There are many aspects to the parameters of a planetary gearbox, and many people don't know how to choose when choosing one. Next, CSG will introduce the inertia matching and optimal reduction ratio of planetary reducers.

Inertia matching of planetary reducers: Rotational inertia is a major parameter of servo planetary reducers, and the calculation formula for rotational inertia varies depending on the structure. When calculating the moment of inertia of load transmission on the reducer shaft, the reciprocal of the transmission ratio should be reduced to 1/i square times. When the moment of inertia of the load is equal to the moment of inertia of the electric motor, this is inertia matching.
The optimal reduction ratio for servo gearboxes: Servo motors typically have high speed and low torque output, while
The load generally requires low-speed high torque, so a planetary reducer is usually connected between the servo motor and the load. Its function is to reduce the speed, increase the torque, and achieve the matching of motor speed and torque with the load. The ratio of the speed of the reducer to the load speed is called the reduction ratio. The so-called optimal reduction ratio refers to the highest rate of power change on the load side.
