I. Liquids and solids
Second, liquid and liquid.
Brief introduction of motor: 1, the structure of three-phase asynchronous motor consists of stator, rotor and other accessories; 2.DC motor adopts octagonal fully laminated structure and series excitation winding, which is suitable for automatic control technology requiring forward and reverse rotation of motor.
That is, we often say AC motors and DC motors. First of all, choose the motor type according to the physical properties, weight and specific gravity of the materials you stir, and pay attention to the amount of stirring once to choose the power of the motor. Use less electricity and choose more electricity.

Classification of uses According to uses, motors can be divided into drive motors and control motors. The driving motor is divided into electric tools (including drilling, grinding, polishing, slotting, cutting, reaming and other tools) and household appliances (including washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, DVD players, vacuum cleaners, cameras, hair dryers, electric shavers and so on). ) and other general small mechanical equipment (including all kinds of small machine tools, small machinery, medical instruments and electronic instruments). Control motors are divided into stepper motors and servo motors.
