The key points for maintaining the motor of a coffee grinder mainly include the following aspects
Circuit inspection: Regularly check the circuit condition of the bean grinder to prevent problems such as aging, damage or rodent gnawing of wires. This is an important step to ensure the normal operation of the motor and prevent safety accidents.
Voltage and current monitoring: Although this point leans more towards the usage norms of the motor, it is also important to understand and monitor whether the voltage and current used by the motor are within the normal range. Both excessively high and low voltages and currents may cause damage to the motor.
Abnormal noise and high temperature handling: If the motor experiences abnormal noise or high temperature (exceeding the normal operating temperature) during operation, it should be stopped immediately for inspection. This might be a sign that the internal parts of the motor are damaged or overloaded, and it needs to be dealt with promptly to prevent further damage.
Lubrication and maintenance: If the bearings or other rotating parts of the motor need lubrication, an appropriate amount of lubricating oil or grease should be added regularly. This helps to reduce wear and tear and extend the lifespan of the motor.
Dust prevention and cleaning: Keep the motor and its surrounding environment clean to prevent dust, coffee grounds and other debris from entering the motor interior. This can be achieved by regularly cleaning the motor housing and vents.
