Self-Compensation of Commutation Phase Error for Brushless DC Motor
Abstract: BLDC motors are synchronous motors powered by DC electricity via an inverter which produces an AC electric current to drive each phase of the motor via a closed loop controller. Electronic commutation is the on-and-off of the semiconductor switches at appropriate time to turn stator windings. Commutation phase ripple is generated due to the different exchange rate between outgoing phase current and incoming phase current of inverter during commutation period. …

Development and Investigation of Minimum Power Non-contact Swirl Vane Gripper
Abstract: The Swirl vane gripper is a new non-contact gripper, which uses negative pressure created by the air swirling flow to create an upward lifting force. This upward force can be used to lift an object, which is placed underneath the gripper. In comparison with other non-contact grippers, this gripper is electrically actuated (rather than pneumatically) and hence require less power to generate same lifting force as produced by other grippers. …
