amortisseur winding
（ plural ）
Quizzes for review
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.
amortisseur winding
In a synchronous motor, the amortisseur winding — a squirrel-cage winding placed near the surface of the pole faces whose end turns are shorted at each pole — both damps speed fluctuations caused by sudden load changes and, by the currents induced as the rotating field passes, produces torque during starting to accelerate the motor and overcome its speed lag.
