This motor, install a set of stator windings with the work of 90 degrees in the space of the ignition coil and ignition coil in series with a capacitor of the above, the ignition coil of the condenser can cause the current phase work before the actual settlement electrical approach angle 90 degrees, 90 degrees apart in space, the angle of the electrical windings of two phases is 90 degrees out of phase AC motor in the air box to produce a two-phase rotating magnetic field with magnetic motor capable of starting, increase the number to be transferred from a certain value. centrifugal switch turns off automatically start winding, the motor operates as a single.

Motor start capacitor AC induction motor is modified by a division phase capacitor in series with the ignition coil so you can start “pulse.” In the separation phase motor, capacitor start motor iduction also has a centrifugal switch that turns off the ignition coil and capacitor when the motor reaches about 75% of rated speed.
Since this motor is the capacitor in series with the starter circuit, it creates even more, starting usually 200% to 400% of rated torque. And the starting current, usually 450% to 575% of rated current is much smaller than the phase separation due to the larger wire in the circuit to start.

And a modified version of the starting capacitor is the start of the resistance. In this type of single phase induction motor, the starting capacitor is replaced by a resistor. The resistance of the starter motor is used in applications where the torque requirement is less than that predicted by the induction motor start capacitor. But beyond cost, this engine offers no advantage over the starting capacitor.

These induction motors are used in a wide range of broadband applications, as small companies, large fans and pumps as well as direct drive or many-oriented applications.
