Motor Start Analysis

Indian businesses may take use of CareLabsspecialized Motor start study and analysis service. Assessing the unusual consequences of starting a large motor is the main goal of our motor start analysis service. Before turning on an electric motor, it’s important to check for a number of 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 recent and previous motor installation data. Then, using the information gathered and the manufacturer’s input, calculations are performed to determine the future consequences, and suggestions are offered to lessen their impact. Both static and dynamic simulation techniques may be used to analyze motor starting procedures. Research that mimics the conditions that occur when a motor starts concerns us greatly. 

  • The load flow solution is produced by modelling the electric motor’s observed starting impedance.
  • The voltage drop method is used for motor starting currents, whereas the short-circuit approach is used for pre-fault short circuit circumstances.
  • The dynamic model of the electric motor may be used to determine the impact of motor starting in a traditional transient stability technique if a detailed dynamic model of the electric motor circuit and load-torque characteristics is provided.
  • Transient stability simulations can be used when complete dynamic model information for the electric motor is not available.

India Requires a Motor Start Analysis:

Electric motor sizes and their use in modern industrial systems are both increasing dramatically. The electric motor, locally linked loads, and electrically distant buses can 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 drops affect, among other things, lighting loads, delicate control systems, and electrical equipment. High starting current also lowers terminal voltage, which raises the current consumed by all systems supplying an ongoing load. Relays with defects from under voltage are also found.

When Is It Appropriate to Do a Motor Start Analysis?
  • Before or during the purchase of a large motor.
  • The supply transformer will trip if there is no generator available and the motor rating exceeds 30% of the base KVA rating.
  • If the generator is the only source of power for the system and the motor rating is greater than 10% to 15% of the generator’s KVA rating, the generator has to be replaced.
  • If many motors start at once during an industrial process, a motor start study may be required.
  • Smaller power systems frequently 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.

Benefits 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 close monitoring to prevent going beyond the equipment’s permitted torque limits. A motor start study can be used at any time to analyze how the motor’s shaft is operating. As a result, it helps determine the allowable torque constraints for the machinery. 

The machine’s voltage and the ability of the electric motor to start and accelerate are determined by motor starting experiments. To further evaluate your electric motor, Care Labs provides motor start investigations by qualified experts. All major Indian cities, including Delhi, Mumbai, Chennai, Bangalore, and Hyderabad, may take use of our motor start analysis services.
