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:I know over spinning most AC motors will turn them into AC generators. Is the same true of shaded pole motors?
- Nonsense , AC motor could not generate a drop of AC power no matter how hard you spin it.
- Q:How can I control the RPM of an industrial motor of 7 horse power? I need it to have high torque and low RPM, like 100 per minute.
- Definitely do your homework before buying, though. If you just size the drive to the motor horsepower, you may end up with too small a drive and a lot of expensive smoke.
- 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:I own a condo unit- a/c stopped working. a/c company came out and said i need to replace the blower motor to my a/c unit- told me it would cost $1,280. Blower motor is 1/6 hp 120 volt. Does this price sound right?
- sounds like the bearings for the motor is shot. pass to the producer of the A/C unit internet web site or there should be the producer of the motor and its style style on the motor itself. pass to their web site and word the availability and value. they'd have a distributor close on your area so that you do not ought to attend to be shipped.
- Q:Why in general larger aircraft make use of both AC and DC electrical systems.?
- AC motors and controls can be made smaller and lighter, especially when driven at 120V and 400 hz. Almost all, if not all, systems that are intended for normal use with normal power will be AC. DC, on the other hand, is the old stand-by when down to just battery power. If a pilot arrives at a dead airplane, with no external power (AC), how will he get the thing running if it requires A/C? With one or two batteries, one DC fuel boost pump, a DC starter on the APU, DC fire detection and DC fire fighting systems, he can safely get the airplane up and running, and if a fire breaks out during the process, he can fight the fire. If there is a loss of all AC generators, then there needs to be some DC powered stuff from the battery (basic flight instruments, basic lighting, etc.) to allow continued flight while attempts are made to restore the AC. On the Boeings, the fallback really important stuff will be found on the hot battery bus, battery bus, DC transfer bus, and standby DC bus. The Airbus probably does the same thing using different names.
- Q:What's the difference between direct current motor and AC motor?
- A direct current motor is a magnetic field that does not move; a conductor moves in a magnetic field; an alternating current motor rotates in a magnetic field, and the conductor does not moveDC motor consists of stator winding and rotor winding of stator winding. The magnetic field is produced. When the direct current. The stator windings produce fixed polarity magnetic field. The rotor energizing force in the magnetic field. So the rotor in the magnetic field force is rotating. The DC motor structure is complicated. The cost is high.
- Q:What are the classifications of AC motors?
- According to the different rotor structure, three-phase asynchronous motor can be divided into two major categories, squirrel cage and winding. Among them, squirrel cage is the most widely used.
- Q:I have a 1991 Volvo 240. It has some electrical problems. the right passenger window goes really slow. and I had the AC compressor disconnected. so, the air conditioning unit and the windows run on the same fuse. When the AC is connected, and I try to use the windows, it blows the fuse. My mechanic said it was a bad AC compressor, but I got to thinking. could the window motor be what is blowing the fuse?
- I don't think it's your AC compressor on the same circuit, there isn't much electrical about the compressor except the high and low pressure switches. I think he meant the blower motor and the window motors are on the same fuse. Try using you heater and putting down the window, the heater and the AC use the same blower motor.
- Q:I will be really happy enough if this answer is answered more reasonably in a simple explanation. What is the real difference between a DC and a AC motor? I know about the alternating and the direct current. One flows in reverse ad the other in one direction. But that's not clear enough. Please help me out.
- A good explanation requires diagrams which can't be included here. It is important to understand that the direction of the force on a wire in a constant magnetic field depends on the direction of the current. Reversing the current direction reverses the force. The force's direction must change each half-rotation to keep the motor turning. This force-reversal can be achieved by: - in a DC motor using a split ring commutator and - in an AC motor having two slip rings and using the fact that AC reverses direction each half-cycle. See link.
- Q:there seems to be cold air trickling out of the vents. my return filters are good. how do i check the blower? where is it?
- The blower is the same blower you furnace uses inside the furnace if it's central A/C. Basically the same if it's a heat pump. The pump is outside like the A/C condenser is. The blower is inside the home as well. Good luck, its getting hot lots of places.
