For most mechanical and electric design engineers, deciding on the right gearmotor can be a challenging task. This is mainly because of the various factors that must be considered when choosing among different gearmotors. So, whether you are planning to purchase a made gearmotor or a gearbox and a motor separately, it’s crucial that you understand the different application requirements to find a perfect option. Here are the three tips to keep in mind when specifying gearmotors for your particular application.
#1. Determine your application requirements
The very first step to finding the most suitable gearmotor you need is to review all your application requirements. These include knowing the general requirements first such as mounting type, size, and orientation, envelope size, overhung and side loads. Next is to decide on the input power source you need such as frequency, voltage, and maximum current.
You can then proceed on knowing the specifics of gearmotors, including weight, size, lifespan, maintenance, and noise level. In terms of performance, consider torque, speed, horsepower, duty cycle, and load. Finally, don’t forget about the environmental factors like temperature and ingress protection rating, if applicable.
#2. Choose the correct motor
Since every application is unique and requires a different set of parameters, it’s vital that you select the right motor. This means noting which particular factors are critical for your application. Then use it to compare to the motor specifications of various types of gearmotors you prefer to use. It is during this stage that you can think whether you’d better off purchasing a gearbox and motor in separate terms.
#3. Determine the torque and speed requirements of the machine’s load
One sure way to make sure that you have chosen the right gearmotor is to specifically identify the output speed, and starting and running torque it has to see. It is a matter of matching the needs of your application to the torque and the requirements of your machine. Just remember that when you prefer a pre-engineered gearmotor, the manufacturer has done most of the work in making sure that the motor and gearbox match seamlessly.
