Abstract

Automatic and rapid machine for the punching of slots in the rotor and stator sheets of dynamous and electric motors. The table carrying the circular sheet to be punched is driven by a stepwise motor which is controlled electronically. It is connected directly to the table or a reducer is interposed. The eccentric drive shaft of the tool ram is associated with an impulse emitter which sends an impulse to an electronic counter between set points on the table corresponding to the start and end of advance. The counter is set according to the number of punchings to be carried out and transmits to the motor each time the number of impulses necessary for one punching step.
