Electric Motor Air Cooling System

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.

Electric motor air cooling system.

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. 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. 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. Cooling is necessary to continuously transfer the heat to a cooling medium such as the air.

For ac induction motors cooling air is usually circulated internally and externally by one or more fans mounted on the rotor shaft. This is the most common method for cooling electric motors you will find in the industry. Ambient air density. Ic 418 with this cooling method the motor is cooled by an air.

As air runs over the surface it will carry away the heat emitted by the pack. Below is several factors affecting rate of heat transfer for electric motor cooling 1. Another common method for keeping electric motors cool is forced draught air cooling. Air cooling uses the principle of convection to transfer heat away from the battery pack.

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. In this cooling method the electric motor is essentially cooled by free convection current from the air. This is protected by a perforated cowl which also protects inquisitive fingers from the fan blades. Electric motor cooling systems.

The different methods of cooling rotating machines are classified in the standards iec 34 6 and as 1359 21.
