PURPOSE: A motor auto change-over start controller is provided to operate safely and effectively the motors without a monitoring process by operating a device using two or three or more motors under an automatic operation mode. CONSTITUTION: A motor auto change-over start controller includes the first controller, the second controller, a common terminal, a start terminal, a standby signal input terminal, and a standby signal output terminal. The first and the second controllers include a power and operation circuit(10), a driving circuit(40), a signal processing circuit(60), and a controller(20), respectively. The power and operation circuit(10) selects one of a manual operation and an automatic operation. The driving circuit(40) is driven by an external switch(30) and an internal switch in order to control an operation of the first motor. The signal processing circuit(60) applies a standby signal to another controller when the driving circuit(40) is normally operated. The controller(20) applies a start signal to a standby motor and changes the present mode to the standby mode when the external switch(30) or the driving circuit(40) are in the abnormal states.
