What Are The Factors To Consider Before Buying An Electric Motor

You can find the electric motors in everything from electric trains to remote-controlled cars these days, and you might be surprised how common they are. In fact, there are electric motors right now in the room where you are sitting. For instance, there is an electric motor in the hard drive of your computer and another in the cooling fan. When looking to buy a gear motor or electric motor for your application, it is significant to consider requirements like speed, power, torque,duty cycle, life cycle,and voltage.



Voltage: You will have to consider whether or not you will have access to a wall outlet or if you need the product to run on batteries. In case a wall outlet is available, it comes down to whether the voltage is standard, as in 115 volts or industrial, as in over 230 volts.


Frequency: Motors usually run at sixty hertz for the products that operate within the United States of America, but if the product is expected to be used outside the USA, you might have to consider something around fifty hertz or more than that.

Speed And Torque: Motors can come with a speed range or a set speed. You will have to choose if you want adjustable or exact speeds, and accordingly, you can add controls to the motor. You will also need a certain level of starting torque for the application. You must consider whether you want the torque requirement of the motor to change according to the period of operation of the motor. Start by thinking of the worst-case scenario for the amount of torque you would need and go from there.


Duty Cycle: Some of the applications run continuously, which means long enough for the motor to reach its full operating temperature. Others are run in a short burst to let the motor cool down between cycles. Motors that run alternatively can usually use a smaller motor than the applications with the same speed and torque but run nonstop.


Power: The power you think the application needs might not be equal to the power that it actually ends up using. So, at the time of looking at the specifications, make sure to know if you are using maximum power or running power.


Life Cycle: According to manufacturers like Rozum, applications that run very occasionally can often get by with the shorter life cycle and higher maintenance needs of DC and Universal motors.


Depending on your application or specific needs, there might be additional factors to look at. If you are not sure which of these specifications is vital to your application, talk through the list with the manufacturer to make sure you get fitted with the proper motor.
