📣❔ What happens when fan rotation is blocked? When a unit's rotor is unable to rotate, it enters a locked rotor condition, causing the current draw to increase. The unit’s response varies based on its design. Current will continue to rise until motor failure occurs or the unit's locked rotor protection kicks in, limiting current until the unit is powered down. Without intervention, damage to the motor or electronics is inevitable. Fans equipped with locked rotor protection can prevent catastrophic motor failure during a locked rotor condition. This protection ensures that, even after a locked rotor event, the fan will likely not suffer significant damage. If repair is needed, the motor generally remains intact, avoiding the need for full replacement. Have more questions for our engineering team?

In windings, negative temperature coefficient (NTC) thermistors are commonly used. NTC thermistors are employed to monitor the temperature of motor windings or transformers. They help protect the equipment from overheating by reducing the current or triggering an alarm when the temperature exceeds a critical threshold.
