Problems with micromotor lubrication:

※, the grease on the brush dries after the motor is left for a long time, so that the noise reduction effect cannot be achieved;

※, the brush is rusted and corroded after the motor is left for a long time, and the anti-rust and anti-corrosion function cannot be achieved

※, low voltage can not start, need external force to help the motor to start normally;

※, starting at low temperature, the current increases sharply, resulting in a large power consumption of the product;

※, the brush is oxidized and isolated, the contact is bad, and it needs external help to start normally;

※, bearing point oil is easy to dry, and the noise is obvious;

※, residual carbon appears in the brush;

※, the current can't drop, can not meet the product requirements;

※, the noise cannot be reduced, or there is abnormal sound, which cannot meet the product requirements;

※, the speed is too low;

※、Life requirement...

Solution:

※ Use fully synthetic base oil to ensure low volatility of grease and achieve noise reduction effect;

※, the base oil is added with metal deactivator to protect the brush from rust and corrosion;

※, Use base oil with low viscosity to reduce starting torque;

※, appropriately reduce the consistency of the grease and reduce the starting current;

※, while adding metal deactivator, use low viscosity and high consistency, small viscosity reduces starting torque, high consistency and noise reduction;

※, adjust the consistency of the grease according to the precision of the motor, and select the appropriate viscosity of the base oil according to the working conditions of the motor;

※, Appropriately reduce the soap content, while using synthetic base oil;

※ The current cannot drop because the viscosity of the grease is relatively large, and the viscosity of the base oil of the grease is appropriately reduced within the allowable range of noise.

※ The noise cannot be reduced mainly because the viscosity of the grease is relatively small, and the viscosity of the base oil of the grease is appropriately increased within the range allowed by the noise;

※ It can be known through the formula change that this is because the voltage is constant and the current increases, and the solution is the same as the current solution;

※, the use of fully synthetic, suitable viscosity of grease...
