Classic game for classic casino players, French Roulette realtime gaming coyote cash video slot game review PowerSines’ Sinusoidal Motor Efficiency Controller (SinuMEC)

SinuMEC, the Sinusoidal Motor Efficiency Controller, is a multifunctional controller for constant speed, variable load AC motors.  SinuMEC is built around power transformers controlled by microprocessor. This patented VVC technology enables dynamic control of the voltage level and power consumption according to the escalator motor load conditions, reducing losses and saving energy. 

Unlike Soft Starters and VSDs that alter sinusoidal waveform or change frequency, generating harmonics and electromagnetic interferences- SinuMEC supplies a pure sinusoidal waveform to the motor and guarantees smooth motor start and energy savings improving power quality and reliability.

SinuMEC Advantages for Escalators:

  • Reliable and Robust
    A heavy-duty motor efficiency controller that can work in harsh electric environments, such as public transportation sites, where accelerating or slowing down electric trains generates severe electrical disturbances
  • Re-generative Energy
    Uniquely designed to cope with re-generative energy, due to a down-loaded escalator, returning the energy back to the network without any additional filters or bypasses
  • Improved Power Quality
    SinuMEC has a very low THD and unlike VSDs it does not require any additional filters for suppressing harmonics
  • Motor Starter
    Smooth motor starting with typical startup current at only 2 x the nominal, thereby reducing electric stress on the motor and electric network; continued monitoring of motor performance improves electric efficiency while motor is running
