Although unbalanced magnetic pull can affect other rotating electric machines such as DC motors and generators and single-phase motors and generators, our focus in this article will be on three-phase squirrel cage induction motors. The two main topics are unbalanced magnetic pull (UMP) and rotor pullover.

Aunque la tracción magnética desbalanceada puede afectar a otras máquinas eléctricas rotativas, como los motores y generadores de CC y monofásicos, nuestro enfoque en este artículo se centrará en los motores jaula de ardilla trifásicos. Los dos temas principales son: La tracción magnética desequilibrada (UMP) y el descentrado del rotor (pullover).

Adhering to a few specific management styles can improve leadership effectiveness. A good leader recognizes the importance of employing the right management style at the right time to increase productivity, boost morale, encourage retention and manage crisis.

Determining the source of noise in a motor is often much more challenging than correcting it. However, a methodical approach to investigating the noise can narrow down the possible causes.

One of the most briskly debated issues in our industry is the comparison – and procedures for – vacuum pressure impregnation (VPI) versus dip & bake. For this article, the discussion has been expanded to include trickle epoxy and B-stage coils.

Uno de los temas más debatidos en nuestra industria es la comparación y los procedimientos de impregnación a presión al vacío (VPI) versus inmersión y horneado. Para este artículo, la discusión se ha ampliado para incluir bobinas de etapa B y epoxi de goteo.
