Abstract

A switch assembly including a switch (e.g., an electronic switch) and a controller connected to the switch to control the switch. The switch assembly can also include a power supply connectable to a power source and connected to the controller. The power supply is configured to receive power from the power source and controllably power the controller. The switch assembly can also include a generator and decision logic. The switch assembly can be used in an electric machine (e.g., a motor).

Description

technical field [0001] The present invention relates to an electronic switching assembly and, more particularly, to an electronic switching assembly for controlling current flow through a circuit, such as a motor auxiliary circuit (eg, an auxiliary starting circuit). Background technique [0002] Single phase induction motors of the split phase and capacitor start types typically have a start winding that is connected to the power supply when the motor is started. However, once started, the start winding is usually removed, causing the motor to become more efficient. One reason for removing the start winding and start capacitor (if present) is that the start winding and start capacitor are not typically designed for continuous duty. That is, these components will fail if left unchanged in the circuit. A common solution to this problem is to connect an electronic switching circuit in series with the start winding (and start capacitor) to control the current through the star...
