Which of the following statements is/are accurate regarding working principle of a reluctance start motor?

1. In reluctance, motor reluctance torque can occur once a ferromagnetic object is located within an exterior magnetic field, then the object can be line up through the external magnetic field.

2. The torque can be generated among the two fields which twirling the object in the region of the line through the magnetic field so the torque is used on the object to provide less reluctance for the magnetic flux.

Working Principle of a Reluctance Start Motor:

Reluctance start motors operate based on the principle of reluctance torque. Here is an analysis of the given statements:

Statement 1:

• In a reluctance motor, reluctance torque can occur once a ferromagnetic object is located within an external magnetic field. Then the object can align with the external magnetic field.
• This statement is accurate. Reluctance torque occurs when a ferromagnetic object (such as the rotor of the motor) is subjected to an external magnetic field. The object tends to align itself with the magnetic field to minimize the reluctance, or opposition, to the magnetic flux.

Statement 2:

• The torque can be generated among the two fields which twirl the object around the line through the magnetic field, so the torque is used on the object to provide less reluctance for the magnetic flux.
• This statement is also accurate. The interaction between the magnetic field produced by the stator and the rotor's magnetic field generates torque. This torque acts on the rotor, causing it to align in a position where the reluctance is minimized, thereby producing rotational motion.
   

Conclusion:

Both statements 1 and 2 accurately describe the working principle of a reluctance start motor.

Therefore, the correct option is:

2) Both 1 and 2 are true
