Note:
- The values colored “Red” indicate that the gearbox and the DC motor are running in the same direction, and the other values are in the opposite direction.
- When it is desired to reduce the speed further than the gear ratio in the table above, an intermediate speed reducer with a gear ratio of 10 can be installed between the motor and the gearbox.

Tips: Difference between gear motor and VFD
The VFD changes the routine power supply into AC power supply of various frequencies, so as to realize the variable speed operation of the motor. In this process, the control circuit completes the control of the main circuit, the rectification circuit transforms the AC into DC, the DC intermediate circuit carries out smoothing filtering to the output of the rectification circuit, the inverter circuit transforms the DC into AC. As for the VFD that requires large amount of calculation, such as the vector controlled inverter, a CPU for torque calculation and some corresponding circuits may also be required. Frequency control is realized by changing the frequency of power supply for motor stator winding.
Gear motor is a power transmission mechanism that can be used for both high torque and common speed applications such as conveyer belt, mixer, windlass, clapper and automation special machine etc.. Moreover, with the development of industry and the automation of factories, demand for gear motor keeps on increasing. There are many ways to decelerate, but the most commonly used method is to decelerate with gears as it can reduce the space and costs.
