YVP系列变频调速电机说明: 

  一、变频电机概述  

 

   变频调速电机是 一种变更供电频率,达到电机调速的目的,变频调速电机简称变频电机,是变频器驱动的电动机的统称。实际上为变频器设计的电机为变频专用电机,变频电机可以 在变频器的驱动下实现不同的转速与扭矩,以适应负载的需求变化。变频电机由传统的鼠笼式电动机发展而来,变频电机把传统的电机风机改为独立出来的风机,并 且提高了电机绕组的绝缘性能。

    YVP系列变频调速电机必须与变频器配合使用。目前国际上普遍采用变频调速,因为变频调速有以下优点:
1、效率高、节能显著;
2、调速平滑能在5-100HZ范围内无级调速;                                    

    3、低频起动时力矩参负载冲击小;
4、起动电流小,不加附加起动设备;
5、体积小、重量轻、安装尺寸和Y系列相同;

    6、在风罩内装有轴流风机,在各种转速下,均有良好的冷却效果;
7、应用范围广,在50HZ以下可作恒转矩运行,在50HZ以上可作恒功率运行;
8、较电磁调速电机节电结构简单,使用可靠,维修方便。

  YVP系列变频调速电机依据的原理(公式):n=60f/p由上述公式看出,当电机极数(p)一定时,频率变更,电机每分钟转速(n)必然变更(成正比),通过变频器一般频率变更在10-60HZ(赫兹)之间,但也可延伸至5-100HZ。

二、YVP系列变频调速电机使用条件
1、环境温度不超过-15℃+40℃
2、海拔不超过1000m
3、电机防护等级IP44
4、电源电压380(220)V±10%      频率50(60)HZ±2%
三、YVP系列变频调速电机主要性能指标
1、调频范围:550HZ恒转矩 50100HZ恒功率
2、工作制:连续(SI)
3、接法3KW及以下用Y接法,但变频器输出为三相220V时可改为△,4KW及以上为△接
4、起动转矩125%
5、绝缘等级:F级,电机内部最高耐温为>110℃
