair depth of explanation. Basically an induction motor will slow down very slightly which increases the current demand and in a synchronous motor the load angle will increase slightly. Somewhat more basically, we have to do with two equations you may know : F=Bli and V = Blv which give the force F and voltage V in a conductor of length l carrying current i and moving at speed v in a magnetic field B. So if we reduce V then (at constant l and v) B must reduce. Reduced B (see first eqation) demands increased i in order to maintain F (F being the source of the output torque). Edit your question if you need more explanation.
- Q:It spun freely and I was able to spin it and it started again but then after about 15 minutes it quit altogether. No humming anymore either.
- Hello. My name is Richie. I am an electrician and a home improvement expert. I will help you the best I can. More that likely it is the motor. Smell the motor and see if it smell burned up. If so, you can replace it yourself by looking online at Grainger and getting a new motor. Grainger isn't cheap but they will have it. You will need to take off the old one before you take it to get a new one. Good luck and God Bless. Jesus Christ loves you.
- Q:I need this for my lab report.
- Induction AC Motors are referred to as asynchronous motors or rotating transformers. This type of AC Motor uses electromagnetic induction to power the rotating device which is usually the shaft. The rotor in Induction AC Motor products typically turns slower than the frequency that is supplied to it. Induced current is what causes the magnetic field that envelops the rotor of these motors. This Induction AC Motor is designed in one or three phases.
- Q:If u could tell the functions of each part it would be of gr8 help to me!Thankyou in advance!
- This Site Might Help You. RE: What are the various parts of an AC motor? If u could tell the functions of each part it would be of gr8 help to me! Thankyou in advance!
- Q:I need to know what are the specifications that an AC Motor must have on its nameplate...and who says it (ISO,Nema, DIN...)
- i think of it truly is an argument of tesing the ac/dc motor by potential of turning it on and not using a load and see what's Q (reactive potential) representing the loses. yet in any different case is that in case you comprehend the entire potential S and the lively potential P and Q = S - P.
- Q:Which one uses magnets for its rotor and which one uses a wire loop i'm confused
- Synchronous motor has a rotor (the non-stationary part of a rotary electric motor) spinning, that is with coils (wire loops) which produces a magnetic field which drives it. Contrast this with an induction motor, which must slip in order to produce torque. An asynchronous motor (or induction motor) is an ac motor where power is supplied to the rotor by means of electromagnetic induction. This converts electrical power to mechanical power in its rotor (rotating part). Hope this helps...
