Use and Maintenance of Brushless DC Motors
Brushless DC motors are nowadays widely used in many applications, due to their special characteristics and improved performances. In order to make sure that the motors keep performing as expected, a certain level of maintenance is usually required. This article provides an overview of the necessary steps to adhere to if you want to ensure a good and proper use of brushless DC motors.
First and foremost, it should be noted that brushless DC motors require a much cleaner electric environment than other types of motors, due to the absence of brushes, which are usually responsible for switching the power and generating electrical noise. This means that brushless DC motors ought to be installed in a clean and dry area away from the influence of environmental contaminants like dust, grease and liquids. Additionally, it is also important to pay attention to other sources of electromagnetic interference, such as all types of motors, as these can interfere with the performance of the brushless DC motor.
In order to have an optimal performance, brushless DC motors should be regularly lubricated and inspected. To lubricate the motor you should use a lubricant that is specifically indicated for the motor’s type. Regular lubrication will help to prevent the motor from corrosion, heat related damage and other potential damages due to insufficient lubrication. Besides the regular lubrication, it is also recommended to perform an inspection on at least a yearly basis if the motor is used extensively.
When it comes to maintaining a brushless DC motor, it is important to pay attention to the alignment and balance of the rotor. In order to keep the performance of the motor optimal, the rotor should be perfectly aligned. Any irregularities on the rotor can lead to overheating and the motor will eventually overheat if the imperfections are not addressed. Additionally, it is also important to pay attention to the balance of the rotor on a periodic basis, as an unbalanced rotor can lead to an increase in vibration, decreased efficiency and even system failure.
Finally, it is a good idea to also make sure that any cable wires used in the motor are of suitable quality. Good cables will help to reduce the environmental noise and provide a proper electrical connection between the motor and power or control unit. Cables that are of inferior quality can lead to electromagnetic interference and disruptive power or current flow.
In conclusion, brushless DC motors require a certain level of maintenance in order to keep their performances at a high level and prevent potential damages due to improper use or insufficient lubrication. It is important to make sure that the motor is properly lubricated and inspected, that the rotor is well aligned and balanced, and that the cable wires used in the motor are of a suitable quality. Paying attention to these points will ensure the proper operation of the brushless DC motor.
