CA 2717416

Circuitry (e.g., 7, 9) for controlling motors (e.g., Figs. 2A and 2B), such as a brushless motor (BLM). is disclosed. The circuitry (e.g., 7, 9) may comprise one or more inputs for receiving rotor position signals (e.g., 91, 92) from one or more Hall effect sensors (e.g., 3) that detect the position of, for example, a BLM rotor (e.g., Figs 2A and 2B). The circuitry (e.g., 7, 9) may also comprise an input for receiving a pulse width modulated speed control signal (e.g., 114, 320). The circuitry (e.g., 7, 9) generates one or more drive signals (e.g., 322, 324, 326, 328, 41 -42, 43-44, 41 -42 (PWM), 43-44 (PWM)), each of which may com- prise a Jogicai combination (e.g., a logical AND combination) of the speed control signal (e.g., 114, 320) and a rotor position signal (e.g., 91, 92), for controlling power switches (e.g., F1-F8) that are coupled to electromagnets of the BLM (e.g., Figs. 2A and 2B).

La présente invention concerne des circuits (par exemple 7, 9) conçus pour commander des moteurs (voir par exemple les figures 2A et 2B), tels quun moteur sans balai (BLM). Les circuits (par exemple 7, 9) peuvent comprendre une ou plusieurs bornes dentrée pour recevoir les signaux de position du rotor (par exemple 91, 92) provenant dun ou de plusieurs capteurs à effet Hall (par exemple 3) détectant la position, par exemple, dun rotor BLM (voir par exemple les figures 2A et 2B). Les circuits (par exemple 7, 9) peuvent également comprendre une borne dentrée pour recevoir un signal de commande dimpulsion à vitesse modulée (par exemple 1 14, 320). Les circuits (par exemple 7, 9) génèrent un ou plusieurs signaux dentraînement (par exemple, 322, 324, 326, 328, 41-42, 43-44, 41-42 (PWM), 43-44 (PWM)), dont chacun peut comprendre une combinaison logique (par exemple une combinaison logique ET) du signal de commande de vitesse (par exemple 1 14, 320) et un signal de position du rotor (par exemple 91, 92), pour commander les interrupteurs de puissance (par exemple F1-F8) couplés aux électroaimants du BLM (voir par exemple les figures 2A et 2B).
