Intermittent movement type strong magnetic motor
An intermittent movement type strong magnetic motor having a control device (PLC) for first controlling an arresting device to lock an electromagnetic coil, then controlling a power supply device to start power supply. After a given length of time of power supply when the current rises to the highest point or rises to a level as required, the arresting device releases the electromagnetic coil quickly to allow the electromagnetic coil to move and operate immediately. The intermittent movement type strong magnetic motor maximally avoids restriction of counter-electromotive force and makes full use of the great action force created between magnetic fields and the electromagnetic coil, thereby ideally converting magnetic forces to mechanical energy and increasing energy efficient ratio of the motor.
