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 [...]

The advantages of copper wire motor – Decent Machinery

Copper has one of the highest electrical conductivity rates among metals, which allows it to be soldered with ease. It also makes it possible for smaller conductors to be used to transmit power loads. Smaller conductors are easier to transport and install, and they cost less, which helps manage wiring costs. Copper doesn’t undergo the same extreme expansion and contraction cycles as aluminum so it is a more stable material to use. Due to its high ductile properties, copper can be [...]

How to Confirm the Centrifugal Fan Outlet Angle?

How to Confirm the Centrifugal Fan Outlet Angle? Fan rotation is determined by looking at the fan from the drive end. For centrifugal fans, discharge is the direction the fan outlet points. Specification of the rotation and discharge when ordering a housed centrifugal fan is required so that the fan will fit in your system properly. From the motor side to look the centrifugal blower,  1. If the centrifugal fan impeller clockwise rotation, it is right. The air outlet towards to the left horizontally: [...]
