Why is there a delay required after a motor starts before it can be started again?
Personal opinion: The inrush current and load are high during startup; this is mainly to protect the motor
The issue of intermittent starting of motors is mainly considered in relation to motors with relatively large capacities. This is because large-capacity motors have large rotors and high moments of inertia; they require a long time to start, generate high inrush currents during startup, and are prone to overheating. Frequent starting can thus lead to motor overheating. To prevent motors from overheating, there are certain requirements regarding the interval between shutting down and restarting larger motors.
