Low current electric motor starter
A low cost motor starter is shown having a PTC resistor 12 serially connected to a triac 14 and a bias resistor in turn adapted to be connected to the start winding of a single phase motor. A reed relay 16 having a sense coil 16a serially connected to the main winding in one preferred embodiment and...

| description | A low cost motor starter is shown having a PTC resistor 12 serially connected to a triac 14 and a bias resistor in turn adapted to be connected to the start winding of a single phase motor. A reed relay 16 having a sense coil 16a serially connected to the main winding in one preferred embodiment and in parallel with the main and start windings in a second preferred embodiment, is magnetically coupled to reed contacts16b, 16c. Reed contact 16b is connected to a location intermediate the PTC resistor 12 and the triac 14 while reed contact 16c is connected to the gate of the triac. A gate signal phase shifting network comprising capacitor C1-R2 is also connected to reed contact 16c and the gate. |
