Electric Motor Air Cooling System

Ambient air density.

Electric motor air cooling system.

Below is several factors affecting rate of heat transfer for electric motor cooling 1. This is the most common method for cooling electric motors you will find in the industry. In this cooling method the electric motor is essentially cooled by free convection current from the air. The cooling system of electric motor or generator consists of water tanks fans pumps thermostats thermostats compensating kettle the engine is a machine that converts other forms of mechanical energy from the cylinder block to the water liner in the cylinder head some cars also have a water temperature sensor plug.

Air cooling uses the principle of convection to transfer heat away from the battery pack. This factor is important for motor cooling if the ambient air density is good it will effected for reduction of heat transfer from the electric motor. Ic 418 with this cooling method the motor is cooled by an air. This is protected by a perforated cowl which also protects inquisitive fingers from the fan blades.

Using fins to cool the electric car battery has fallen out of favor since the additional weight of the fins outweighs the cooling benefits. Ic 411 in this cooling method the motor is cooled by a fan mounted on the motor shaft. The different methods of cooling rotating machines are classified in the standards iec 34 6 and as 1359 21.

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. For ac induction motors cooling air is usually circulated internally and externally by one or more fans mounted on the rotor shaft. 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.

As air runs over the surface it will carry away the heat emitted by the pack.
