GENERAL INFORMATION – The capacitors generally defined as motor capacitors are used for the start up and running of single-phase induction 2 and 3 windings motors. The capacitance of these capacitors (permanent connection) must be carefully established to avoid possible overheating of the auxiliary winding.
CONSTRUCTION PECULIARITIES – For the construction of these capacitors a polypropylene film dielectric is used, metallised in high vacuum, self-healing that allows the obtaining of capacitive units with very low losses and reduced overall dimensions. These elements are subsequently encapsulated in plastic case and then incorporated in resin.
