Micro gear motor is also called the micro gear box, what are the factors that affect its specific? Here is a simple list for everyone common four:

1, the influence of the periodic load change amplitude cyclic load range, the greater the aluminum shell motor speed leave oscillation of synchronous speed, the greater the cage at this time in the winding current; The smaller the load range, miniature aluminum shell reducer dynamic efficiency are the higher accordingly.

2, the moment of inertia moment of inertia is larger, the influence of aluminum shell micro motor rotating oscillation under cyclic load and the squirrel-cage winding current is small, the appropriate increase the moment of inertia of miniature aluminum shell reducer J to improve the dynamic stability of miniature aluminum shell reducer is beneficial, but J increases too much even tiny aluminum shell reducer unstable operation. Increased moment of inertia can improve the aluminum shell under cyclic load of micro motor dynamic efficiency.

3, the influence of applied voltage, the higher the voltage, the miniature aluminum shell reducer speed under cyclic load fluctuation will be smaller, the squirrel-cage winding current is smaller, the aluminum shell stability of micro motor, the better. Voltage drop can cause tiny aluminum shell reducer under cyclic load efficiency is reduced.

4, the influence of stator resistance, micro motor stator resistance is aluminum shell under cyclic load to miniature of the aluminum shell reducer had a greater influence on the dynamic efficiency of a parameter. The stator resistance, the greater the aluminum shell under cyclic load miniature motor speed oscillation and the greater the current in the squirrel-cage winding, and vice versa. Stator resistance decreased when the load changes caused by the transition process of the intensity decreased, the transition process is short. Reduce the stator resistance value is helpful to improve micro mechanical and electrical stability of the reduction gear box, aluminum shell can also reduce the miniature aluminum shell reducer additional loss, improve micro aluminum shell reducer under cyclic load of dynamic efficiency.
