Factors to Consider When Buying an Electric Motor


With the wide range of inventions and discoveries in the field of Physics, electric motors came into existence. Electric motors are capable of converting electrical energy into mechanical energy when connected to a source of electricity. They provide power through their constant motion that can run various devices, which is why they have been extensively used in industrial areas as well as in the home appliances.

If we talk about homes, they are used in various appliances, tools, instruments and help gadgets and devices like automatic doors, ceiling fans, gas pumps, etc. to run. If we consider their usage in industrial sector, electric motors have made their way into all sorts of heavy as well as light machines used in the manufacturing and production units.

Why Choose Electric Motors?

Electric motors are more reliable as compared to conventional motor engines that are designed with 200 parts, whereas an electric motor has 20 moving parts which make it more compatible for use. With the usage of electric motors, the wear and tear and risks associated with damages have reduced to a fair amount.

The good news is, manufacturers, can now modify electric motors to meet the requirements, for instance, the addition of cables to the electric motor can prevent breakage of the terminal by mistake when struggling to attach cables. Besides, brackets or mounting plates, lead screws, gears and pulleys can also be added in the customization list of electric motors.

For a particular application, you must consider factors like voltage, torque, power and speed to ensure whether the electric motor serves your purpose. Let us look at some of the factors-

1) Voltage- Do you need a wall outlet, or are you up for running your motor on batteries? Using an electric motor for industrial purpose requires a voltage of 230+ volts, considering the wall outlet and the voltage standard is about 115 volts.

2) Frequency- The range for frequency must lie between 50Hz to 60Hz for your electric motor to operate.

3) Speed- The electric motors are available at a set speed or a speed range where you can change the required speed for your operation. If you are looking for a motor where you can add both exact as well as adjustable speed, you need to add a control to the motor.

4) Torque- Depending upon the work you require motor for, here are some questions to consider before you choose one-

  • How much starting torque do you need?
  • Is gravity need to be considered?
  • Do you want the varying torque during the motor’s speed of operation?

5) Power- The motor you are using must be able to provide the power required for the process and simultaneously should draw or consume a moderate amount of electricity to do the work. Besides, you must know whether you are using running power or maximum power.

6)Enclosure Rating & Environment- Exposure to certain environmental factors can damage the electric motor. For instance, dust can jam the engines and water can cause short circuits. Motors can come with all sorts of protection.
