Motor Starting Analysis

  1. Static motor starting
  2. Dynamic motor starting
Editing motors information.
Edit study case option

Static Motor Starting

Notice the changing in current reach to the steady-state after 1 second.
Bus-bar voltage curve (% of the system voltage in my case is 400 V)

Dynamic Motor Starting

  1. Motor model or it equivalent circuit
  2. Motor inertia
  3. load model
Motor model data
In load model page you may chose fan, pump, etc.
In case you do not know Motor inertia you may use the typical values
Run dynamic study option and drag the time-slider to the right
Voltage across Bus-Bar 2
Current draws by the Motor
Gradually increasing the speed of the motor
