Using fins to cool the electric car battery has fallen out of favor since the additional weight of the fins outweighs the cooling benefits.
Electric motor air cooling system.
Ic 418 with this cooling method the motor is cooled by an air.
To allow for operation of the machine in either direction of rotation fans are usually of the bi directional type and made of a strong plastic material aluminum.
Another common method for keeping electric motors cool is forced draught air cooling.
Industrial motors often have an integral fan mounted on the rear of the output shaft so that it spins at the same rate as the driven load.
Ambient air density.
Cooling is necessary to continuously transfer the heat to a cooling medium such as the air.
Low voltage motors totally enclosed ip44 and higher ic410 tenv totally enclosed naturally ventilated no fan ic411 tefc totally enclosed fan cooled own fan ventilated ic416 tefv totally enclosed force ventilated ventilated with independent fan ic418 teao totally enclosed air over no fan motor in air stream water in out ic71w jacket water cooled.
As air runs over the surface it will carry away the heat emitted by the pack.
In this cooling method the electric motor is essentially cooled by free convection current from the air.
Air cooling uses the principle of convection to transfer heat away from the battery pack.
Electric motor cooling systems.
This is protected by a perforated cowl which also protects inquisitive fingers from the fan blades.
The different methods of cooling rotating machines are classified in the standards iec 34 6 and as 1359 21.
Ic 411 in this cooling method the motor is cooled by a fan mounted on the motor shaft.
This is the most common method for cooling electric motors you will find in the industry.
How to control temperature for electric motor the best method is with motor cooling system basically heat generated during motor running will be transferred to the ambient air surrounding.
For ac induction motors cooling air is usually circulated internally and externally by one or more fans mounted on the rotor shaft.
