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: [...]
Comparison between Axial fans and Centrifugal fans
There are many industrial fans manufacturers, but what do they do really. In reference markets, the term “industrial fan” does not have a clear definition and in this article, we want to explain what are industrial fans and answer to many other questions. There are only two basic types of industrial fans: Axial Fans and Centrifugal fans. The other many fans and blowers fall under various classifications like Industrial Blowers, Industrial Ventilation Fans, Exhaust Blowers, Industrial Exhaust Fans, HVAC fans [...]
The main parameters for a fan
The main parameters, characteristic to a fan, are four in number Capacity (V) Pressure (p) Efficiency (η) Speed of rotation (Rpm) Capacity The capacity is the quantity of fluid moved by the fan, in volume, within a unit of time, and it is usually expressed in m3/h, m3/min., m3/sec. Pressure The total pressure (pt) is the sum of the static pressure (pst), i.e. the energy required to withstand opposite frictions from the system, and the dynamic pressure (Pd) or kinetic energy imparted to the moving fluid (pt = [...]
