RS-390 DC Motor Precision Materials
|
Rolling bearings have smaller friction coefficients and higher rotational accuracy, better operating stability and life, and can withstand higher rotational speeds and impact loads.Ball bearings help reduce energy loss and extend the life of the motor by reducing excess heat generated by friction between moving parts. |

 |
The RS-390 12 volt dc electric motor uses NdFeB magnets, which are reliably stable and will not lead to magnetic degradation or failure of the micromotor over long periods of time.In addition, NdFeB magnets have high resistance to oxidation and oxidation, which can resist the effects of the external environment on the performance of the 390 motor.
