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?
- Yes. It will generate power back into the AC supply. Some induction motors can be coaxed into generating into a load with a capacitor attached but without an AC supply connected. However, that is not a very reliable or versatile set-up.
- Q: There is no magnets in an induction motor so is this even possible.
- A vehicle's charging system is a three phase alternator - and they work just fine AC or when the output is rectified to DC.
- Q: I check with our supplier. they told me that we have to load on motor then only it will show correct rpm ( both low and high). what is the maximum load for this motor It is shoiwng 1.3 amp
- DOES THE MOTOR HAVE A 2 SPEED switch, and what are you using it for? 1.3 amps has to be 120 volt. its probably a 2 speed motor without a switch. in that case it has to be under a load. if this helps you cant hear it change speeds, even under a load, i really need more info before i can help you. how are you checking the rpms? butch
- 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
- It has a smaller DC motor (maybe 200 watts) but it is run thru a 1:160 gearbox or so. With a capability of pulling about 800 lbs vertically and 3000 lbs in rolling wheel mode it has the 3000N of force you need. You could mount the winch to a small frame and simply hook the cable to a box with a sliding piston that crushes the can.
- 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??
- Reverse the start windings on the motor. #5 #8.
- Q: The difference between DC motor and AC motor
- The construction of three-phase induction motor is also divided into two parts: stator and rotor.(1) stator:The stator is the fixed part of the motor, which is used to produce rotating magnetic field. It is mainly composed of stator core, stator winding and frame.(2) rotor:The rotor is the main part of the rotor. There are two kinds of rotor, squirrel cage and wound rotor. Grasp their respective characteristics and differences. The squirrel cage type motor used for medium and small power (100K or less) is simple in structure, reliable in operation and convenient in operation and maintenance. Winding type can improve startup performance and speed regulation. The air gap between stator and rotor will affect the performance of the motor. The general air gap thickness is between 0.2-1.5mm.Master the wiring method of stator winding.
- Q: Is it an universal motor which works on ac or dc voltage,how does it work,speed regulation rheostat foot pedal,I mean can someone explain me technically how a sewing machine motor works,and how to connect it back after rewinding,thank you.
- Sewing Machine Motor
- Q: How to speed the AC motor?
- The speed of three-phase asynchronous motor is expressed as:N= (60 * f / P) * (1s) =n1 (1s),N - motor speed (R / min, revolutions per minute); F - power frequency (Hz);P - the polar logarithm of an electric motor;S - slip ratio of motor, s= (N1 - n) / n;Synchronous speed n1 motor, n1= (60 * f / P) (R / min).There is a way to change the speed of an electric motor:1, change the power frequency;2, change the number of poles of the motor;3, change the speed difference.
- Q: The engine would be for a boat so another question i have is does anyone have any idea how to calculate or figure how many kw it would take to run a dc motor like that obviously it would not be running at 715 hp the whole time because that is only needed for acceleration. Thank you!!!!!!!
- It would likely be that a ship would be powered by multiple electric motors rather than a single motor, but even if the specs called for a single motor, yes electric can be made that powerful.
- Q: is it necessary to use both ac and dc motor in car??
- I thought DC only! Car batteries are low voltage device and short distance from the generator so no point to generate AC voltage and convert back to DC for charging the battery.
