Trapezoidal

Trapezoidal commutation steps through 6 different commutation states per electrical cycle to transition the current between phases. Current passes through 2 phases at any given moment while the 3rd phase has zero output.

    Advantages

    • Results in increased overall torque, but with more torque ripple at low speeds
    • Compatible with low resolution Hall sensors for motor feedback to reduce overall system cost

    ADVANCED Motion Controls' Capabilities

    • AxCent brushless drives use trapezoidal commutation
    • DigiFlex® Performance drives can optionally be set for trapezoidal commutation
