  • Predicting Variable-speed Fan Performance from Motor and Impeller Characteristics - Part I. Using Complete Motor Data
    Background Motor Simulation Performance prediction of fans with triac-based speed controllers is a complex matter because transient and chopped waveforms of voltage and current generated by the triac results in degraded motor performance. Several researchers have developed prediction models that required estimation of equivalent circuit parameters from laboratory tests. The steady state performance of triac- controlled PSC motors was obtained by Novotny and Fath (1968) using space-techniques and numerical analysis.
  • Multi-speed control of single-phase induction motors for blower applications
    Triac bridge circuit used to implement electronic pole-changing speed control . To predict the transient and steady-state performance of a PSC motor controlled by this circuit, a dynamic simulation model has been implemented on a computer.
  • CR4 - Thread: Speed Changing Of Single Phase Motor
    Because they are inherently current limiting, Shaded Pole motors can simply be controlled via voltage control, ie a rheostat. So lowering the voltage lowers the torque, which indirectly results in a lower speed . In a PSC motor, the capacitors are always in the circuit , but are in series with the windings so the dI/dt is dampened by the inductance, and because there is no speed switch, the capacitors are DESIGNED to be in the circuit …
