【Robot Motor】Classification of micro geared DC motors


DC geared motor, that is, gear geared motor, is based on ordinary DC motor, plus supporting gear reducer. The function of the gear reducer is to provide a lower speed and a larger torque. At the same time, the different reduction ratios of the gearbox can provide different speeds and torques. This has greatly increased the use of DC motors in the automation industry. Geared motor refers to the integration of reducer and motor (motor). This type of integration is also commonly referred to as a gear motor or gear motor. It is usually integrated and assembled by a professional reducer manufacturer and supplied in complete sets. Geared motors are widely used in the steel industry, machinery industry, etc. The advantages of using geared motors are that they simplify the design and save space.
   There are several ways to classify micro geared DC motors:   1. Classification according to structure and working principle: According to the structure and working principle, the motor can be divided into asynchronous motor and synchronous motor. Synchronous motors can also be divided into permanent magnet synchronous motors, reluctance synchronous motors and hysteresis motors. Asynchronous motors can be divided into induction motors and AC commutator motors. Induction motors are further divided into three-phase asynchronous motors, single-phase asynchronous motors and shaded pole asynchronous motors.   2. Classification according to starting and running mode: Micro geared DC motors can be divided into capacitor starting motors, capacitor cup motors, capacitor starting running motors and split-phase motors according to the starting and operation modes.   3. Classification according to the working power supply of the motor: Micro geared DC motors can be divided into DC motors and AC motors.
