Overview
the motor is a variable-frequency, three-phase asynchronous motor exclusively designed for the tower cranes and other similar amplitude mechanisms. It is applied to the
amplitude mechanisms in very harsh working conditions such as construction site or open pit quarry
Features
With introduction of spline output shat, it has good mechanical bearing capacity and excellent assembly performance;
Motor installation interface has the same size with original tower crane (POITAIN series), making it easier for switching and upgrading of old products
The motor is a variable-frequency motor featuring a wide range of speed regulation, small starting current, big starting torque and overload ability;
A thermal protection component is buried into the in stator winding and wired into the motor temperature protection control system, making motor more safer and reliable;
New brake (national utility model ZL201101881732, ZL201120188164.3) with higher safety and reliability this reduces the maintenance time and cost compact structure, small volume, lightweight as well as high reliability, so it can be braked quickly and positioned accurately. It is suitable for frequent starting and raking
- Q: Is permanent magnet synchronous motor AC servo motor?
- First of all, the classification of motor: servo motor is divided into AC servo and DC servo, in which AC servo and synchronous and asynchronous points. Permanent magnet synchronous motor (PMSM) is a kind of synchronous AC servo motor.
- Q: can avr improve power from dc to ac inverter?
- If, I understand your question properly? The most that the AVR chip will do for you? Is smooth out the wave signal of the AC power. As, AC over your home power lines comes in as a sine wave. Most common inverters are not capable of producing true sine wave. Most, at best produce a modified sine. Which means an inverter is just fine for small appliances. Like a coffee pot, small refrigerator, etc. But, create static and white noise for laptop, TV's radios, etc. These require a pure sine wave AC signal. So, yes, it will improve the purity of the power. But, nothing to boost/amplify power.
- Q: I have it all disconnected and out of the unit. I am having trouble getting the blades off of the rusted shaft. (two rusted set screws) Any tricks out there on how to loosen them without damage to set screws? Any other advice would also be helpful...first time at this.
- i use liquid wrench, let them soak and give a more than a little tap, but not a real hard smack with a hammer, just several sharp raps. this helps to splash out the first layer of softened rust and aids the second application to more readily penetrate. hope this helps
- Q: Im wondering how many Volts/Amperes a regular small electric motor can handle.
- DC motors are known for their longevity and ability to be overloaded without damage. Its hard to say what motor will take what though because some quality motors will run fine on almost twice the voltage while some cheaper ones will thermally break down very quickly. If you can keep a motor very cold you can probably push it pretty far, if you have a large supply for DC power and a LARGE peltier you may be able to get a dc motor over quadruple its rated voltage. At some particular point though the wire coatings will break down so over-volting a dc motor will eventually damage the motor.
- Q: Derive the transfer function of ac servo motor?
- go through slides 21-25 for exact derivation
- Q: I'm confused - Does an induction motor used for an automobile convert DC battery power to AC? I'm under the impression that induction motors need AC power to run, so how can this quot;ACquot; motor use DC power to make AC? I'm aware that there are AC/DC inverters but wouldn't that make the whole system less efficient since it has to run through this extra device to make power?
- There are no AC motors in an automobile. DC power is produced in an automobile by an alternator. An automobile alternator is a 3-phase, wound-field synchronous generator that converts mechanical power from the engine to AC power. The AC power is converted to DC power by s simple rectifier that is usually mounted inside the alternator.
- Q: I'm building this machine which will enable user to change the speed of the motor, rather frequently. The motor may have to work in speeds much lower than its maximum speed for long periods or even always. Should I use a DC motor with electronics to control the speed? Or an AC motor coupled with an inverter?
- Hi. AC motors are designed and built differently than DC motors. AC motors take advantage of the 60 hertz clock of a power line (or 50Hz in other countries) - this means the power line changes phases 60 times a second - to rotate, while DC motors are designed with the voltage level applied. You can control them both, but with different means. The easiest to control is the DC motor (change the potential (the voltage) and it turns slower or faster.
- Q: I know that Watt, RPM Torque are connected each others, but, with the same RPM Watt, are there unordinary electric motors out there that have very higher torque than ordinary motors ( especially 220v 1 phase AC motors ) ?Can someone give me the website address about it ?
- Not okorder /
- Q: I'm looking for an AC Motor, with high torque (around 130-200lbs/ft) that doesn't use more than 5kw. Let me know your thoughts... Tony
- y dont u go to ure local spares shop or check the yellow pages for car spares.
- Q: Is it possible to add a speed control to this electric fan ? If so I will appreciate any quot; linkquot; with information of the kind of controller I may need. I need it running at variable speeds.
- Because it is a AC motor you will need a one phase inverter! Just google for one phase inverters and see one that fit with the power and voltage of your fan!!! good luck!!!
