Micro motor in the structure can be roughly divided into three categories:
Electromagnetic
Basic composition is similar to ordinary motors, including the stator, rotor, armature windings, brushes and other components, but the structure of the extraordinarily compact.
Combination
There are two common types: the combination of the various micro-motors mentioned above; micro-motors and electronic circuits. For example, the combination of DC motors and sensors, the combination of X-direction and Y-direction linear motors.
Non-electromagnetic
The shape and structure of the same electromagnetic, such as rotary products made into a cylindrical, linear products made into a square, but the internal structure due to its working principle is very different. Food machinery, textile machinery, medical equipment, intelligent doors and windows, monitor panels, advertising light boxes, household appliances, heating and air conditioning fan page, actuator control and other small power constant speed and large torque equipment.
Applications
Microtronic motors are mainly used in 3 areas: ① No special control requirements for driving occasions as a power source for the movement of mechanical loads. ②Audio-visual equipment. For example, in the cassette recorder, micro motors are both the key components of the drum assembly, but also its leading axis drive, receiving and supplying tape and tape cartridges for automatic loading, as well as an important component of the tape tension control. ③ Office automation equipment, computer peripherals and industrial automation equipment. Such as disk drives, photocopiers, CNC machine tools, robots and other applications of micro-motors.
