Classification of motor by ventilation cooling mode
Aug 02, 2018

1. An electric motor is cooled only by the radiation of the surface and the natural flow of air.

2.fan Cold type: The motor is driven by its own fans, supply cooling air to cool the motor surface or its internal.

3.He fan-cooled: The fan that supplies the cooling air is not driven by the motor itself, but by its independent drive.

4.Duct Ventilation Type: Cooling air is not directly from the outside of the motor into the motor or directly from the motor internal discharge, but through the pipe into or out of the motor, pipe ventilation fans can be fan-cooled or his fan-cooled.

5.Liquid Cooling: The motor is cooled with liquid.

6.closed cycle gas cooling: cooling Motor media circulation in the closed circuit including the motor and cooler, but the medium through the motor absorption of heat, after the cooler release heat. 

7.surface cooling and internal cooling: the cooling medium does not go through the internal motor conductor called the surface cooling, the cooling medium through the motor conductor interior is called internal cooling.
