Overview

The motor is a variable-
mechanisms in very harsh
frequency
working
，three-phase asynchronous motor exclusively designed for tower cranes and other similar travel mechanisms. It is applied to the travel
conditions such as construction site or open pit quarry

Features

Introduction of a spline drive shaft, with excellent mechanical bearing capacity;
Variable-frequency speed regulation in a broad range with high efficiency, small starting current, big starting torque and strong overload capability;

Duc to compact structure, small size, lightweight, high reliability, it can be quickly braked and accurately located, suitable for frequent starling and braking;

Introduction of a new brake (national utility model patent. Patent No. ZL201120188173.2, ZL2011201881643). It can buffer the startup to mitigate the impact on the
tower crane. In addition, the motor has very high security and reliability, and can reduce the maintenance time, and cut down the maintenance cost;

A thermal protection component is buried into Lhe stator winding, so the motor operation is more secure and reliable

Q:How to use single-chip microcomputer to control AC motor 65KTYZ, what should be used to control the chip? Please give expert advice. It is better to give access to each interface.: This motor is single-phase or three-phase, ah, second power, how big, these need to know.If it is a small single-phase or three-phase motor, AC motor can be controlled by solid-state relay or by small AC contactor control relay, if it is large, it is best to use the second scheme just said. It is so simple. What if there are special requirements that is another, I can talk.

Q:I was curious if I rewired the AC motors on both the squirrel cage fan and outdoor unit to DC, and hooked solar panels directly to with battery backup, would that be anymore efficient than converting to AC?: It really would not do you any good. The only power you'd save would be that which an inverter draws, and that's minimal. We live off grid and I can tell you that running a central a/c unit with solar will be exceptionally costly to setup and maintain. We use wind and solar and batteries and have over $25,000 in our system and I could not power a 220-v a/c unit.

Q:This is a motor from a sliding gate, I noticed that it was not working properly, so i opened it and put it into manual mode(releasing the load and making it move freely) but then once it is turned on it it rotates a little and then stops again a little , stop and then works ok and when it is turned off it runs for another small time. Before it worked perfectly fine. Is this a problem with the capacitor? Thanks: may be due to oldage so clean and do well lubricants

Q:I have an AC motor that has a resistor. Why are resistors used? Any answer is appreciated. As simple as you can. Thanks: AC motor does not need a fix resistor ! Perhaps it was a capacitor ? Show the picture if you could or read what it marked on it.

Q:i have 380/480volts 50-60 hz 7.5 kw 3 phase AC motor pump. my power supply is only 208 vac. while running it gives only 19 amps for each phase, but the motor is very very hot.: you are using the 'extra'' legg off the transformer to get the 208 volts. why? the motor takes 3 hot leggs not 2. Get an electrician to wire it correctly.

Q:What is the power factor of single phase capacitor start motor while running under load or without load. Some motors have capacitor permanantly connected in series winding. What power factor of these motors?: I do not believe that there is a power factor for single phase motors. The power factor is a measurement of phase angles in relation to each other. Capacitors are used to bring the phases more closely together or above 80%. Power factors are important for high end users of three phase motors. The closer to 100% in phase the less the losses. In other words if your actual use is 100 KWH the if the power factor is 80% you will be charged for 125 KWH. Power factors are measurements of the system supplying the power.

Q:what determines the speed of electric motors?: There are many types of motors. If its an ac induction motor (many ac motors are induction type) then the speed is determined by the frequency of the mains and the number of poles in the motor. This gives the speed that the magnetic field rotates, the actual shaft will be slightly slower and varies very slightly with load. For other motors the answer may be different.

Q:thats an electric motor that can power your car...: The okorder Click on: EV AC MOTORS And on the bottom of that page, click PRICE LIST. It looks to me like 30kw will cost you $4,732.00. You'll need an AC power inverter, and a few assorted other things to make an electric car with it.

Q:I am new to all this. BUt I've read about an quot;h bridgequot;? if you could just point me towards those 2 things It would really be helpful. Trying to shop without knowing what to look for is rather difficult.If you need more info, then could we just assume that I am trying to run a DC drill motor, and the AC one can be anything really, just to get started, as I'm not sure what appliances it would run yet.The goal is just to hook up the arduino uno for use of larger things.... THANKS A MILLION!!!: An okorder /

Q:Im building a formula hybrid vehicle, and Im wondering what would be the difference from using AC and DC motor: DC motors are easier to control, especially using digital (computer) systems. DC Control systems are usually more reliable than AC Control systems AC Motors require a sourcde of Alternating Current, but ALL batteries are Direct Current (DC). Therefore, you need what is called an AC Inverter to make Alternating Current (AC) from Direct Current (DC)batteries. This means more expense, AND more parts that could possibly fail, thus reducing the reliability of the vehicle and making it more expensive to repair.
