Before turning on an electric motor, it’s important to check for several additional factors in addition to the line voltage, such annoyance tripping, excessive nominal currents, and flickering or fading light, all of which are indicators of a bad power supply. CareLabs will send qualified personnel to your location to collect up-to-date and earlier motor installation data. Then calculations are performed to anticipate the future ramifications, and suggestions are made to lessen the impacts using the data gathered and manufacturer feedback.  

Both static and dynamic simulation techniques may be used to analyze motor starting procedures. We are especially interested in studies that mimic the conditions that occur when an electric motor starts, such as:  

  • Modeling the observed starting impedance of the electric motor results in the load flow solution.
  • The voltage drop technique is used for motor starting currents, whereas the short-circuit approach is used for pre-fault short circuit circumstances.
  • When a precise dynamic model of the electric motor circuit and load-torque characteristics is available, it may be possible to assess the effect using the dynamic model of the electric motor. traditional transient stability approach for motor starting.
  • Transient stability simulations may be used when complete dynamic model information for the electric motor is not available.

Argentina Needs to Analyze Motor Starts:

The size of electric motors and their use in modern industrial systems are both growing dramatically. The electric motor, locally linked loads, and electrically distant buses may all be disrupted by starting a large motor that is connected to a line. The terminal voltage should be at or greater than 80% of the rated voltage when starting an electric motor. Because the square of a motor’s terminal voltage is directly proportional to the torque, voltage difference affects the load torque of the motor. Machines that are already in motion may hit their breaking torque and slow down or halt if the voltage drop is considerable. Voltage dips affect a variety of things, including lighting loads, delicate control systems, and electrical equipment. High starting current also lowers terminal voltage, which raises the current consumed by all systems providing an ongoing load. Additionally, faulty undervoltage relays have been found.  

When Does a Motor Start Analysis Need to Be Carried Out?

  • Before or during the purchase of a large motor.
  • The supply transformer will trip if a generator is not available, and the motor rating is more than 30% of the base KVA rating.
  • If the generator is the only source of power for the system and the motor rating is more than 10% to 15% of the generator’s KVA rating, the generator has to be replaced.
  • If several motors start at once during an industrial process, a motor start study may be required.
  • Smaller power systems often have limited capacity, which makes it more challenging to start a motor with a big capacity due to voltage drop issues. The understanding of the output of small generator-containing systems is made easier by the examination of motor beginnings.

The Advantages of Motor Start Analysis:

Investigation of motor launch Utilizing a motor or starting technique with favorable speed-torque characteristics is beneficial. Any unexpected loads must be accelerated under supervision to prevent going above the equipment’s allowed torque limits. A motor start study may be used at any time to examine how the motor shaft is operating. As a result, it helps determine the allowable torque constraints for the machinery. The machine’s voltage and whether the electric motor can start and accelerate are determined by motor starting experiments. To further evaluate your electric motor, CareLabs provides motor start examinations by qualified experts. Furthermore, we provide motor start analysis services in all of Argentina‘s main cities, including Buenos Aires, Córdoba, Rosario, and Mendoza.
