因独立风机电机的长度增加ΔL

Motor length increase by ΔL because of cool fan



结构特点  Structural characteristics               

  YVF3 系列电动机采用高强度铸铁结构,具有可靠性高、调速范围宽、精度高等特点,装有独立的冷却风机,保证电机在不同转速下均有良好的冷却效果。
       The Y2VF series motors with high strengh cast iron structure, have the characteristics of high reliability, wide speed range, high precision. The Y2VP series motors have independent cooling fan to ensure good cooling effect under different speed.
