An induction motor's rotor can be either wound type or ????????-???? type.

- In programming languages, an abstract type is a type in a nominative type system that can be instantiated directly; a type that is not abstract – which can be instantiated – is called a concrete type.
- In programming languages, an abstract type is a type in a nominative type system that can be instantiated directly; a type that is not abstract – which can be instantiated – is called a concrete type. A: 正确 B: 错误
- In typical induction motors, the stator winding is connected to the source and the rotor winding is short-circuited for many applications, or may be closed through external resistances. Herein, we can also call “stator winding” and “rotor winding” the ( ) respectively. A: armature winding and field winding B: field winding and armature winding C: motor D: stationary
- The key in the dictionary can't be a dictionary type, but value can be a dictionary type. A: 正确 B: 错误
- Does induction motor require a permanent magnet?
