are in proper relationship. These relays will open if the motor falls out of step because of a momentary overload or voltage dip. Synchronous operation is automatically restored when voltage returns to normal or the overload is removed. In some cases, resynchronization may not be desirable from a safety standpoint. In such cases, the controller can be designed to disconnect power from the stator. Out-of-step protection is provided by a conventional thermal-overload device (OSP). This device is energized...

ventilation. On the other hand, temperature-responsive devices protect against running overloads that produce a gradual increase in winding temperature. Line-break thermal protectors are prevalent in smaller motors, while control-circuit systems are common on larger motors. Thermistor systems provide complete protection with small sensors in the motor. In many high-slip induction motors, the critical temperature occurs in the rotor. Temperature measurement requires slip rings and brushes... (read more)Browse Motor Controllers Datasheets for Sinotech Motors -
