Capacitors wired in series with the starting winding provide:

Capacitors in series with the starting winding create a phase shift between the currents in the start and main windings, producing a more effective rotating magnetic field. That stronger rotating field generates much higher starting torque, helping the motor begin to run from standstill. After it starts, the starting winding (and capacitor) is typically removed so running torque relies mainly on the main winding. Without the capacitor, the phase difference is too small, giving much lower starting torque; with no torque or the same torque as the run winding, the motor wouldn’t start reliably.
