As you know, a building lift is a mechanism that is responsible for carrying, transporting and moving all kinds of loads. The force in construction lifts in different devices is created by a variety of mechanisms.
As you know, construction lifts have different components, including electric motors, gearboxes, structures, power switches, pulleys, tow ropes and buckets.
Before buying an electric motor suitable for building lifts, we must first know the points and follow them, which we will get acquainted with in the following sections.
Important points in choosing electric motors
If you have noticed, on the license plate of the lifting electric motors, information has been inserted in which the specifications of the electric motors have been briefly presented to the users.
Information such as whether the electric motor is single-phase or three-phase, the amount of input current, the amount of power consumed and the manufacturer.
Material lifting motors, also known as electric motors; they are divided into two general categories, single-phase and three-phase. This is the most important indicator of electrons on their license plates.
Another important information that must be considered is the IP number. The IP index determines the permeability of the electromotor against moisture and dust. Note that the higher the number, the more impermeable the motor. IP 54 is typically suitable for construction lift electro motors.
Note, however, that this IP does not mean that it is suitable for high humidity and rainfall conditions. In motors that are single-phase, more attention should be paid to the capacitors and the motor clutch.
A capacitor is also an electrical component whose job is to store instantaneous current, which is instantly placed in a circuit in a single-phase motor. Note that this part is essential for starting the engine.
In single-phase motor construction lifts, two capacitors are used, both of which are responsible for starting and starting the motor. Note that if one of the capacitors does not work properly, the device motor will not start properly or it will start very hard.
Of course, this problem is diagnosed by experts. Note that in electric motors there are two windings, one of which is used for starting and the other for permanent operation of the device.
If the clutch of the device has a technical problem and if the platinum part does not have the correct settings; the engine of the device makes a sound but does not start.
Choosing the right electric motor for construction lifts
An electric motor, also called an alternator. Note that the electric motors of construction lifts are selected according to criteria such as load carrying capacity and height.
In the continuation of this part of the article, we have brought the power of some of the electric motors in construction lifts with their motor power and gearbox, and we have examined each of them.
1. The first electric motor for construction lifts can carry a capacity of 300 kg. The motor power of this type of electric motors is 3 hp and it is single phase. Also, the gearbox of this electric motor is VF86.
2. The second electric motor can carry a capacity of 500 kg. The engine power of this type is 5.5 hp and has three phases. Also, the gearbox model of this electric motor is VF110.
3. The third type of construction lift electric motors can withstand a capacity of 750 kg and their motor power is 7.5 hp. Also, the motor of this type is three-phase. The gearbox model of this electric motor is also VF130.
The fourth type of construction lift electric motors has a load capacity of 1000 kg and its motor power is 10 hp. The engine of this type is three-phase and its gearbox model is VF150.
Note that there is a difference between the nominal power of the engine and its actual power. For example, in a three-horsepower engine, due to the low amperage at the moment, it is better to carry an aluminum body of up to 200 kg.
But for example, the electric motor is Alco Yugoslavia 78, which due to its egg-shaped design, its design quality can handle loads up to 350 kg. Construction lifts with a large load carrying capacity of 300 kg are the most popular option among users due to their single phase.
Another reason for the popularity of these lifts is the possibility of direct use of city electricity, which is one of the advantages of using construction lifts. The only problem with single-phase electric motors is its low starting torque.
In general, it can be said that the starting or starting torque in single-phase motors is less than that of three-phase motors.
In general, it can be said that due to the high tensile current at the start of single-phase electric motors, their coil material should be all copper. Note that the presence of two auxiliary dry capacitors in single-phase electric motors is essential.
Also note that to choose the electromotors of construction lifts, the amount of load carrying and all available standards must be considered.
Never disregard existing standards to reduce costs, as this can cause a great deal of financial and personal loss. There are also some electric motors that are used for building lifts that are supposed to carry or move less load.
These electric motors are called lifting dynamos, and their use has many advantages, such as their low price compared to other similar products. Finally, it can be said that very careful selection of electric motors for construction lifts.The reason for this is that this part is of special importance in forklifts.
