A squirrel cage winding placed near the surface of the pole faces of a synchronous motor. Its main purpose is to dampen any speed fluctuations or oscillations that may occur as a result of sudden load changes. It is also used to accelerate the motor during starting. All the windings are shorted at the two ends of each pole of the motor. As the rotating field moves past the winding it induces currents in the winding which produce torque and accelerate the motor so as to overcome the lag in its speed.

Japanese Meaning
同期電動機の極面近くに配置されたスクイレルケージ巻線で、急激な負荷変動による速度の揺らぎや振動を抑制する（ダンピング）役割を持ち、始動時にはモーターの加速にも寄与する。各極の両端で巻線が短絡され、回転磁界が巻線を通過する際に電流を誘導し、その結果発生するトルクで速度の遅れを補う。
