How To Keep Electric Motors Cool

Electric motors are used in machines and processes all around us.

How to keep electric motors cool.

With the efficiency of brushless motors and higher lipo battery capacities run times in the 20 minute range aren t uncommon. After moisture they are the greatest contributor to bearing and winding failures. These are designed to keep the air flow close to the surface of the motor along its entire length thus improving the cooling and self cleaning of the ribs. Insulation s major enemy is heat so it s important to be sure to keep the motor within temperature limits.

With this esc motor in it it to shuts down alot the motor gets really hot not sure of temp it has the 90t spur i have a 22t spur in it now if i loosen the slipper it gets so hot it accually melted the gearbox. An air gap is usually left between the ribs and the fan cover for this purpose. A variation of this is found on many industrial motors which have a finned cover over much of their body length. Another common method for keeping electric motors cool is forced draught air cooling.

An electric motor s insulation system separates electrical components from each other preventing short circuits and thus winding burnout and failure. But during extended runs heat build up can affect your motor s performance or at worst cause total system failure. I have a fan on the motor but doesn t seem to cool it down enough. With summer quickly approaching we give you nine ways to keep your engine cool so you can get the best performance out of your vehicle.

It depends on the clock. Electric motors are often selected based upon a particular work or load requirement. By jim bryan electrical apparatus service association easa the effects of excessive temperature on motor performance are notorious. 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.

Protection starts at the source. They use only premium materials and electric motors. Critical motors in nuclear power plants have an administratively specified restart waiting time. Regardless of the application managing heat dissipation is a common theme.

You can find them in factories automobiles airplanes robots and even your favorite dvd vending machine. A cool motor is a happy motor unless it isn t being run. Home technical articles cooling and ventilation of electric motors ic. You keep restarting the motor as soon as the overloads let you and you cook the motor to death.

It doesn t depend on the cooling of the overload. Understanding the source of increased temperature is key to correcting the problem and improving.
