WHAT IS THE WORKING PRINCIPLE OF THE CRANE MOTOR YZR,YZ? HOW TO CHOOSE? CHINA FACTORY SEALOCEAN

The working principle of the hoisting motor is the same as the working principle of the traditional motor. It can be understood as the characterization of the phenomenon of the interaction and induction of electric energy and magnetic energy. related performance.

1. The working principle of the lifting motor can be simply understood as electromagnetic induction. In simple terms, the hoisting motor generates a magnetic field after being energized, and the rotor cuts the magnetic field lines to make it rotate. The starting point memory is generally more of a wound motor, and the speed is adjusted by a resistor in series with the rotor. After the inverter is connected, the rotor should be replaced and the number of stator coil gates should be increased. (Otherwise it will be very hot.) 2. Hoisting motors and metallurgical variable frequency speed-regulating motors are squirrel-cage rotor motors. It combines the advantages of traditional hoisting and metallurgical motors with the advantages of variable frequency motors, so that the motor can not only meet the needs of frequency starting, braking, overload, reverse rotation, overspeed, shock and vibration, but also meet the needs of the workplace to run under the control of frequency converters To meet the needs of soft start, four-quadrant operation, etc., to reduce the impact on the equipment and save energy. Click to read: What kind of brakes are generally used for hoisting motors?

3. The rated voltage of the hoisting motor is 380 V, the rated frequency is 50 Hz, and the reference working system is S3-40%. The motor adopts forced ventilation cooling method, so that the motor has a good heat dissipation effect in a wide frequency range. The insulation level and protection level of the motor are the same as those of the YZ and YZR motors. The installation dimension of the motor is the same as that of the YZ and YZR motors, which ensures good interchangeability. The motor shape adopts a new design, which is beautiful and generous. Motors above H160 have independently powered cooling fans to meet the needs of ventilation and heat dissipation when working in low frequency bands. The basic series has no encoders, overspeed switches, etc.

4. The working principle of the crane is as follows:

(1) The working principle of the crane is to keep the distance with the pulley lever. The crane consists of a drive device, a working mechanism, a pick-up device, a control system and a metal structure. Through the operation of the control system, the driving device converts the input power energy into mechanical energy, transmits the force and movement speed to the picking device, connects the transported materials with the crane, and completes the material processing tasks through the working mechanism alone or in combination. The movable metal structure connects the components as a whole, carrying the crane's own weight and lifting weight.

(2) The working principle of the crane is to use the lever principle, the balance weight and the suspended weight are in a balanced state through the crane, and then the fixed pulley block is used to slow down and increase the torque by winding, so as to achieve the purpose of weightlifting.

1. When choosing a crane motor, you should understand the relevant parameters of the crane in order to formulate general selection criteria for the crane's performance requirements such as starting, braking, speed regulation, load, torque, and synchronization. Click to read: What is a crane motor? What are its characteristics?

2. Generally speaking, the selection of hoisting motors must take into account factors such as model, model, rated speed, rated voltage, rated power, etc., such as the manufacturer of the motor, after-sales service maintenance support, service life, corrosion resistance and other special properties.

3. Secondly, when choosing a motor suitable for a crane, it should be considered whether the shape, structure and weight of the motor are suitable for the crane, and whether the motor can adapt to the environmental conditions, working system and workload of the crane.

One of the typical advantages of a hoisting motor as a motor that can be frequently used in lifting occasions is that it has excellent mechanical strength. In order to make the crane meet the needs of the work, it is necessary to choose a suitable hoisting motor. The selection of the hoisting motor not only needs to be combined with the actual needs, but also with the performance parameters of the motor.
