Sinusoidal

Sinusoidal commutation smoothly transitions the current between all three phases as the motor turns resulting in reduced torque ripple.

sinusoidal

Advantages

  • Results in reduced cogging / torque ripple in low speed applications
  • Output power is constant through the entire electrical cycle

ADVANCED Motion Controls' Capabilities

  • DigiFlex® Performance servo drives provide sinusoidal output via Field Oriented Control (FOC) as the default commutation method for brushless motors
  • FOC provides smooth torque at low speeds with no phase lag at high speeds
