What types of micromotors are there?

Abstract: Micro-motor is a motor with small volume and capacity, and its output power is generally below several hundred watts, which has special requirements for use, performance and environmental conditions. It is often used in control systems to detect, calculate, amplify, execute or convert electromechanical signals or energy, or drive mechanical loads, or as AC and DC power supplies for equipment. Such as disk drives, photocopiers, CNC machine tools, robots, etc. , have applied micro-motors. Let's learn more about the types of micromotors and their application fields. Types of micromotors What kind of micromotors are used in what fields?

There are many kinds of micro and special motors, which can be roughly divided into 13 categories, such as DC motors, AC motors, self-rotating angle motors, stepping motors, rotary transformers, shaft angle encoders, AC and DC dual-purpose motors, tachometers, inductosyns, linear motors, piezoelectric motors, generator sets and other special motors.

trait

Motor is a reversible synchronous motor composed of permanent magnet synchronous motor and built-in gearbox, which has the advantages of large torque, low noise, small volume, light weight, convenient use and constant speed. It can also be matched with various gearboxes to change the output speed and torque.

Structural classification

Micro-special motors can be roughly divided into three types in structure:

Electromagnetic type

The basic composition is similar to that of ordinary motor, including stator, rotor, armature winding, brush and other parts, but the structure is particularly compact.

combined type

There are two common types: the combination of the above various micromotors; Combination of micromotor and electronic circuit. For example, the combination of DC motor and sensor, the combination of X-direction and Y-direction linear motor and so on.

Non-electromagnetic

The external structure is the same as electromagnetism, for example, the rotating product is made into a cylinder and the linear product is made into a square, but the internal structure is very different because of its different working principles.

applied range

Food machinery, textile machinery, medical equipment, intelligent doors and windows, monitor platform, advertising light box, household appliances, air conditioning blades, actuator control and other low-power constant-speed and high-torque equipment.

application area

Micro-special motors are mainly used in three fields: ① Driving occasions without special control requirements are used as the power source of sports mechanical loads. ② Audio-visual equipment. For example, in a video cassette recorder, the micromotor is not only a key component of the drum assembly, but also an important component for capstan drive, automatic loading of tapes and cassette tapes, and tape tension control. ③ Office automation equipment, computer peripheral equipment and industrial automation equipment. Such as disk drives, photocopiers, CNC machine tools, robots, etc. , have applied micro-motors.
