Analysis of the Italian Motor Start
Care Labs offers Motor start research and analysis services to Italian enterprises. Our motor start analysis service seeks to identify unusual events when a large motor is started. Before starting an electric motor, there are more considerations than connecting it to the line voltage.
A power system is malfunctioning if nuisance tripping, high nominal currents, and flickering or fading lights occur. Care Labs will send trained staff to collect current and historical motor installation data. Then, using manufacturer data, calculations are conducted to estimate the future and build mitigation solutions.
Simulations both static and dynamic can be used to examine motor starting procedures. We focus mostly on dynamic motor beginning research that attempts to simulate motor starting circumstances such as:
- To achieve the load flow solution, the measured starting impedance of the electric motor is modelled.
- The short-circuit technique is used to compute the current under pre-fault short circuit conditions, whereas the voltage drop method is used to determine the initial current in a motor when it is turned on.
- When the electric motor circuit and load-torque characteristics are accurately modelled, the dynamic model of the electric motor may be used in a typical transient stability approach to assess the impact of motor starting.
- In the absence of a thorough dynamic model of the electric motor, transient stability simulations may be utilized.

Italy Needs to Do a Motor Start Analysis.
Motors are becoming more prevalent in contemporary industrial systems, and the size of electric motors is expanding exponentially. If you turn on a huge motor that is connected to the power line, it might cause severe problems for the electric motor, any neighboring loads, and even buses placed far from the motor’s position. A minimum of 80% of the rated voltage must be present at the motor terminal for an electric motor to start. Inasmuch as the square of a motor’s terminal voltage is directly proportional to its load torque, voltage difference has a direct effect on the load torque characteristic of the motor.
If the voltage loss is considerable, the load on the machines may exceed their “breakdown torque,” forcing them to decelerate or even stop. The voltage drop also affects other sorts of loads, such as electrical equipment, sensitive control devices, lighting loads, etc. In addition, high starting current affects terminal voltage, necessitating greater current for all systems that service a constant load. Low voltage relays have also been discovered to be broken.
When Is an Analysis of Motor Start Necessary?
- Prior to or during the acquisition of a huge motor.
- If there is no generator and the motor rating exceeds 30 percent of the supply transformer’s base KVA rating, a backup generator must be installed.
- If the generator is the only source of power for the system and the motor rating surpasses 10-15% of the generator’s KVA rating, the generator should be replaced.
- A motor start study may be necessary if many motors start simultaneously for an industrial operation.
- Since smaller power systems often have less power, voltage drop concerns are compounded when starting a motor with a high-power output. Examining how motors start might aid in comprehending the output of small systems with generators.
Analysis of the Pros and Cons of Motor Start
Determine how a motor begins. Choose a motor or starting technique with the best speed-torque characteristics for the task. To prevent exceeding the equipment’s torque constraints, certain loads must be accelerated in a controlled way. By performing a motor start test, you may at any time determine how the motor’s shaft performs. Consequently, it helps determine how much torque the equipment can tolerate. Motor starting research is needed to establish how starting affects the machine’s voltage and whether an electric motor can start and gain speed rapidly.
