Product Overview
Description
In the last several decades the single-phase AC motors have utilized mechanical centrifugal switches to switch from start windings to main windings which have problems like tolerance build-up, mechanical fatigue, vibration, electric spark, etc. Under normal environment motor failures often come from the degradation of the mechanical switches. Electronic Centrifugal Switch (EMS) is a reliable solid-state switch that would duplicate the functions of the conventional centrifugal switch with additional benefits of the electronic device. Speed voltage /current and phase are constantly monitored by the ECS, and the internal ASIC will control the switch On or Off. At the cut-Off point, the motor speed normally accelerates to 60~80% of the synchronous speed (see Figure 1 torque-speed curve). When the motor encounters overload conditions or the motor speed decreases to approximately 20~40% of the synchronous speed, ECS reconnects the start CAP.
