Sinusoidal

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

    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
