Gear motors come in many different sizes with a range of power outputs, but they are all usually powered by electricity and have a drive shaft that engages with a rotating gear to exert force. Even something as basic as the wipers on the windshield of a car has a very small gear motor that turns the gears of the wiper arms and allows them to move back and forth. Of course, gear motors can also be much larger than this and they can have enough power to move a large industrial conveyor belt or lift a pulley with a heavy load.

Applications of Gear Motors
The motor is encased in a unit that protects it from moisture or impact on the outside. With heavier motors in industrial applications, this casing is usually made from metal for added protection and durability. Inside the casing, the motor engages with a series of reduction gears when it is activated, and the torque from these turns the drive shaft that extends out of the gear motor unit. Typically, gear is also mounted on this exterior part of the drive shaft in order to exert force on whatever piece of equipment it is being used with. Another application of this can be found in a household or industrial garage door opener. A gear motor is installed inside the unit’s box, and this gear motor engages with a gear on a central drive shaft that turns a sprocket connected to the chain that pulls and lowers the garage door. Without a strong gear motor, it wouldn’t be possible for the door to be opened or closed at the push of a button.
Things to Consider When Purchasing Gear Motors
Gear motors that are purchased on their own for exterior installation usually have a mounting platform built on them so that they can be bolted directly to a surface. This secure setup ensures that all of the torque generated by the motor is used efficiently.
A gear motor manufacturer can consult with you about the best solution for the needs of your application. Having a motor that exerts enough power to accomplish your equipment process is critical if you want a reliable unit that doesn’t strain the motor.
