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:as an alternative I want to generate electricity domestically at my home. I want to use simple motor as a generator. Instead of giving supply to motor I with attach a propeller to motor shaft and drive it.: You can use a synchronous motor, but it may not be easy to find a synchronous motor of the size that you have in mind. The most popular generator for this type of project is an alternator from a junked car. You must turn an alternator 1000 to 2000 RPM to get it to work.

Q:need to know how many 12 volt batteries it will take to run the motor: The inverter is the most easily implemented and usually least costly solution. As as informational note in large power applications a motor generator consisting of a dc machine coupled to a synchronous ac machine is used as it is more efficient and produces a cleaner ac waveform than an inverter. it has huge first and maintenance costs, however, which make it impractical for small to moderate sized applications.

Q:How many kW or more AC Motors should be started with the starter?: Starting of an electric motorArticle 2.3.1 when starting an electric motor, its terminal voltage shall be able to guarantee the starting torque required by the machine, and the voltage fluctuation caused in the distribution system shall not interfere with the work of other electrical equipment.Article 2.3.2 when starting an alternating current motor, the voltage on the distribution bus shall comply with the following requirements:First, in general circumstances, when the motor starts frequently, it should not be less than 90% of the rated voltage. When the motor is not started frequently, it should not be less than 85% of the rated voltage.Two, the distribution of buses on the lighting or other voltage fluctuations are more sensitive to the load, and when the motor is not frequently started, shall not be less than 80% of the rated voltage.Three, the distribution of buses on the other electrical equipment, can be guaranteed to start the motor torque conditions; for low voltage motors, but also to ensure that the contactor coil voltage is not less than the release voltage. Article 2.3.3 the choice of starting modes for cage motors and synchronous motors shall comply with the following provisions:When the following conditions are met, the motor shall be started with full pressure:1 when the motor starts, the voltage of the distribution bus meets the requirements of clause 2.3.2 of this specification:2 、 mechanical energy can bear the impact torque when the motor is started at full pressure;3. The manufacturer has no special rules for the starting mode of motors.Two, when not meet the full pressure starting conditions, the motor should buck start, or choose other appropriate starting method. Three, when the speed control requirements, the motor should start with speed regulation.

Q:hyundai Elantra 2000My AC blows cold and hot just fine, but It rarely blows at the max power for whatever setting I have (I keep it on 4, the highest setting). Sometimes I have to hit it to get it started. here's the funny part, If I make a LEFT turn on the road, my AC will crank up to full proper blast until I come out of the turn. If I make a RIGHT turn, it shuts off completely and only starts again when Im out of the turn or if I kick it after. Anyone know how to fix/clean a blower motor? I really dont want to have to replace it. Thanks.: provide it a splash time, it may desire to be some thing (a splash bit paper grew to become into in mine) grew to become into caught and you cured it. you're able to be able to place a drop of oil on the motor shaft. If the vibration and noise persist, evaluate changing it.

Q:pump specification abbseallesspumps,hmd kontro lcie04atex6152 model: A lot of motors have 6 wires for the three windings, so you can connect them as star or delta, as required with a star delta starter. The voltage ratings will tell you though. If it is a 380V, 415V, 440V etc. motor and it is connected as star it has a lot less power. If its 220 you have to figure out whether that was for a 127/220 or a 220/380 system. As a check, ((W x 1/PF) / Amps) from the nameplate gives the phase to neutral voltage, or W/A is close enough to tell. Always check the running current when you have installed a motor. Don't forget that the phase rotation may be important for a pump. If a water pump goes backwards there is steam and boiling water everywhere.

Q:DC three phaseField voltage 150/300Full load amps field 8.64-7.7/4.32-3.85: I would suggest going with the full load amps field. This is mainly due to the fact that it emits enough conductivity to power the voltage, but not enough to disrupt the electrical current (this is a common problem with the DC three phase and the field voltage).

Q:how can find an electrical ac motor with outer diameter of approx. 100 mm and with minimum of 500 watt. power?: What is the purpose? where you are going to use ?Is it continuouse rating Intermittent ratings.If it intermittent rating go for a smal size drilling machine with double speed or use a suitable speed controller use it for your pupose .These all high speed ,high torque ac motor it will not run continuously .It may be available in 120 volts /220 volta Ac even in 12v ,18,24v dc. If you need low torque use a table fan motor but wattage will be less.Best of luck.

Q:I'm looking for a motor that has variable speed control which could be used to control a Disco Ball.I know that quot;American DJquot; makes a motor, but it only works with the DMX lighting protocol which I don't have and is total overkill for my needs anyway.1. Does anyone know of a motor that exists other than American DJ's?2. If not, can a motor be customized and built for under $100?3. Finally, can anyone provide a URL to an motor manufacture or electronics surplus store that might answer any of these questions?I should add that using a potentiometer / rheastat (light dimmer) will NOT work with the existing motor I already own. Thanks: You state that you have a motor already. So I'll put my reply into a couple of different parts. 1) If your motor is an AC motor, the only way to properly vary the speed of an AC motor is with a variable speed motor drive. Toshiba makes some small ones (under 1 HP). But you have to manually set them and control them. They are digital. 2) If your motor is a DC motor, a variable DC voltage source is what you require.

Q:Haven't connected it yet.: A DC motor is not designed to work with AC. Get an AC motor for your application or a rated AC to DC converter. Any diode across AC (assumed source from the power company) will turn to smoke without a current limiting resistor. I suggest you bone up on some accredited electrical education before you hurt yourself or cause a fire.

Q:Hello everyone,I need help wiring up a pump motor that I just got to replace an old one. It is an Ironhorse Rolled Steel general purpose motor rated at 1 HP. It is dual voltage (115/230) but will be running it at 115V. It uses a T1-T8 system the colors are:Blue T1White T2Orange T3Yellow T4Black T5Red T8The wiring scheme for low voltage is:Line 1: Blue orange redLine 2: White Yellow blackHow do I hook this up to an AC power chord that has White, Black, Green wires?: The motor will have a label with the acronyms: RLA, LRA, and or FLA. RLA and FLA are the figures for Amperage that the motor needs. A one hp motor is likely to draw about 16 Amperes at 115V. This is beyond the limit of most common receptacles. Be sure that you have adequate power. Dual voltage is used in large motors because of the high current requirement. At 220VAC the motor draws half the amperage. Lee26loo's instructions are correct (if your receptacles are up to it).
