Option 3 : Energy
A motor meter is an Induction type energy meter that consists of the following components
Operating torque system (driving system), moving system, braking system, registering system.
- Driving system: the driving system of the meter consists of two electromagnets. The core of these electromagnets is made up of silicon steel lamination.
- Moving system: this consist of an aluminum disc mounted on a light alloy shaft. This disc is positioned in the air gap between series and shunt magnets
- Braking system: A permanent magnet positioned near the edge of the aluminum disc forms the braking system. The aluminum disc moves in the field of this magnet and thus provides a braking torque.
- Registering system: The function of a registering or counting mechanism is to record continuously a number that is proportional to the revolutions made by the moving system.
