TREATMENT UNIT COMPRISING MEANS FOR CONTROLLING AN ELECTROMAGNETIC ACTUATOR AND ELECTROMAGNETIC ACTUATOR COMPRISING SUCH A PROCESSING UNIT

摘要

Processing unit (2) comprising control means (21) for acting on at least one excitation coil (3) for moving a movable armature (12) of an electromagnetic actuator (100), said control means (21) generating a periodic voltage wave frame comprising at least n rectified alternations. At least one alternation comprises at least one first and at least one second excitation pulse sequence, the first excitation pulse order beginning substantially at a zero voltage of one half cycle, and the second pulse control pulse ending substantially at a zero voltage of said alternation. The electrical energy generated by the pulse orders of excitation of a first halfwave is less than or equal to the electrical energy generated by the pulse orders of excitation of a second alternation posterior to said first halfwave.
