The maximum value of torque that a synchronous motor, can develop without losing its synchronism, is known as
Pull out Torque
Breaking Torque
Pull-in Torque
Slip Torque
Pull out Torque
The correct answer is A) Pull out Torque ┬╖ This is the maximum torque that a synchronous motor can develop while remaining in synchronism with the supply frequency.
The correct answer is A) Pull out Torque ┬╖ This is the maximum torque that a synchronous motor can develop while remaining in synchronism with the supply frequency.
The pull out torque occurs when the synchronous motor experiences maximum load before it begins to lose synchronism ┬╖ It is determined by the machine's design, the rotor's speed, and the magnetic field produced by the stator windings.
The pull out torque is crucial for ensuring that the motor operates effectively under varying load conditions.
Exceeding the pull out torque can lead to a loss of synchronism, causing the motor to stall.
High efficiency under load conditions.
Maintains constant speed across a wide range of loads.
Sensitive to overload conditions.
Requires precise control of operating parameters.
Used in applications requiring constant speed, such as in electric trains.
Ideal for large industrial loads where the torque requirements are stable.
The pull out torque is typically higher than the rated torque of synchronous motors.
Option B (Breaking Torque) refers to the torque at which the motor stops rotating and does not maintain synchronism.
A is correct тАФ The pull out torque is the maximum torque a synchronous motor can develop without losing synchronism.
Understand the importance of torque in motor performance and how it affects efficiency and operational stability.
