| description | The article substantiates the effectiveness of the analysis of rotor
currents of asynchronous electric drives with frequency control. It
is proposed to use a spectral analysis of these currents, their main
harmonics as the most accurate «display» of slip in an induction
motor - as a method for assessing the quality of the motor torque
generation. Modeling and experiments confirm the proposed
theoretical propositions. These experiments demonstrating the
operation of the drive at low loads corresponding to a slip of 3%,
with a load close to the nominal corresponding slip of 8-10%,
convincingly demonstrated that the torque generation algorithm
implemented in standard frequency inverters (for example, ATV,
Schneider Electric) is not the most effective, at the same time,
a constructive solution is proposed that improves the dynamics
of the drive by almost half, making it close to the dynamics of
permanent magnet motors. This solution will allow the use of
asynchronous electric drives in precision technology. |
