Tips: What is a motor alarm?
The motor alarm is a motor driven siren that can be used for audible alarm in case of emergency. It is composed of the main parts such as the rotor, stator, positioning base, positioner, stainless steel cover, motor, base, etc.
- Rotor: It is the most important part of the motor alarm. It can generate sound source during high-speed operation.
- Stator: The part that highly matches the rotor usually has about 10 sound windows. The number of sound window is equal to the number of rotor vanes.
- Positioning base: The bracket for fixing positioner.
- Positioner: The sound window can be closed automatically when the rotor is in non-working state or stopped, to prevent rats, birds, spiders and other debris in the air from entering the motor alarm.
- Stainless steel cover: On the one hand, it is a sound reinforcement effect after the sound is refracted. On the other hand, it protects the entire alarm and prevents rainwater from entering the alarm.
- Motor: The power device of the alarm drives the rotor to make a sound.
- Base: The bracket of the whole alarm.
Motor alarm with high volume 180dB has optional working voltage 220VAC or 110VAC, cast aluminum alloy shell and protection class IP44. It adopts a single phase motor and two-way alarm mode to realize emergency alarm. The motor speed is 1000 rpm. Motor alarm can be used for alarm system of reservoirs, power stations, etc.
