Problems with micromotor lubrication:

※、After the motor is placed for a long time, the grease on the brush will dry out, so that the noise reduction effect cannot be achieved;

※、After the motor is installed for a long time, the brush is rusted and corroded, 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;

※、When 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 poor, and it needs external help to start normally;

※、Bearing oil is easy to dry, and the noise is obvious;

※、There is carbon residue at the brush;

※、The current cannot be lowered, and the product requirements cannot be met;

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

※、Too low speed;

※、Life requirements...  

Solution:

※、Use fully synthetic base oil to ensure low oil volatilization and achieve noise reduction effect;

※、The base oil is added with metal passivator 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;

※、When adding metal passivation agent, it adopts low viscosity and high consistency, low viscosity reduces starting torque, and high consistency reduces noise;

※、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 soap content and use synthetic base oil;

※、The main reason that the current cannot be lowered is because the viscosity of the grease is relatively large, and the viscosity of the base oil of the grease should be 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 should be appropriately increased within the allowable range of noise;

※、By changing the formula, we can know that this is because the voltage does not change and the current increases, and the solution is the same as the current solution;

※、Using fully synthetic, suitable viscosity grease...
