A small and specialized electrical machine, commonly referred to as a micro motor, is designed with a compact size and limited power output, typically below several hundred watts. These motors are specifically engineered to meet the unique demands of various applications, including control systems, where they play a crucial role in detecting, processing, amplifying, executing, or converting electromechanical signals or energy. They are also widely used for transmitting mechanical loads and providing AC or DC power to different equipment. Micro motors find extensive use in disk drives, copiers, CNC machines, and robotic systems.
**Types and Models of Micro Motors – Common Types**
Micro motors come in a wide variety of types and can be broadly categorized into 13 main groups: DC motors, AC motors, servo motors, stepping motors, rotary transformers, shaft encoders, AC/DC motors, tachogenerators, inductive synchronizers, linear motors, and other special-purpose motors. Each type is designed for specific functions and environments, making them essential components in precision-driven systems.
**Micro Motor Type and Model – Understanding the Naming Convention**
The naming convention for micro motors usually follows a structured format that helps identify key characteristics:
- The **first letter** represents the shape: 'R' for round, 'F' for flat, and 'S' for square.
- The **second letter** indicates the type of brush: 'E', 'A', 'U' for metal brushes; 'F', 'D' for metal plate fork brushes; 'C', 'K', 'H', 'S', 'T' for carbon brushes.
- The **third number** refers to the rotor diameter.
- The **fourth number** specifies the length of the magnet or housing.
- The **fifth number** denotes the number of rotor slots: '0' for 3 slots, '5' for 5 slots, and '3' for 12 slots.
This standardized labeling system ensures ease of identification and selection for engineers and technicians working with micro motor applications.
