What is a Monoblock pumps?
A Monobloc pump is a pump in which all rotating parts are mounted on a common shaft. The main components of a Monobloc pumps are Pump assembly and Motor assembly. Since there are 7% losses in belt driven sets and 3% losses in coupling driven sets hence to avoid these transmission losses Monobloc pump sets evolved. In monobloc pump sets as motor and pump are mounted on a single shaft there is no energy loss during energy transmission from motor to shaft.­­­­­­­­ By - Tanveer Ahmed Bankapur
Do you know what equipment is required to control the speed of motor shaft rotation angle of motor shaft and reverse the direction of motor shaft?
Variable Frequency Drive
Is there anyway it increase the power out put of a motor?
The power output of a motor can be changed by the use of gears. Gears can be used to increase torque by reducing the speed of the output shaft by placing a large gear on the output shaft, coupled to a smaller gear. Conversely, by using a small gear on the output shaft, coupled to a larger gear, the speed can be increased with a reduction in torque.
Reciprocating motion in an appliance is obtained from a rotating motor shaft with the aid of?

What is Friction in induction motor?
Friction is present at the motor shaft and also in various parts of the load. The friction torque is equivalent value of various friction torques referred to the motor shaft.
What makes vertical pumps not working unless you rotate the shaft first?
Bad Motor Start Capacitor
When power a fan using a simple electric motor the fan's shaft and blades are attached to?
Fans shaft and blades are attached to rotor shaft of the motor
What is the function of brake motor?
The shaft locks when power not applied.

What is closed coupling pumps?
In centrifugal pumps there are two major types of pumps,One is Bare shat pumps and another one is close coupled pumps.Bare shaft pumps having casing,bearing housing with shaft which has to be coupled by means coupling arrangements like love joy,Tyre and spacer type coupling with electric motor.But in the close coupled pumps the motor will looks like a inbuilt arrangement to avoid extra shaft length and shaft deflection. Still if you have a doubt on this subject feel free to mail me in horsepower@sify.com Mahesh M Kumar Executive Engineer INDUSTRIAL MONO BLOCK PUMPS Coimbatore

Can a 9 volt motor rotate 9 volt dynamo?
Are you going to use the 9-volt motor as a dynamo, and the 9-volt dynamo as a motor? Yes, the motor can rotate the dynamo because DC motors and DC generators are actually the same thing--they just apply power to the terminals of a motor to make it turn, and turn the shaft of a generator to make power appear at the terminals. Having said that, if you're going to try to connect the shaft of a 9v motor to the shaft of a 9v dynamo, and use the dynamo to power the motor so as to create a perpetual motion machine...that won't work. The motor wastes a little bit of energy, as does the dynamo. It is possible to build a device that uses a motor to drive an alternator, which is the AC version of a dynamo. You power the motor from the AC grid, and power something that's very sensitive to noise on the line from the alternator. This is called a Motor Generator set, and it's how they powered Cray-1 supercomputers.
How much power is developed by an electric motor that draws a current of 4 A when its operated at 240V?
P = I x V Power = volts x amps 240 x 4 = 560 watts. This is how much power will be consumed by the motor. The actual power produced at the shaft, will vary on type and efficiency of the motor.
If you have a pump with 260KW absorbed power at pump shaft and you want to run it on steam turbine then the steam consumption will be based on aborbed power by pump shaft or the steam turbine power?
Pump power is based on BHP = Hydraulic horse power + pump mechanical efficiency Absorbed power = BHP + electric motor eficiency in your case you dont need to account for power absorbed by pump shaft as it would include motor efficiency. your steam consumption will be based on following : normal operating = based on BHP of pump Maximum required = turbine rated power
What part of a boat rotates to power the boat forward or backward?
The oars or when a motor is used, the propellers on the shaft sticking in the water.
