Regardless of the manufacturer of a ventilation or air conditioning system, ventilation systems pose a potential risk to human health if maintenance is unsuitable. To reduce the existing risks, operators are obliged to carry out a risk analysis and to set up the maintenance cycles in accordance with the manufacturer’s minimum specifications and to implement accordingly. It must be taken-into-account which type of ventilation system is operated. In a pure air circulation system, the air must be freed of dust [...]

MOTOR POLES & RPM & HZ

The speed a synchronous motor will run can be determined by the number of poles of the motor and the frequency of the electrical service using the formula: RPM = Hz* (2 / poles) * 60 where RPM = shaft rotation speed or revolutions per minute Hz = frequency or cycles/sec Poles = number of poles of your motor. So, for example, if you have a 4 pole motor on 60 Hz then RPM=60*(2/4)*60=1800 rpm. 60Hz is the most common frequency in the US 50Hz is the [...]
