| 1. | High-acceleration linear motors are difficult to design for a number of reasons.
|
| 2. | Linear motors have been used for sliding doors and various similar actuators.
|
| 3. | In contrast, end effects create much more significant losses with linear motors.
|
| 4. | The linear motor was naturally suited to use with maglev systems as well.
|
| 5. | Low-acceleration linear motors are suitable for maglev trains and other ground-based transportation applications.
|
| 6. | Compared to other drive mechanisms, the linear motor is typically maintenance-free.
|
| 7. | Linear motors are most commonly induction motors or stepper motors.
|
| 8. | Linear motors are being considered for the advanced weapons elevators.
|
| 9. | Motors that directly produce linear motion are called linear motors.
|
| 10. | However, the direct current homopolar linear motor railgun is another high acceleration linear motor design.
