Miniature geared motors are small in size and capacity, and require a special motor for motors and applications, performance and environmental conditions with output powers typically below a few hundred watts. Full name micro special motor, referred to as micro motor. Commonly used in control systems to achieve the function of detecting, solving, amplifying, executing or converting electromechanical signals or energy, or for transmitting mechanical loads.
Micromotors can be roughly classified into three categories in structure: 1 electromagnetic. The basic composition is similar to that of a normal motor, including stators, rotors, armature windings, brushes, etc., but the structure is extremely compact. 2 combination. 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. 3 non-electromagnetic. 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.
The performance of various types of micro-motors varies greatly, and its performance parameters are difficult to clarify. Generally speaking, the driving machinery is focused on the force and energy indicators during operation and starting; the power supply is used to consider the output power, waveform and stability; the control micromotor is biased towards static and dynamic characteristic parameters. The characteristic parameters of the first two types of motors are similar to those of ordinary motors. Only the control micromotor has its unique characteristic parameters.
