Guide in Choosing the RIGHT Motor
AC * Speed Control * Stepping * Servo MOTORS
Found a useful guide on how to determine the correct motor for your application. Let me share the important points to make the choosing part easier for you. With so many variables to consider, it is no wonder many designers find it difficult to choose the right motor for their application and often overlook critical parameters along the way. These pointers will definitely help you make the right choice.
How fast does the motor need to run? Check the rated or constant speed and maximum or peak speed of the motor you are considering. Can the motor, coupled with a ball screw or gearbox, provide the speed required for your job?
Torque and Inertia
Torque, the amount of radial force on the motor shaft, is another primary consideration. Can the selected motor provide enough torque to move your load? Keep in mind that coupling the motor with a gearbox will help to achieve torque but you must ensure you have enough speed to make them effective.
Is there a size restriction in your application? If you are building a small part, or something where mass is concerned, a large 5 lbs. motor may not be ideal for you.
How do you plan on sending commands to your motor? Will you need to communicate with multiple motors or be covering large distances between motor and control box? Different motors offer different communication options and add-ons.
Accuracy and Resolution
How accurate do the motors have to be? Are you measuring minute dimensions with a sensor that requires large amounts of precision? Are you simply moving a large plastic piece from one conveyor to another?
Some motors, usually basic steppers, offer a lower resolution, meaning less steps, pulses or small movements per one revolution of the motor shaft. Servos usually offer a high resolution, offering up to 50,000 pulses per revolution. The finer your move needs to be, the higher the resolution of your motor should be.
In what environment will your motor be running? Will there be a large amount of dust, particulate or water coming into contact with the motor. Some motors are water resistant; others offer shaft seals which help prevent particulates from getting into the inner workings of the motor through the shaft.
What is the temperature and airflow like in the area the motor is to be placed? Heat is a concern when it comes to operating motors. They often have a specific temperature range at which they should be run. Motors produce heat when running, therefore fully enclosed areas with no air circulation may cause motors to overheat.
How much are you looking to spend on your motor? Often times, this is the deciding factor. You should have an idea of how much you are willing to spend and look for a motor accordingly.
Sure this guide from Design Engineering can be a BIG Help. Don't forget considering Oriental Motor as your brand when it comes to ac motors, stepping motors, speed control motors, servo motors and controllers. They have wide arrange of different motor types which might be the one you need. LSG Industrial Supplies in Clark, Angeles City is the oriental motor distributor in philippines. So what are you waiting for? Buy the motor that match your application now!
