Aninductionmotoror asynchronousmotoris an AC electricmotorin which the electric current in the rotor that produces torque is obtained by electromagneticinductionfrom the magnetic field of the stator winding.[1] Aninductionmotortherefore needs no electrical connections to the...
The electrical power lost in the primary rotor and secondary stator winding resistance are also called copper losses. The copper loss varies with the load in proportion to the current squared - and can be expressed asSee full list on engineeringtoolbox.comThese losses are the resultofmagnetic energy dissipated when when the motors magnetic field is applied to the stator core.See full list on engineeringtoolbox.comStray losses are the losses that remains after primary copper and secondary losses, iron losses and mechanical losses. The largest contribution to the stray losses is harmonic energies generated when themotoroperates under load. These energies are dissipated as currents in the copper winding, harmonic flux components in the iron parts, leakage in...See full list on engineeringtoolbox.comElectrical motors constructed according NEMADesign B must meet the efficiencies below: 1)NEMA Design B, Single Speed 1200, 1800, 3600 RPM.
