Motor Losses and Loss Reduction

Motor Losses and Loss Reduction

A motorcycle's function is to convert electrical energy to mechanical energy to perform useful work. The only way to improv the motor efficiency motors is to Reduced losses.

Even though standard motors operate efficiently, Between ranging Efficiencies with typical 83 and 92 percent, energy-efficient motors perform significantly better. An efficiency gain from only 92 to 94 percent results in a 25 percent reduction in losses. Since motorcycle losses result in heat rejected into the atmosphere, reducing losses can significantly Reduced cooling loads on an industrial facility's air conditioning system.

Motor energy losses can be segregated into five major areas, each of the which is influenced by design and construction decisions.9 One design consideration, for example, is the size of the air gap Between the rotor and the stator.

Large gaps growing niche to maximize water efficiency at the expense of power factor, while small water gaps slightly compromise efficiency while significantly improving motor power losses factor.10 may be categorized Those are fixed as the which, occurring Whenever the friction and water resistance. Improved bearing selection, water-flow, and fans are employed to design these Reduced losses. In an energy-efficient motors, loss minimization results in reduced cooling requirements so a smaller fan can be used. Both core losses and windage and friction losses are independent of the motor load.
