转子/电枢

Rotor/Armature is the rotating component in electric motors and solenoids that converts electrical energy into mechanical motion through electromagnetic induction.

技术定义与适配语境
典型 转子/电枢 会按材料、尺寸公差、适配关系和失效风险在 电气设备制造 中评估。

The rotor (in AC motors) or armature (in DC motors) is the central rotating part of an electric motor or solenoid, consisting of a laminated iron core with conductive windings or bars. When energized, it interacts with the stator's magnetic field to produce torque, enabling rotational motion. In solenoids, it functions as the movable plunger that creates linear motion when magnetically actuated.

定义
The rotor (in AC motors) or armature (in DC motors) is the central rotating part of an electric motor or solenoid, consisting of a laminated iron core with conductive windings or bars. When energized, it interacts with the stator's magnetic field to produce torque, enabling rotational motion. In solenoids, it functions as the movable plunger that creates linear motion when magnetically actuated.
工作原理
Operates on electromagnetic induction: when current flows through windings, it creates a magnetic field that interacts with the stator's field, generating Lorentz force and producing rotational torque (in motors) or linear force (in solenoids).

常见问题

What is the difference between rotor and armature?

Rotor refers to the rotating part in AC motors, while armature specifically denotes the rotating winding assembly in DC motors that carries alternating current. Both serve similar functions but differ in construction and current type.

How do you maintain rotor/armature components?

Regular inspection for insulation damage, bearing wear, and balance issues; cleaning to prevent contamination; and testing winding resistance and insulation resistance periodically.
