Lift engine and crane
The electric motor and dynamo of the building lift is the most important member and part of the lifting systems in buildings in order to facilitate civil and construction activities. In fact, the main driving force in such elevators is provided directly by the electric motor for the elevator. This type of electric motors can have different types based on the required power and capacity of the work. For example, for small construction works of one or two floors, capacities lower than 5 horsepower may be needed. It is in such cases that the difference of construction elevators becomes clear. Another important member of elevators is the construction elevator gearbox, which is usually the same for most elevators up to the weight of 300 kg. But the electric motor is not like this.
According to the usage and power required in construction works, you should use the electric motor according to your specific capacity. Construction lifts that are used in the construction industry today usually have the ability to move up to 1000 kg of weight vertically. Now, these elevators may be of the elevator type or of the normal type and for moving people.
If we want to express the most important components in the type of construction lifting dynamo, we must mention their required power and capacity. In the design process of building elevators, the need is considered first. That is, the manufacturing company ranks its production list of construction lifting products from a technical point of view; From lifts with low capacity and power, to medium and heavy lifts. Then, for each of these categories, he puts the most suitable electric motor on the lifting device. In general, in light construction elevators that have the ability to carry a load of up to 300 kg, a low-power single-phase two-capacitor clutch motor is used. But in more powerful types, single-phase electric motors are not responsive and it will be necessary to use more powerful types of electric motors. Here, by using a three-phase building lift motor, a capacity is created that the lift can even carry 1000 kg loads in the upper and lower building. slow down High-capacity electric motors usually have a power equivalent to 10 horsepower, which will also be responsible for heavy construction activities.
The most important criteria in buying a lift engine
In the selection of electric motors for construction lifts, there are important points that may not be stated by many sellers intentionally or unintentionally. Paying attention to these points can guarantee the use of the best type of motor for the construction lift. The first important point in choosing this part of the construction lift is to pay attention to the type of electricity used in the building. If your building has regular city electricity, you cannot use single-phase electric motors and you will have limited choices. This means that if your construction work has a heavy volume and dimensions, you should first think about replacing the building's electricity. After that, you can use three-phase elevators with different powers to do your construction work.
The next point that is usually paid little attention to when buying a construction elevator motor is the motor starter. In all types of construction lifts, starting and starting power of the engine is very important. Because the main part and the most difficult part of any engine to create weight movement in the vertical path is the starter. This point is more prominent in the purchase of single-phase electric motors. Another important criterion for purchasing lifting dynamo in buildings is the type of motor insulation system. In many engines, based on functional design, weather conditions are considered and insulation is done based on it. IP is actually an index that shows the type and degree of penetration of external factors such as dust, moisture and thick particles into the engine. Most of the electric motors produced in countries like Iran and China, due to the need The market is of 54 IP type. This type of electric motor is not suitable for working in rainy and humid weather conditions. The mentioned motors do not have proper and safe insulation and protection against moisture, and even if they are used in such conditions, they must be strictly protected.
