Motor Testing Services — Speed Factors
Motor Diagnostic Systems • Oct 13, 2020

Do you have a short-term need for motor testing and performance data? Is one or more of your motors functioning suboptimally? If so, we urge you to get in touch with a member of our team, here at Motor Diagnostics Systems. 

Our quick-turnaround motor performance testing can be performed in our lab or on your site — allowing you to get the performance data that you need quickly and efficiently. At Motor Diagnostics systems, we offer the following motor testing services:

  • Torque vs speed
  • Power output vs speed
  • Efficiency and power factor vs speed
  • Voltage & current vs speed
  • Friction vs speed
  • Measured rotor inertia
  • Startup & coastdown speed profiles
  • Vibration
  • Temperature and thermal time constant

While we offer a number of motor tests that can diagnose motor issues and inefficiencies, in today’s blog we will be speaking about the motor tests that we conduct that relate to motor speed. Continue reading to learn more about our motor testing services.

Motor Testing — Speed Factors

When it comes to testing the efficiency of a motor, there are a number of speed-related factors that we take into account. How much torque is being produced compared to the relative speed? How much is friction influencing the speed of the motor? How does the efficiency and power factor fluctuate as speed is increased or decreased? All of these questions and more can be answered with the use of our motor testing services and diagnostic tools. 

Torque vs Speed

Torque and speed are key variables in determining the power required for a motor to operate efficiently. Torque is the amount of rotating force that the motor develops and is measured in pounds per force inch or lb-in. Speed, however, is the rate in which a motor spins — or the rotations per minute (RPM). If a motor provides maximum speed while only meeting minimal torque, a motor might experience operational issues. If a motor meets the needed torque rating but fails to meet the proper speed, the motor will be out of balance and will need some tweaking in order to make it more efficient. At Motor Diagnostics Systems, we have the tools and experience to measure the torque and speed of your motor in order to deem it operational or in need of a service.

Power Output vs Speed

The relationship between power output and speed is rather simple. The more power that you apply to a motor, the greater the speed the motor can reach. That said, there is a balance that should be reached rather than simply adding more and more power output to a motor. Because the power output of a motor determines the torque of the mortar and the speed of the motor, it is important to identify a voltage that achieves the desired motor speed without providing the motor with more power than it might need — meaning that power output can be adjusted and tweaked to meet the needed speed requirements. Using a number of motor diagnostics systems and testing tools, our team can help to determine the efficiency of how your motor is operating in relation to the amount of power that you are supplying to the motor. 

Efficiency In Power Factor vs Speed

One of the best ways to increase the efficiency of your motor and create some serious energy cost savings is to develop a greater understanding regarding your motor’s efficiency and operating characteristics. The efficiency of your motor is measured by the ratio between the amount of work that the motor can perform in relation to the electrical power that it consumes while performing said work. The power factor is an energy cost-reduction measure but is not a true measurement or energy savings. This means that improving the power factor can reduce energy costs, but it is usually influenced most by the electric utility rates that the motor is operating on. In order to ensure that your motors are operating as efficiently as possible, consider having them tested by our team. 

Voltage & Current vs Speed

There are many different relationships within a motor’s system that might dictate whether or not it’s working efficiently — and as you can likely tell, many of them are incredibly similar. All of the factors that we have discussed so far on today’s blog have an impact on speed. That said, voltage, and the current that it travels along can also affect speed. If a current is running inefficiently or if voltage levels are not correctly calculated, a motor might have to “work” too hard to achieve desired speeds. A simple voltage and current test on your motor can indicate whether or not the current and voltage is properly adjusted for any individual motor. At Motor Diagnostic Services, we have the tools and experience to help you diagnose motor inefficiencies and correct them accordingly. 

Friction vs Speed

Last, but certainly not least, friction is an important factor in determining whether or not a motor can reach desirable speeds efficiently. If there is too little friction, a motor can speed up and become too difficult to regulate speed. Additionally, if there is too much friction within an operating motor, it can require you to provide the motor with more power — decreasing the efficiency of the motor and increasing unnecessary ware. By testing your motor for friction and speed, we can determine whether or not your motor is functioning optimally, or if it needs to be adjusted to function properly. 

For Motor Testing, Think Motor Diagnostic Systems

The best way to determine whether or not your motors are functioning properly is to have them tested by a member of our team. Combining our industry experience and innovative motor testing tools, we can determine whether or not your motor is functioning as optimally as it should. Whether you want to have your motor tested in your facility or ours, Motor Diagnostic Systems is here to ensure that your motors are operating efficiently while your operating costs are decreased.
