Blockage detection for single-phase synchronous motors
With capacitor motors it is usually possible to detect a blockage by a clear increase in engine current.
With single-phase synchronous motors a blockage can only be detected, due to the construction, by increasing the auxiliary phase voltage.
In general, blockages of motors and gears should be avoided, as they could shorten life-span or lead to damage.
However, in some applications this is not always possible. As a result, ROTEK has developed a simple circuit which recognises blockages on single-phase synchronous motors.
