The heating of the working motor of the small mixer is a normal phenomenon. Under normal conditions, the heat generated by the motor will be distributed through the motor shell in time, so as to ensure the stable operating temperature inside the motor and protect the internal parts of the motor from damage.
There are two reasons for the serious heating of the motor after the use of the small mixer: first, the heat of the motor winding is too late to be dissipated through the shell; 2、 The heat dissipation capacity of motor shell is poor. These two factors will cause excessive heat of the motor of the small mixer and cause the motor to burn out.
The root causes of motor overheating caused by the above two factors are:
1、 The motor winding of the small mixer produces too much heat. The fundamental problem is that the motor conductor is not a pure copper conductor. The pure copper conductor has strong conductivity and low resistance, so it produces less heat. If the conductor of other materials has high resistance, the motor produces more heat when working;
2、 The reason for the poor heat dissipation capacity of the motor shell after the operation of the small mixer is that the shell is not made of pure aluminum. Alloy aluminum has light weight and strong heat dissipation capacity. Other materials are used as motor shell, so the heat dissipation capacity is not as good as aluminum.
To sum up, the above two factors are caused by small mixer manufacturers to save production costs.
