  • Working system

La serie YZR-H de elevación marina y motores asíncronos metalúrgicos trifásicos tienen las características de alta capacidad de sobrecarga y alta resistencia mecánica, especialmente adecuado para conducir varios tipos de maquinaria de elevación y metalúrgica u otros equipos similares. La elevación marina de la serie YZR-H y el motor asíncrono trifásico metalúrgico es el motor del rotor. Los motores de la serie YZR-H se sujetan con escobillas con el último diseño de muelles de voltaje constante, y la presión entre el anillo colector y el cepillo sigue siendo la misma cuando el cepillo se desgasta en funcionamiento.

El motor puede funcionar correctamente bajo las siguientes condiciones:

temperatura ambiente no superior a la temperatura ambiente 40 ° C (para uso ambiental general);

No más de 1000m sobre el nivel del mar;

vibración mecánica regular y choque;

Poder: 0.75~100kW

Voltaje:380V

Frecuencia:50Hz

Protection class: IP44

Insulation: F

Temperatura ambiente: ≤40℃

Palabras clave: YZR-H series motor, winding rotor motor, marine motor, motor trifásico, motor asíncrono, motor asíncrono trifásico, marine lifting motor, metallurgy motor

The working systems of this series of motors are divided into eight types: S2, S3, S4, S5, S6, S7, S8, S9

S340% (i.e. working at S3, 40% load duration, 10 minutes per cycle). The following are several of the most commonly used working systems for this series of motors.

  1. Short working hours (S3)

Operating at a given time under a constant load, the motor is not sufficiently thermally stable during that time, and then downtime and energy loss are sufficient for the difference between the temperature of the motor and the cooling medium to be within 2K.

  1. Intermittent Work (S3)

Run by a list of the same working cycles, each including a constant load run time and a downtime and outage time. In this type of work, the start current per cycle does not have a significant effect on heating.

  1. Includes startup intermittent work (S4)

Run by a list of the same working cycles, each including a period of startup time with a significant impact on heating, a period of constant load run time, and a period of downtime and outage time.

  1. Intermittent cycle working including electric braking (S5)

Run by a list of the same working cycles, each including a start time, a constant load run time, an electric brake time, and a downtime and outage time.
