Web2 dagen geleden · The breakdown torque point is much higher than the rated load torque point. For this reason, it takes quite an overload to stall the motor. The speed/torque curve shown in Figure 3-30 indicates the breakdown torque for a typical induction motor to be about 270% of the rated load torque. Operating a motor overloaded for an extended … WebThe Breakdown Slip of Induction Motor is the maximum slip developed in an induction motor. This slip is a measure of the short time overloading capability of the motor. The torque slip characteristic curve is divided roughly into three regions and is represented as s = R/X or Slip = Resistance/Reactance.
