电机采用强迫通风冷却方式，使得电机在宽广的频率范围内均有良好的散热效果。电机绝缘等级及防护等级的设置与YZ、YZR电机相同。电机安装尺寸与YZ、YZR电机相同，从而保证了良好的互换性。电动机外形采用新的设计，美观大方。H160以上电机带独立供电的冷却风机，以满足低频段运行时通风散热的要求。基本系列不带编码器、超速开关等（适合于开关控制），编码器、超速开关、制动器等可按用户需求加装。是冶金、起重机械的理想动力，产品广泛用于冶金、起重、水利电力等行业。The motor adopts forced ventilation cooling mode, which makes the motor have good heat dissipation effect in a wide frequency range. The setting of motor insulation grade and protection grade is the same as that of YZ and YZR motors. The motor installation dimension is the same as that of YZ and YZR motors, thus ensuring good interchangeability. The appearance of the motor adopts a new design, which is beautiful and generous. Motors above H160 are equipped with independent power supply cooling fans to meet the requirements of ventilation and heat dissipation during low-frequency operation. The basic series does not have encoder, overspeed switch, etc. (suitable for switch control), and the encoder, overspeed switch, brake, etc. can be installed according to user requirements. It is the ideal power for metallurgy and hoisting machinery. Its products are widely used in metallurgy, hoisting, water conservancy and electric power industries.
