Why doesn't the mixer turn? Where is the problem? What maintenance methods should we have when we use juicers and mixers every day? Most of the juicers and blenders do not work because they are not maintained in daily use, and the motor does not rotate due to large losses. There are also two types of problems on the motor: 1. A partial short circuit in the motor can also cause this type of failure. This mainly refers to the short circuit of the rotor and stator windings of the motor or the short circuit of the commutator. In addition, the continuous working time of the juicer and blender will also cause the motor temperature to rise too high, especially the lower power or poor quality motor heat is more serious, so each use time is generally not more than 1 minute . 2. Most of the motor's operating temperature rises too high, which causes the thermostat switch ST to act, causing automatic shutdown. The specific reasons are mostly motor or operational problems. The defective thermostat switch ST itself can also cause this kind of failure, but it is usually rare. So how should we maintain the juicer and blender every day? First of all, we should pay attention to daily cleaning in daily use. On the rotating motor, capable users can disassemble it to add a little lubricating oil after hearing some abnormal sounds. Adding lubricating oil is very important for some rotating appliances. For example, electric fans should be cleaned every day and add lubricating oil. This will extend the life of home appliances.
