Brushless motors are essentially maintenance-free because they don't have brushes that wear down over time. Their primary maintenance involves ensuring the motor shafts are clean and lubricated to prevent overheating. Otherwise, they are more durable and require less upkeep than their brushed counterparts.
Understanding the features and maintenance requirements of brushed and brushless motors can greatly assist in making an informed decision. The answers to these common queries should provide a better understanding of what each type of motor offers and their best field of application.
