Brushless DC Motor Advantages And Disadvantages


BLDC motor means brushless dc motor, the working principle of this kind of motor is different from brushed type. Main feature is that the electronic commutation replaces traditional mechanical commutation, more reliable performance than brushed dc motor, no wear or tear, super lower failure rate and lifetime is six times longer than dc brush motor. Invotations of development direction of electric vehicles. Brushless dc motor has a such small no-load current. High efficiency and small dimensions are BLDC’s advantages.

For the distantage of brushless dc motor is that when it is working at low speed (beginning of start working), there will be slight vibration. When speed increasing and commutation frequency increased, the vibration phenomenon disappeared. Generally the brushless dc motor price is higher than brushed type. And sometime the BLDC motor need a controller.

Because everything has a natural frequency of vibration, it is easy to creating resonances. If the vibration frequency of the brushless motor is the same as or close to the vibration frequency of the frame or plastic parts, it is easy to form a resonance phenomenon, but it can be resonated by adjustment. This phenomenon is minimized. Therefore, a common phenomenon is that an electric car driven by a brushless motor sometimes makes a harsh sound.

Still Can’t Find Ideal Motors?


The electrical parameters of the motor can be adjusted. For example, the two main factors determining the vibration force: the size of the pager motor eccentric mass and the speed requirement. , voltage, current can be adjusted according to customer needs. Some encapsulated vibration motors adding terminals connectors, which are our customized products according to different customers. You can also contact us in the bottom contact form to ask for your needs.

If you want a custom lead wire connection of the  water resistant vibration motors. Such as alternate lead wire length & strip lengths, with a connector (e.g. Molex, JST). You can contact us from the footer form, tell us your need. Any problems will be taken seriously and will be answered professionally, so pls do not hesitate to contact us by the footer form.
