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.
