Factors to Consider When Buying an Electric Motor

Factors to Consider When Buying an Electric Motor


With the wide range of inventions and discoveries in 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 and in-home appliances.

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

Electric Motor

Why Choose Electric Motors?

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

The good news is that 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 to electric motors’ customization list.

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

1) Voltage- Do you need a wall outlet, or are you up for running your motor on batteries? Using an electric motor for industrial purposes 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 an engine that can add both exact and adjustable rates, 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 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.
