Question regarding 3-phase induction motor
Understand the Problem
The question relates to 3-phase induction motors, which are commonly used in industrial applications. It likely seeks information about their operation, characteristics, or applications, necessitating knowledge in electrical engineering.
Answer
Key points: stator and rotor separated by air gap; slip ring motors use resistors to increase torque; self-starting; rotor frequency depends on slip.
It appears you are looking for important details and typical questions concerning three-phase induction motors. Some key points to note:
- Main Parts: It consists of a stator and a rotor, separated by a small air gap.
- Slip Ring Motors: External resistors can be connected to increase starting torque and decrease starting current.
- Self-Starting: Three-phase induction motors are generally self-starting with varying torque levels.
- Frequency of Rotor Current: Determined by the slip of the motor.
