Electric motors are an integral part of many modern industrial environments. They are equally notorious pieces of machinery that can be affected by a wide spectrum of issues. From overloading to bearing faults, there are lots of failure points to this critical component. Most of these issues can be identified and rectified proactively with the right set of tools and systems. That is where Technomax’s “Dynamic Electrical Motor Testing” service comes into play.
Dynamic Electrical Motor Testing services can be used to evaluate the health and performance of electric motors during dynamic conditions. According to the testing procedure, they are of two types viz. Dynamic Motor Analyzers and Static Motor Analyzers. Dynamic Analyzers test with the motor running, and the Static Analyzers test them without power supply. Both methods have their advantages and are effective in predictive analysis when used together. Dynamic Analyzers can collect data such as Voltage, Current, Load, Torque, Efficiency, etc., to provide a comprehensive status of the device being tested. Whereas Static Analyzer’s primary focus is on testing electrical factors by emulating worst-case scenarios.
Dynamic electrical motor testing is an effective way to systematically monitor and log test data over a period of time. With the continuous data, statistical analysis as well can be performed to identify failure points. Such a periodic inspection and analysis can significantly reduce machine downtimes. As professionals, we at Technomax understand how difficult the process of troubleshooting and analysis is when it comes to industrial electric motors. That’s why we recommend our Dynamic Electric Motor Analyzer service, which our professionals perform using cutting-edge machines like the Baker EXP4000. A high-quality, industry-approved tool that can provide you with concise analysis without any need for higher expertise. To start with, our engineers can clearly detect whether the root cause of a given motor issue is electrical or mechanical.
In this service, we derive data by measuring the voltages, currents, torque, etc., on a power-motor-load system. The route-based system can acquire data in several testing domains like Power Quality, Machine Performance, Current, Spectrum, etc., and store them for generating reports and trend analysis. Let's have a look at how and what kind of information can be inferred from these testing domains. Read more about Dynamic Electrical Motor Testing services.

Dynamic Electrical Motor Testing - Current
Voltage and Current imbalances are major areas of concern for power-motor-load systems, and these values should be checked periodically to identify issues beforehand. Using advanced equipment, Technomax experts can assess the current and identify current imbalances due to any prevailing issues. Loose connections, misconnections, iron saturation, etc., are some common problems that cause the motor to underperform which can be detected with the right equipment that can identify current imbalances.
The Technomax professional monitors Power, Voltage as well as Current levels/imbalances. Since there are several power quality issues that can affect the motor. Improper phase loads, improper filters, high resistance connections, etc., can cause thermal overloads or machine degradation over time and put unwanted stress on the motor. Power quality analysis helps in identifying these stress-inducing causes at the source.
Torque is dependent on load, mechanical conditions, etc., and is one of the main factors measured by the dynamic electrical motor analyzer. We use innovative torque analysis capabilities and take the assistance of the torque time and spectrum to diagnose mechanical issues. As the mechanical parts like bearings and shafts are more exposed to wear, and timely deduction of such issues saves a lot of time. Read more about Dynamic Electrical Motor Testing services.
Our engineers use the latest equipment like the EXP4000 to monitor a motor's health and productivity, as well as to determine the source of stress-inducing problems. To discover if there are any problems, the device examines effective service factors, load, operational conditions, and efficiency. Maintenance personnel frequently overlook operational equipment issues that might lead to motor failure, such as thermal overloads or machine degradation issues that impose an excessive amount of stress on a motor.
Under-performance of motors often goes unidentified as long as the machine satisfies the business needs. But the loss is on energy efficiency and deterioration of equipment. On the other hand, poorly performing motors are also inefficient to use of energy and a loss to the business as well. Technomax can help you identify such performance issues to decide whether fixing or replacement is required. Read more about Dynamic Electrical Motor Testing services.
Variable Frequency Drive Monitoring
VFD’s play a big role in industrial systems in controlling performance and increasing productivity. Energy savings, intelligent motor control, and reduction of peak-current draw are three great reasons to choose a VFD as the controller in every motor-driven system and they definitely pose a difficult challenge for maintenance professionals. But our engineers are capable of monitoring and troubleshooting VFDs and displaying a V/Hz relationship to time as well as speed and torque. This helps in identifying short-lived problems and exposes flaws in loop design between the VFD and load sensors.
Experts from Technomax can assist you in monitoring and displaying almost 6000 samples per second for all current, voltage, and torque values. This helps in accurate troubleshooting of motor issues on startup as well as other timing issues. It's also a great way to identify over-torquing, startup phase trips, etc.
Short-term or route-based monitoring will possibly miss machine system issues that occur rarely. Read more about Dynamic Electrical Motor Testing services. Using event triggers on up to 41 parameters, Technomax lets you constantly monitor machine systems for several days by gathering these events. It also provides the option to monitor voltage and current in DC motors.
Predictive Motor maintenance is the foolproof way to keep machinery in well-performing conditions. This is why Technomax's expert Dynamic Electrical Motor Analyzer Services is a valued addition in understanding existing issues as well as possible issues in a power-motor-load system. With our expertise in a wide range of supported testing domains, we ensure that our services cover the majority of the possible issues that could affect an electric motor.
