The characteristics and basic components of miniature motors

Jun 25, 2019

Miniature motors have a small capacity, and motors with output powers typically below a few hundred watts require special motors for applications, performance, and environmental conditions. Full name micro-special motor, referred to as micro-motor. It is often used in control systems to realize the functions of detecting, solving, amplifying, executing or converting electromechanical signals or energy, or for transmitting mechanical loads, and also as the AC and DC power supply for equipment.


Micro motor characteristics


The micro motor is a reversible synchronous motor composed of a permanent magnet synchronous motor and a built-in speed reducer. It has the advantages of large torque, low noise, small size, light weight, convenient use, constant speed operation, etc. It can also be used with various gear boxes. Achieve the purpose of changing the output speed and torque.


The basic structure of a micro-motor is similar to that of an ordinary motor, including stators, rotors, armature windings, brushes, etc., but the structure is extremely compact. There are two common types: a combination of the above various micromotors; a combination of a micromotor and an electronic circuit. For example, a combination of a DC motor and a sensor, a combination of an X-direction and a Y-direction linear motor, and the like.


The outer structure is the same as the electromagnetic type. For example, the rotary products are made into a cylindrical shape, and the linear products are formed into a square shape, but the internal structure differs greatly depending on the working principle.
