结构特点 Structural characteristics

YVF2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，安装尺寸和功率等级与JHM系列电机一致，互换性、适用性强。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 YVF2 series motors with high strengh cast iron structure, have the characteristics of high reliability, wide speed range, high precision, high interchangeability and applicability with JHM series motors because of their same power grade and mounting imension. The Y2VP series motors have independent cooling fan to ensure good cooling effect under different speed.
