How does spooling improve efficiency of an os?
a lot
Is a electric motor a simple machine?
yes
Levers have a greater mechanical efficiency that other simple machines because?
They have to overcome less friction
Explain efficiency and how to calculate it for different simple machines?
Efficiency means to calculate that is the machine is efficient enough to save your bill or use less electricity. To calculate the formula is:Efficiency = Energy output (what is the machine producing) divided by Energy input (what is the machine taking or using).
In what two ways can the rotation of a shunt connected dc motor be reversed?
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
Difference between eff1 and eff 2 motors?
EFF1 is a high efficiency motor. EFF2 is a standard efficiency motor.
What is the efficiency and durability of the motor in the Shark vacuum cleaner?
The motor in the Shark vacuum cleaner is known for its high efficiency and durability.
What is the efficiency of a motor that has an output of 373 watts with an input of 450 watts?
The efficiency of the motor is calculated by dividing the output power by the input power and multiplying by 100%. In this case, the efficiency would be (373/450)*100 = 82.9%. This means that the motor is operating at an efficiency of approximately 83%.
A motor produces less mechanical energy than the energy it uses because the motor what?
Yes this is what we call efficiency of the motor. We give 100 but the motor in turn gives 40, so its efficiency is 40%
What factors influence the shape of an electric motor efficiency curve?
The shape of an electric motor efficiency curve is influenced by factors such as the motor design, operating conditions, and load characteristics. These factors can affect how efficiently the motor converts electrical energy into mechanical energy, resulting in variations in the efficiency curve.
What type of motor is recommended for a tricycle to ensure optimal performance and efficiency?
A brushless DC motor is recommended for a tricycle to ensure optimal performance and efficiency.

When is efficiency of 3phased Induction motor maximum what is the condtion for maximum efficiency in induction motor?
It is maximum at about 75% to 100% of the motor rated load. Efficiency is maximum at unity power factor , when R=X and when variable losses Is equal to constant losses at rated load.
Efficiency of motor?
I measure the efficiency of an internal combustian engine by doing (bhp)/((displacement)*(rpm))
How much energy does a motor convert to heat?
You can calculate the quantity of energy that a motor turns into heat with either one of these equations: Heat energy = ( 1 - efficiency of the motor) x (energy input to the motor) or Heat energy = ( 1 - efficiency of the motor) x (power input to the motor) x (running time)
What is motor efficiency?
Motor efficiency refers to the ratio of the mechanical power output of a motor to the electrical power input. It indicates how effectively a motor converts electrical energy into mechanical energy, with higher efficiency values indicating less energy loss during operation. Efficient motors help reduce energy consumption and operating costs.
Which motor is superior in efficiency and the most extensively used of all types of electric motors?
Motor efficiency depends on the motor size and how much it is loaded. You get the best efficiency above 75% of the rated load for that motor. Note the table below: Horsepower Standard Premium Efficiency Efficiency% Efficiency% 1 --- 78.0 --- 82.5 2 --- 78.5 --- 84.0 5 --- 84.0 --- 89.6 10 --- 84.0 --- 91.1 15 --- 87.5 --- 91.7 25 --- 90.2 --- 93.0 50 --- 91.7 --- 94.1 100 --- 91.7 --- 95.0 250 --- 94.1 --- 95.8
