I. Hierarchical Position in Motor Categories
1. Fundamental Classification Framework
Motors are broadly categorized by power supply type:
plaintext
Motor Classification
├─ DC Motors
│ ├─ Permanent Magnet DC, Brushed DC, Brushless DC (BLDC), etc.
└─ AC Motors
├─ Synchronous Motors
│ ├─ Permanent Magnet Synchronous (PMSM), Wound-Field Synchronous, etc.
└─ Asynchronous Motors (Induction Motors)
├─ Single-Phase Induction, Three-Phase Induction
2. Core Attributes of Three-Phase Asynchronous Motors
- Power Source: Operates on three-phase AC power (50Hz/60Hz standard frequencies).
- Working Principle: Relies on "slip" between rotor speed and rotating magnetic field (asynchronous operation). Torque is induced via electromagnetic induction, eliminating the need for external DC excitation.
II. Technical Features & Application Scenarios
1. Structure & Operation
- Stator: Three-phase windings spaced 120° electrically, generating a rotating magnetic field when energized.
- Rotor Types:
- Squirrel Cage: Conductive bars (aluminum or copper) cast into rotor laminations. Simple, robust, and cost-effective (90% of industrial applications, e.g., fans, pumps).
- Wound Rotor: Features slip rings for external resistance connection, enabling speed control. Used in high-torque startups (e.g., cranes, rolling mills).
2. Comparison with Other AC Motors

Capacitor/resistor start |
| Efficiency |
80%-95% (Medium) |
90%-98% (Higher) |
50%-75% (Lower) |
| Typical Uses |
Industrial drives (pumps, compressors) |
Generators, precision drives (elevators) |
Household appliances (fans, washing machines) |
III. Market & Technological Significance
- Market Share: Dominates industrial motor applications (>70%), especially for constant-speed, high-torque loads (e.g., mining equipment, machine tools).
- Advantages:
- Simple construction, low maintenance (no brushes or complex excitation systems);
- Grid compatibility, direct connection to three-phase power, ideal for large-scale industrial use.
- Trends: Variable frequency drives (VFDs) enhance speed control, expanding applications, though asynchronous motors remain irreplaceable in mid/low-end heavy-duty scenarios.
