How Can We Help?
What is a Geared Motor ?
A gear motor is a mechanical component that combines a gearbox with an electric motor. The electric motor converts externally input electrical energy into kinetic energy. This kinetic energy is then regulated by an internal gear reduction mechanism within the gearbox, reducing the motor’s output speed while increasing its torque.
Types of Geared Motor
Based on the gearbox design, we can broadly categorize our DC geared motors into the following two types:
- Square DC Geared Motor
- Round DC Geared Motor

Frequently Asked Questions
Q: How to calculate the output torque of a geared motor?
A: Determine the motor’s output power and speed, then use the formula to calculate the motor’s output torque:
𝑇motor = 𝑃motor × 60 / (2𝜋 × 𝑁motor). Determine the gear ratio and then use the formula to calculate the geared motor’s output torque:
𝑇output = 𝑇motor × 𝑖.
Q: How to calculate the output speed of a geared motor?
A: Determine the motor’s original speed and the gear ratio, then use the formula to calculate the geared motor’s output speed:
𝑁output = 𝑁motor / 𝑖.
Q: What is the typical lifespan of SGMADA geared motors?
A: SGMADA offers micro DC geared motors with lifespans ranging from a few hundred to several thousand hours.
Q: How to calculate the efficiency of a gearbox?
A: Gearbox efficiency can be calculated by the ratio of output power to input power using the formula:
Efficiency = (𝑃output / 𝑃input) × 100%. Efficiency is typically affected by gearbox design, lubrication, and load conditions.
Q: Does SGMADA offer customized DC geared motor services?
A: Yes, SGMADA offers customized DC geared motor services to meet specific customer requirements and applications.
