Taking into account the construction factor, the permanent condenser electric motor has a smaller size and is generally free of the need for periodic maintenance, since they do not use contacts and moving parts, as in other types of engines found. However, the starting torque is significantly lower than that of the split-phase motor, which changes in average 50% and 100% of the nominal torque, a factor that can be definitive in case it is necessary to limit its application to equipment that generally does not need high starting torque.

In this type of permanent condenser motor the auxiliary winding as well as the condenser are permanently active, the condenser being electrostatic. The effect of this capacitor is to operate in the creation of flow conditions considered very similar to those found in multiphase motors, increasing in this way the maximum torque, its efficiency and the power factor, thus having the ability to significantly reduce noise. Centrifugal pumps, grinders, drills, blowers, various office machines, fans, exhaust fans, small saws, air conditioners and sprayers, among other equipment, can be mentioned.
