Application of crane electric motors

Asynchronous AC crane electric motors are designed for heavy-duty operation of repeated starts-stops-reverses, with control of the rotor speed in conditions of severe shaking and vibration. Crane electric motors with a wound rotor also operate in metallurgical shops at ambient temperatures up to 700 ºC, in an atmosphere of high gas pollution and vapor formation.

Electric motors with a wound rotor operate on portal, bridge, tower, gantry cranes and intra-shop telpher systems in heavy and very heavy duty. Asynchronous motors with a phase rotor of the MTF and MTN brands are used as crane electric motors, where the letters “F” and “N” indicate the heat resistance class.

Types of crane electric motors

Due to the use of various principles for rotating the rotor in an electric motor, many of them have found wide application in the operation of crane installations. Among electric motors for general industrial use, there are AC and DC machines, asynchronous motors, both with phase and squirrel-cage rotors. Next, we will consider each of the types used for crane equipment.

Alternating current

For domestic cranes, asynchronous AC electric machines are used. A distinctive feature of such installations is good traction characteristics, but the disadvantages include the need to connect three phases at once and large starting currents. Most models are manufactured for a standard network frequency of 50Hz; such options are capable of constantly withstanding overloads of 10 - 15%.

Rice. 1. Example of an AC motor

The most common models in the AC network are MTF and MTKF electric motors, which have a wound rotor and a squirrel-cage rotor, respectively. And in metallurgical production, the model range consists of electric machines MTH and MTKH with the same design features. In practice, alternating voltage with a frequency of 50 and 60 Hz can be used to power both. The possibility of rotor rotation for them ranges from 600 to 1000 rpm for a supply electrical quantity with a frequency of 50 Hz. Or from 700 to 1200 at frequencies of 60Hz. Electric drives of mechanisms in most cases can have several speeds at once.

Direct current

DC electric motors are used to equip crane installations that require frequent switching over the course of an hour or an entire work shift. In addition, they allow you to adjust the frequency range over a fairly wide range. Of course, in our time, three-phase asynchronous machines can become closer to DC motors through the introduction of frequency conversion systems. Regulation is performed by either weakening the stator magnetic field or increasing the voltage of the rotor windings.

Rice. 2. DC motor example

Structurally, they are produced for power from 2 to 190 kW, depending on the value of the supply voltage, groups of excitation windings can have a serial or parallel connection. In this type of crane electric motors, control is carried out by changing the currents in the excitation winding.

Crane and metallurgical asynchronous electric motors of the 4MT series

The metallurgical industry is characterized by significant volumes of materials moved and the specific gravity of the metal. Therefore, crane electric motors of the MT series must provide the declared power, regardless of the rotation speed. The yoke of an electric machine is made with four or eight poles to transmit magnetic flux; the material for the magnetic core is cold-rolled steel. To insulate crane electric motors, polymer films, impregnated fabrics or paper are used as a dielectric.

Rice. 3. Crane-metallurgical electric motors

In electric drives of metallurgical cranes, greater reliability is built into the manufacturing stage - up to 0.98, while all others can have a coefficient of 0.96. The service life declared by the manufacturer must also be at least 20 years.

With wound rotor

Crane electric motors with a wound rotor are distinguished by the presence of a separate winding on the rotating part. The rotor coil is powered by a collector unit, which collects current and takes power through a sliding contact. However, the brush mechanism in them is the most wearable element; after the graphite contacts wear out, they must be replaced.

Rice. 4. Design of an electric motor with a wound rotor

This type of three-phase asynchronous electrical machines is characterized by smooth start-up and high load capacity. Due to this, they are installed on medium and heavy cranes that move heavy loads. Allows you to adjust the torque force on the shaft in three and four-step modes, proportionally increasing the impact power.

With squirrel-cage rotor

Structurally, the rotating part is a steel structure of cast or stacked type. Unlike the previous version, crane electric motors with a squirrel-cage rotor are lighter and have lower cost. However, the main disadvantage is the small torque created on the shaft, and this, in turn, leads to a lack of force. Therefore, squirrel-cage motors are installed on low-power crane installations designed to move light weight loads at low speed.

Specifications

Like any electrical installations, electrical machines are manufactured in accordance with the requirements and conditions in which they will be operated. When choosing a specific crane motor model, you are guided by its parameters. The main characteristics include:

Power consumption – characterizes the amount of consumed electrical energy required to operate the electric motor. May be expressed in kilowatts or kilovolt-amperes.
Efficiency – shows the ratio of useful work performed by an electric machine in relation to the electricity consumed from the network. In crane installations, this parameter can vary from 60 to 90%.
Rotation frequency - shows the number of shaft revolutions that it can make per unit of time. As a rule, the value per minute is used. For each model, the speed may vary, so the parameter will have a range value.
Shaft power – determines the force created by the crane electric motor directly on the working body.
Rated operating voltage - indicates the potential difference that must be supplied to the input of an electrical machine to set it in motion.
Weight and overall dimensions are the physical parameters required for installation in the overall crane structure.
The degree of dust and moisture protection is indicated by the Latin letters IP and two numbers indicating the possibility of particles penetrating into the housing.

Design of crane electric motors with phase and squirrel-cage rotor

The crane motor is usually supplied with:

crane brushes (spare set) – 6 pcs. (for electric motors with wound rotor MTF, MTH);
passport - 1 pc.;
instruction manual and technical description - 1 pc. (upon client's request).

Crane electric motors are produced with squirrel cage and wound rotor: MTF, MTH, MTKF, MTKH. According to the method of cooling and protection from external influences. engines are manufactured in a closed, i.e. blown design.

In a wound rotor motor, the main wear materials are electric brushes and brush holders for crane electric motors.

The crane motor with wound rotor (MTF, MTH) consists of:

hatch cover for removing dust from the brush unit,
bearing cap,
bearing shield,
inner bearing cover,
slip ring,
brush holder rod,
brush holder,
collector panel,
manifold hatch cover,
terminal box housing,
terminal box cover,
stator,
rotor,
eye bolt,
frame,
inner bearing cover,
bearing shield,
fan casing,
fan,
bearing,
bearing cap,
key,
crane motor shaft.

The motor for cranes with squirrel-cage rotor (MTKF, MTKH) does not have the following positions: 1, 5, 6, 7, 8, 9. To protect crane motors from corrosion, special paint and varnish and galvanic coatings are used. In terms of heat resistance, the insulating materials of the stator and rotor windings correspond to class H.

Safety measures, installation and preparation for operation of crane engines

When operating crane electric motors MTF, MTH, MTKF, MTKH, access to its rotating and live parts must be prevented. Do not turn on the engine if the commutator and fan casing is removed, with the terminal box open. An electric motor mounted for operation must be grounded. In case of carrying out preventive and routine maintenance, the crane electric motor must be disconnected from the power supply.

Before installing it, you need to clean all unpainted metal parts from anti-corrosion lubricant with a cloth soaked in kerosene or gasoline. Corrosion (if it appears) must be removed with sandpaper with a grain size of 50-N. After completely cleaning the corrosion areas, remove any remaining metal and emery dust. Before installing the crane motor, you need to measure the insulation resistance of the stator and rotor windings, which should not be less than 0.5 MOhm. Electric motors with lower insulation resistance must be dried. Drying can be carried out using short circuit current from low voltage or external heating. During drying, the permissible highest temperature of the winding should not exceed 145°C, subject to insulation class H. During drying, rapid heating of the electrical circuit must not be allowed. crane motor, since in this case intense steam may occur, which in turn has a harmful effect on the insulation. Drying can be considered complete if the insulation resistance (measured with a megohmmeter) is not less than 0.5 MOhm when hot. The electric motor can only be installed on a horizontal plane with its feet down, aligning the axis of the electric motor with the axis of the mechanism. The power cable must be supplied through rubber seals, if necessary, in a metal pipe, in a flexible metal hose or through a metal pipe.
