    Lock 1.2.1 . LISA Model The lock consists of a media on which the following are assembled: Description 1) Micro contact / Micro switch No. 1: It detects the open position of the lock. The deadbolt presses on the micro switch blade when the lid strike plate is completely released.

  • Page 12: Motor

    Motor It is a three phase induction motor powered in variable frequency. It has an integrated over temperature sensor. It measures the heating of the internal motor winding, and sends a signal from 130 degrees Celsius. It then sends the message “ERROR 04”. Speed sensor The speed sensor is a Hall Effect magnetic sensor, placed under the motor.

  • Page 13: Absorption Of Vibrations

    Absorption of vibrations Any system has its own resonance frequency, which will cause oscillations. The dissipative elements of these oscillations, which translate into vibrations, are anti-vibration mounts, numbering 4, coupled by an absorbent foam. This set will allow for absorbing parasitic movements whatever the rotor, its load, and its speed, providing that the load is balanced.
