What are Crane Motors?

Crane motors are those which are specifically designed for the proper working of the cranes. These motors are primarily used in load-lifting cranes,  bridge cranes,  crane gantries,  and other hosting devices. These motors are highly applicable for load-lifting purposes and accurate movement of the device. This feature is primarily due to low voltage consumption and higher rotation.

The motors not only lift the load along the cranes but also carry the trolley along the rails of the crane, such as these motors lift the load in the trolley and then carry it to its exact destination. As the trolley is loaded with the load, the rails move along this road to travel it to its destination.

What Is IE4 Series Motors
Construction and Structure of IE5 Series Motors

Product Description of Crane Motors

    • The motor shows a rated voltage of 380 Volt with an optimum frequency rate of about 50 Hertz.
    • These motors are designed to lift heavy loads from one place to another.
    • Crane motors are also applicable in other hosting machinery and metallurgical processes. Such as these motors are highly useful for hauling and load-lifting purposes.
    • The device’s temperature must be kept appropriately for the machine’s proper working. Such as, in the case of a metallurgical operation, the temperature must not exceed 60 degrees Celsius. Conversely, in the load-lifting work, the machine’s temperature must be kept at a limit of 40 degrees Celsius.
    • The maximum altitude for the optimum working of the machine must be not more than 1000 meters.
    • While working, the machine expresses some sharp shocks and noises due to heavy lifting or hard work.
    • The device also shows many other specifications for the optimum load-lifting purpose.
    • These crane motors must be able to change their direction in both forward and backward orientation without any physical harm.
    • For other connection methods,  you must start the stator using the Y connection method and the rest of the connection by using the connection method.

Features of Crane Motors

    • The device shows a rated voltage of about 380 Volt with an optimum frequency of 50 Hertz.
    • The highly compact and light weight of the machine’s body makes it portable and easy to manage.
    • The motor is also applicable to work in intermittent periods. The overall working of the machine is also divided into different forms.
    • The intermittent period of the machine contains several phases, such as lifting the load and then keeping it at an appropriate destination.
    • In the initial stages of the load lifting, the machine must not show a high temperature, even at high voltage, for 10 hours or six hours In its working cycle.
    • Intermittent duty periods are divided several times according to the machine’s function, such as the time needed to start the machine, load it with any load, and then keep it in place. These times are divided into different forms, such as 150, 300, or 600 Times.
    • Intermittent series of electrical braking. It is a synchronous series that includes starting the machine, loading the device with any load, and then sudden braking, even at high speed. During this series time component is also considered.
    • During the initial stages of the motor, its points, such as its start and braking system, are almost converted into full-time working. It mainly happens through the production of heat. For this reason, you can determine the motor by the number of stars on it. The jogging ( such as the full speed will not exceed 25% of its equivalent speed ) is four times from its start. On the other side, the electrical braking (About one by third of its initial rate) is about 0.8 times more than its start.Crane motor is the most advanced product according to the time. Its primary and advanced features are listed below.
    • The benchmark working of the motor is about 3S to 40%. But if you want to insert the features according to your need, Such as beyond the speed of 2S to 5S, then you must contact our manufacturers. You need to provide your custom features; our professional team will manufacture them according to your need.
