What is another name for auxiliary winding?
2 Answers
Another name for an auxiliary winding is a "starting winding." This term is commonly used in the context of electric motors, particularly single-phase induction motors.
### Explanation
1. **Function**: The auxiliary winding helps to create a phase shift in the motor's magnetic field, which is essential for starting the motor. It works alongside the main winding to provide the necessary torque to initiate rotation.
2. **Design**: The auxiliary winding typically has a higher resistance and is designed to operate for a short duration, just until the motor reaches a certain speed. Once the motor is running, a centrifugal switch or an electronic relay often disconnects the auxiliary winding from the circuit.
3. **Types of Motors**: You'll frequently find auxiliary or starting windings in various types of single-phase motors, such as split-phase motors, capacitor-start motors, and shaded-pole motors.
Understanding the role of the auxiliary winding is crucial for anyone involved in electrical engineering or working with electric motors, as it is fundamental to the operation of many motor designs.

### Detailed Explanation:
1. **Function of Auxiliary Winding:**
- The auxiliary winding, or start winding, is used primarily to help start the motor. In single-phase induction motors, the auxiliary winding provides an initial phase shift to create a rotating magnetic field that helps the motor start. Once the motor reaches a certain speed, the start winding is typically disconnected from the circuit, often by a centrifugal switch or an electronic relay.
2. **Characteristics:**
- **Location:** The auxiliary winding is usually positioned on the stator of the motor and is distinct from the main or running winding.
- **Construction:** It is often made of a different gauge of wire or may have a different number of turns compared to the main winding to achieve the necessary phase shift.
3. **Alternative Names:**
- **Start Winding:** Emphasizes its role in starting the motor.
- **Starting Winding:** Similar to start winding, highlighting its purpose in the starting process.
- **Auxiliary Coil:** Another term sometimes used interchangeably with auxiliary winding, especially in more general contexts.
4. **Role in Motor Operation:**
- During the start-up phase, the auxiliary winding is energized along with the main winding. This combination creates a rotating magnetic field, which is essential for the motor to begin rotating.
- Once the motor reaches a predetermined speed, the auxiliary winding is disconnected by a switch or relay to prevent excessive current draw and potential overheating.
Understanding the role of the auxiliary winding is crucial for anyone working with or studying electric motors, as it directly affects the motor's starting performance and efficiency.
