- the electromechanical conversion efficiency is significantly increased. For example, even when the locker door has a load of 50 N, it can be solved with 2 W of electric power. Can be locked. In addition, by making the size smaller, it is possible to solve the problem of squeezing the storage space of the locker.
- the coil temperature rise can be suppressed to 70K or less even when the solenoid is continuously energized.
- the power consumption for unlocking is 2W, which is less than 10% compared to the existing technology. This means that when batteries of the same capacity are used, the number of unlockable times (or battery life) exceeds 10 times, and the power consumption required for unlocking is extremely small. Therefore, in the electric lock that operates with this minute amount of electric power, when the battery is used, the battery replacement period becomes long, so that the number of times the worker replaces the electric lock can be reduced and the burden can be reduced.
