A centrifugal motor is a motor that David Unaipon invented for his people but couldn't be created because he doesn't have enough money
What is used economizer in centrifugal chiller
Centrifugal pumps generally obey what are known as the pump laws. These laws state that the flow rate or capacity is directly proportional to the pump speed; the discharge head is directly proportional to the square of the pump speed; and the power required by the pump motor is directly proportional to the cube of the pump speed.
professor Auguste Rateau invented the centrifugal compressor,by 1899
Axial fans are like a propeller - like most domestic fans. Centrifugal fans are like water or paddle wheeels that sit inside a case. Instead of water turning them, the wheel is driven by the motor and that moves the gas. In-line merely means that the fan sits in the gas flow.
for a simple reason because it has high discharge than any other available pump. the centrifugal pump uses the centrifugal force to push out the fluid centrifugal force = (mass *velocity2)/radius. hence centrifugal force is directly proportional to the square of the velocity, in this case being the velocity of the fluid. power provided to pump proportional to the force exerted by the impeller.hence higher the power results in higher centrifugal force implying square of the velocity of the fluid. higher the velocity of the fluid higher the discharge of the pump.

A centrifugal switch, once the motor reaches near run speed, centrifugal force causes a set of contacts to open and disconnect the start capacitors. Some larger motors use a contactor which is disconnected by the centrifugal switch.
The hermetic compressor cannot use a centrifugal switch like an open motor because it will disrupt the start winding. Hermetic compressors work through insulated motor terminals, and not in the open.
Centrifugal clutches are seen most commonly in smaller motor cycles (50 cc) of the automatic type.
The centrifugal switch is likely to wear out and require replacement. It could also create a spark which could cause fumes from the oil inside the motor
3 Phase induction motor because it produce high torque at starting
In a single phase electric motor, the centrifugal switch allows the start winding to be energized through the start capacitor when the motor is starting. This gives an out of phase magnetic field that, along with the in phase magnetic field from the run winding, helps the rotor to begin spinning. Once the rotor reaches a certain speed, the centrifugal switch changes state and cuts off the start winding. At that point, the motor continues running only through its run winding, and inertia keeps the rotor properly phase biased relative to the run winding's magnetic field.

The 3PH motor has no internal contacts for a centrifugal switch and are therefore more durable when switched on and off frequently,
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
the centrifugal pump works on the principal of the centrifugal force when the shaft of the motor rotates the impeller connected to the shaft along rotates and the water that is surrounding the impeller get dragged out to the delivery pipe and creates a vaccum and fore the water again circulates in the chamber of the impeller and the cycle repeats on..
