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
