There are numerous types of motors out there in the world nowadays, and each is used for specific reasons. Here we will be talking about gear motors and why you need to be using one.
What Are They?
Gear motors are a combination of an electric motor and a reduction gear train. Its goal is to work on low horsepower while providing a high torque. Like most others, gear motors can run as either an AC or DC motor, alternating or direct current; the difference between the two being the power behind the torque.
Gear motors can be seen in the industrial workforce in things like:
- Low-speed lifts
They are also used in a household’s daily life:
- Washing machine handles
- Electric can openers
- Garage door openers
- Electric alarm clocks
How Do They Work
For the most part, these types of motors are used for strong jobs that must be done at a slow speed. They slow the gears used throughout the motor, creating higher torque. This allows smaller motors to move large objects. This is done by attaching a gearbox to the motor in question and lowering the speed output. The example usually given is that of an electric clock. The motor used to power the clock will have between 1200 – 1500 revolutions per minute. When you add in the separate gearbox, the gears slow the revolutions to about 1 per minute, which is what we see when watching a minute hand tick by. The same goes for the hour hand; it is set differently depending on the speed of the motor used.
In the professional world, you will see these, as stated above, in slow moving lifts or cranes. The same principal applies but in a different way. The amount of gears needed is more substantial since the motors used in these objects tend to be stronger. When the gears are applied, they slow down the movement significantly. When this happens, the power the motor is producing builds up; this is known as torque. The amount of torque building up is determined by the strength and output of the motor. When the gears finally allow the object to move, the torque that has been sitting can do its job and lift whatever needs lifting. Had the motor been allowed to lift the object on its own, there would not have been enough torque to do so.
Why Should You Use It?
Due to the ability to create extra torque where there was none, almost any motor can be used for most heavy lift jobs. This is great because it’s economical; almost any motor, at any price, can be used for your projects. Motors can be purchased with gearboxes already attached in a ready to go package. This is an easier alternative to building one yourself, especially if you are in a time crunch.
How Do You Know What Kind To Use?
Choosing a gear motor is no different than picking out a normal motor, you must look at the specs first. You can check this website and determine what you need to get the job done.
- How much torque is required to get the job done?
- Is this being used indoors or outdoors?
- How much power (voltage, amps, etc.) will be put into the motor?
Once you have answered all of the general questions, finding the right gear motor for you will be no problem at all.
