Crane motors: Overhead crane motors & Gantry Crane Motors

Overhead crane motors, gantry crane motors, hoist crane motors, and other crane motors are covered in this overview. Crane motors of many types are offered to you, including soft start crane motors, three-in-one crane motors, and wound type crane motors. Learn about the benefits of each type of crane motor and choose the right one for your crane.

What is crane motors? Crane motors are one of the most important electric equipment, which is widely used in the hoisting system and long travelling system or driving system, etc.

Classifications of motors

According to different standards or categories, the crane motors can be classified into various types, including the DC motor, AC motor, Current motor, Induction Motor & Synchronous Motors ,Electric Motors & Servo Motors, etc.

DC Motor & AC Motor

The overhead crane and gantry crane motors can be divided into DC and AC motors based on their working power. According to the operating principle, DC motors are separated into brushless DC motors and brush motors, while AC motors are divided into single-phase motors and three-phase motors.

And also according to the voltage of the crane motors, they also can be grouped into 0.25 KW, 0.4 KW, 1.1KW, 1.5 KW, 2.2 KW, and 0.75 KW, etc.

Current motor, Induction Motor & Synchronous Motors

Motors for overhead cranes and gantry cranes are classified as direct current (AC) motors, induction motors (AC motors), and synchronous motors based on their structure and operating principle.

Electric Motors & Servo Motors

Motors for overhead cranes and gantry cranes can be separated into Electric motors and Servo motors based on distinct motor controls.

Servo motor

Servo motors are widely utilized in a variety of control systems because their voltage input signal may be transformed to the mechanical output of the motor shaft. To achieve the control objectives, the drag element is controlled.

AC servo motors and DC servo motors are the two most common types of servo motors. The first servo motor is a general DC motor, which has a low control accuracy and can only be used as a servo motor with a general DC motor. The current DC servo motor is a low-power DC motor with armature control and field control, though most of the time armature control.

Stepping motor

Stepping motors are mostly employed in the production of CNC machine tools. Because digital pulse signals can be directly transformed into angular displacement, the stepping motor does not require the installation of an A/D converter. The stepping motor is often regarded as the most effective CNC machine tool actuator. The stepper motor can be used on other machines outside CNC machine tools, such as an automatic feeder in motor or a generic floppy disk drive motor in the printer and plotter.

Torque motor

Torque motors have low speed and strong torque characteristics. The AC electric motor torque is often used in the textile sector since it has the same construction as single-phase asynchronous motors.

Switched Reluctance Motor

A new variable speed motor is the switched reluctance motor. The switching reluctance motor's structure is exceptionally simple and robust, with cheap cost and high speed performance, providing significant competitiveness when compared to traditional motor control and a large market potential.

Brush-less DC motor

Brush-less DC motors have superb linearity, a wide speed range, a long life, are simple to maintain, and produce little noise. When compared to brush motors, brush-less DC motors are free of a number of issues created by the brush, allowing the motor to be used in a variety of control systems.

DC motor

Because the direct current motor, commonly known as a DC motor, has characteristics such as strong speed performance, ease of starting, and the ability to start with loads, it is still widely used today, particularly in the SCR after the DC power supply.

Asynchronous motor

Asynchronous motors have a simple structure, are simple to make, use, and maintain, operate reliably, and have a low mass and cost. Asynchronous motor-driven machine tools, pumps, blowers, and compressors are among the most common applications.

How to select motors for your cranes?

Due to the various types of crane motors, there is a question confronted in front of us: How to select the driving motors for your cranes?

Generally speaking, the basic specifications of your overhead cranes or gantry cranes has be bear in your heart, which will set a basic requirement on the function of crane motors in terms of start, brake, speed regulation, load, torque, synchronization,etc.

Under normal conditions, when selecting a motor, the model, type, rated speed, rated voltage, and rated power of the crane motor should be taken into consideration. What's more, the motor manufacturer, after-sales warranty period, service life, and maintenance services are also important when selecting. If necessary, the special properties or requirements should be bear in mind such as corrosion resistance and other factors.

And also, when choosing a suitable driving or lifting motor for cranes, it is necessary to consider whether the shape, structure, and weight of the motor can be compatible with the overhead crane, gantry crane or jib crane, and whether the motor can adapt to the environmental conditions, working system and working load of the crane application,and so on. In the following, the tips are for your reference to select the right crane motor or hoist motor. And more specialized recommendations or suggestions, please feel free to contact us.

1. It has two options to select the overhead & gantry crane motor when the ambient temperature surpasses 40 ° C;

First, use a motor with insulation Class H, which is adequate for temperatures up to 60 ° C;
second, use a motor with insulation Class F, but the first approach takes precedence.

2. When overhead and gantry cranes are used at altitudes greater than 1000 meters, the motor capacity must be increased.

Motors having an IP54 protection class should be used in outdoor overhead cranes and gantry cranes.

4. Because overhead cranes and gantry cranes do not undertake continuous long-term labor, you do not need to choose a motor with S1 continuous duty or a JC100% electrical connection rate. Based on the working class, the overhead & gantry crane should select motors with the appropriate working level and duty electrical connection sustained rate. (The particular way to choose varies depending on the control mode.)

5. Lifting motors with S2 duty, whose operating system allows for 30 minute and 60 minute performance, should be used for overhead and gantry cranes that are operated continuously for more than 10 minutes. The choice of a 30 minute or 60 minute duty motor should be based on the institution's actual running duration. The S4 duty motors are always the best choice for overhead crane and gantry crane hoisting mechanisms.

6. According to the matching YZR power value to calculate, the frequency motor normally does not offer the specifications for S2, S4, and S5 work systems.

7. For the overhead crane and gantry crane, it should use motors with as few poles as feasible, if permitted by general requirements.

8. Once the overhead and gantry crane motors have been chosen, they should be overload and fever tested.

9. It is necessary to connect mechanical design components, which should contact the electrical relevant persons, using stator voltage and speed control, frequency speed control system, or other information feedback and other particular requirements.

10. The overhead & gantry crane motor should be set as user requirements if the user has particular requirements.

11. The motor selection for overhead and gantry cranes should be adjusted according to the actual scenario in order to make the motor cost-effective, reliable, and create a roughly optimal result.

Types of crane motors are available such as, 3 phase crane motor, Geared crane motor, Crane high torque motor, Heavy duty crane motor, and Crane end carriage motor, etc. According to your lifting requirements, the most suitable crane motor will be provided for you.
