APPARATUS AND METHOD FOR CONTROLLING BRUSHLESS ELECTRIC MOTORS |
摘要 |
A brushless direct current motor is energized by a power stage. Switches of the power stage are selectively switched by an electronic control device. In order to determine the correct commutation pattern, without using rotor position indicators, the control device is arranged to tap the power fed to the motor. The samples received by the motor, in an ordered sequence, define an analogue function whose parameters can be determined by vector addition. The computations applied to the sample enable the necessary commutating information and signals to be generated in a particularly rapid manner.
