Efficiency Brushless motors are generally more efficient than brushed motors.Because brushless motors do not have the frictional losses associated with brushes and commutators, electrical energy can be more effectively converted into mechanical energy.Generally speaking, brushless motors The efficiency can reach 85%-90%, while the efficiency of a brushed motor is approximately 70%-80%. Lifespan The brushes and commutator of a brushed motor will gradually wear out with long-term use, which will shorten the motor's lifespan.The lifespan of a typical brushed motor typically ranges from a few hundred to several thousand hours.And the brushless motor Without these consumable parts, the machine's lifespan can reach tens of thousands of hours, greatly increasing the equipment's service life. Noise When a brushed motor is running, the friction between the brushes and the commutator produces a significant amount of noise.In comparison, brushless motors produce very little noise when running, making them more suitable for situations where noise requirements are high, such as Household electronic products, precision instruments, etc. Control precision Brushless motors, due to their use of electronic commutation and precise position sensors, have a higher level of control accuracy.It can achieve more precise speed control and position control, which is crucial in some applications where precision is required Widely used in four areas of industry automation.
