Patent attributes
Motor start circuit for an induction motor-with a main winding and an auxiliary winding having two end connections supplied with current via current supply connections, and with a start circuit device serving the purpose of stopping the current flow through the auxiliary winding after the start of the motor, and being connected via a conductor to a control device connected between the current supply connections, and with a preset timer device interacting with the start circuit device to stop the current flow through the auxiliary winding, as soon as a predetermined period after the start of the current flow has lapsed. With the purpose of optimizing the motor start circuit, a voltage presetting device, with which a predetermined voltage value can be set, the start circuit device being disconnected if this value is exceeded, and a period duration presetting device, are connected to or integrated in the control device.
