Factors such as reduction ratio, working conditions, and control methods may cause a decrease in motor efficiency, so it is necessary to choose the appropriate motor, reduction ratio, power, etc. based on the operating conditions.

What is the function of a deceleration motor? The deceleration motor has two main functions. Firstly, they obtain the torque generated by the power source (input) and multiply it. Secondly, as the name suggests, a deceleration motor reduces the input speed to achieve the correct output speed.

How can a deceleration motor increase torque while reducing speed? The output gear of the reduction motor has more teeth than the input gear.

Therefore, although the output gear may rotate slower, thereby reducing the input speed, the torque increases.

In short, they use output power to increase torque while reducing speed

There are various shapes and sizes of reduction motors, but some common reducers are gearboxes, which is the reason for the decrease in efficiency of micro reduction motors. The main reason for the decrease in efficiency of micro reduction motors is the increase in various losses, such as copper loss, iron loss, mechanical loss, etc. Large copper losses in micro reduction motors

The type of motor itself also has different efficiency characteristics. DC brushless motors are usually more efficient than brushed motors because brushless motors do not have friction losses between brushes and commutators.
