Crane electric motors - features, purpose, types

Many machines and mechanisms, due to their specific nature, are forced to operate under significant overloads. This is especially true for lifting devices that use AC and DC crane electric motors. They are characterized by intermittent operating cycles and a wide range of speed adjustments. Their work is accompanied by shaking and vibration, and in metallurgical production they are additionally exposed to vapors, gases and high temperatures. Therefore, the main characteristics of crane motors differ significantly from similar general-purpose devices.

General information about crane motors

Application area of ​​crane motors

Crane (or, as they are also called, crane-metallurgical) electric motors are widely used in the construction, energy, mining and metallurgical industries. The main purpose of crane electric motors is to ensure reliable operation of the drive of cranes and other mechanisms operating in short-term and intermittent modes, as well as to drive mechanisms operating with frequent starts and electric braking (tower, portal, gantry, bridge cranes, elevators and various lifting mechanisms).

Design of crane electric motors

Crane electric motors of the MT series (MTF, MTH, MTI) are manufactured with a wound rotor, electric motors of the MTK series (MTKF, MTKH, MTKI) are manufactured with a squirrel-cage rotor. The range of crane electric motors (with squirrel cage and wound rotors) includes more than 80 standard sizes with rotation axis heights from 112 to 280 mm. All crane electric motors are manufactured as standard for temperate climates (climatic modification U1), and also, at the customer’s request, can be manufactured for operation in tropical climates (climatic modification T1) and for work in northern latitudes (version UHL). Due to their design features, all crane electric motors are capable of operating in “hot” shops of metallurgical plants. The crane motors are cooled using external airflow (IC 0141). The standard degree of protection of crane electric motors is IP44, the degree of protection of the terminal box and hatch of the slip rings of electric motors is IP 54.

Operating conditions for crane engines

The values ​​of environmental climatic factors for normal operation of crane electric motors are regulated by GOST 15150 and GOST 15543.1 for various types of climatic modifications:

• the upper value of the operating temperature of the ambient air is not higher than 50°C, the lower value of the operating temperature: for U1 – not lower than 45°C; for UHL1 – not lower than 60°C; for T1 – not lower than 1°C.
• relative ambient humidity: for climatic versions U1, UHL1 - 80% at 15°C; for climatic versions T1, O1 - 80% at 27°C.

Crane electric motors are designed for operation in the following conditions:

• altitude above sea level – no higher than 1000 m.
• the environment is not explosive, does not contain live dust, aggressive gases and vapors in concentrations that destroy metals and insulation.
• dust content value - up to 100 mg/m3.

Features and purpose

Crane electric motors should be understood as electric drive units that move various mechanisms of crane installations. When considering lifting cranes as a component mechanism consisting of various components, the purpose of electric crane machines has several directions:

• Moving the crane installation itself along rails;
• Movement of crane installations in a vertical plane;
• Rotation of crane elements;
• Movement of lifting mechanisms to move the hook.

All manipulations with the load are carried out over a short-term period, therefore the operation of the crane electric motor must be carried out in intermittent modes, in which case the rotation speed range changes significantly. Because of this, they do not have to make long-term efforts, but the unit undergoes short-term loads and the effects of inrush currents. In addition to standard situations, the windings can be subject to overloads and overheating, therefore mechanism drives are manufactured with the following features:

• In most cases, these are closed-type electrical machines; the outer casing allows them to be protected from mechanical influences during operation. For metallurgical units, exceptions may be made, since the increased temperature makes it necessary to ventilate the windings.
• General industrial electric motors have improved insulation in terms of resistance to high temperatures, usually classes F and H. This allows the insulation resistance level to be maintained when it is heated.
• Relatively low shaft inertia, which reduces electrical energy losses during transient processes at operating frequencies.
• The magnetic system has good conductivity, which creates a powerful flow that can overcome serious load forces.
• A high level of overload relative to the rated operating currents is allowed. The coefficient can reach from 2 to 5, which is considered normal for a crane electric motor.
• Large spread of rotation speeds between minimum and maximum modes.

Some requirements for crane electric motors may be eliminated due to the peculiarities of operating modes and technical processes. And some types of specialization will be dictated by the type and design of the motor.

EXAMPLE OF DESIGNATION FOR CRANE ELECTRIC MOTOR TYPE 1:

• MT, AMT, DMT – series name

0…7 — dimensions of the outer diameter of the stator sheets

0…1 — engine modernization>

1…3 - size of the length of the motor stator core

1, 2 — accommodation category

What are the differences between crane engines?

An electric motor intended for crane equipment is usually produced in a closed version. The resistance class of insulating materials to high temperatures corresponds to F and H.

The technical characteristics of these units are characterized by a minimum moment of inertia of the rotor and a low rotation speed. This allows you to significantly reduce energy losses during transient processes. High resistance to overloads is ensured by a large magnetic flux.

There are indicators for the values ​​of short-term torque overloads, which in hourly mode range from 2.3 to 3.5 for AC motors, and 2.15-5.0 for DC units. The maximum permissible operating speed correlates with the nominal speed by a factor of 3.5-4.9 for direct current and 2.5 for alternating current.
